How to properly install locks on metal doors? Installing a lock on a metal door Is it possible to install a lock on a metal door

It can hardly be said that a home is well protected if locks are not installed on metal doors. Of course, metal has earned consumer recognition for its strength and durability, but a high-quality lock plays an equally important role in home security. The peace of mind of the residents directly depends on its type, reliability, and design.

The need to replace or install a new lock arises when the old one breaks, the keys are lost, or the metal entrance door is replaced. The entire installation process takes more than one hour, and in most cases preference is given to companies that install door locks. However, there is another option - to put a lock on the metal door yourself. This is more difficult than with their wooden counterparts, but it is not difficult to learn a new skill.

Types of castles

A consumer who decides to change the lock on a steel door will be faced with a variety of existing models. The most popular of them are:

lever (its secret part consists of several plates, when displaced, the key can be turned);
cylinder (consists of a cylinder and a mechanism inside).

Cylinder models are more common because they have greater privacy. In addition, if the key is lost, there is no need to change the entire box - it is enough to update only the inside.

Level lock type

Cylinder locks are divided into mortise and overhead. When wondering what kind of lock to put on a metal door, it is best for the consumer to focus on the burglary resistance class. There are four of them:

Class 1 - devices with a low degree of protection (used inside offices, apartments, cabinets, cabinets);
Class 2 - normal (average) degree (recommended for metal doors, country houses, premises without expensive property inside);
Class 3 and 4 - increased and the highest degree of protection (they find a place where expensive things are stored - large companies, safes, banks, luxury apartments, private cottages).

Before choosing a security device, the buyer asks a logical question - how much does it cost to embed a lock into a metal door in order to ensure the security of the room at a cost? Installation of class 1 or 2 devices, including a visit by a technician, measurements, selection of a lock (similar to the old one), removal of the old one and installation of a new one, the warranty period and the device itself will be at least 2,500 rubles. A considerable amount, and we are talking about not the most reliable locks, because when installing high-security products, installers require 4,000-5,000 rubles. For this reason, it makes sense to study how to install locks on an iron door yourself.

Before purchasing, it makes sense to ask advice from knowledgeable people, familiarize yourself with popular lock models and take into account several nuances. Remember these rules:

A good expensive lock is better than two bad and cheap ones;
three pieces is too much, one device is too few;
it is desirable to install two locks of different types (level and cylindrical);
the cheapness of the model is also a headache during operation;
pay attention to other methods of home protection (video surveillance, alarm).

Before inserting a lock into the door, ask your consultant about the operating features, installation rules and other little things that may be useful.

Required Tools

Collecting the necessary equipment for work will not be a problem for men, since a real home craftsman has most of the equipment. To install the protective device you will need:

drill;
metal drills of different diameters;
angle grinder (“grinder”);
cutting and grinding discs for machines;
pliers;
screwdrivers;
tape measure from 3 m long;
hammer;
square;
coarse stone for sharpening drills (with its help it is convenient to expand the mounting hole in the door under the lock).

When the required tools are prepared, you can begin installing the protective device.

Installation sequence

To fit a lock into a metal door yourself, you don’t have to do anything supernatural. The task is complicated by working with metal - a cold, high-strength material. Following the steps below will give you the expected result.

Marking.

A lock will be installed at a level of 800-1000 mm from the bottom edge of the canvas. This place is marked so that the length is slightly larger than the dimensions of the castle. Along the edges (or corners) of the intended hole, tiny holes are made with a hammer and a core, indicating the points for drilling holes for the lock.

Drilling.

The key point is the correct drill diameter. It should exceed the holes for fastening the lock by a couple of millimeters.

Cutting a hole for the protective device.

Straight lines connect the drilled holes. Then a cutting disc (preferably small) is placed on the grinder and a rectangular hole is cut out. The operation should not be difficult except in the case when the door frame is made of a profile pipe. Here you will have to cut a hole on both sides.

Drilling holes for the cylinders.

The distance from the well is transferred to the door. The hole for the lock is drilled along the previously drawn contour with a dozen small holes. The closer they are to each other, the easier it will be to install a lock on a metal door. Next, using a grinder or drill, the holes are connected into a single locking slot. In place of the removed piece of iron, a device and a cylinder are tried on. If required, the hole is additionally bored with a grinder and a drill.

Drilling a hole for the door handle.

If the previous steps are carried out with proper accuracy, you only need to make a hole of the required diameter.

Lock installation.

The protective device is fixed in the door leaf, screwed with screws or self-tapping screws. Next comes the insertion of the cylinder from the end of the door. There is no need to immediately tighten the fasteners tightly - it is worth checking the functionality of the lock, its free movement without obstacles.

Installing a door handle.

This stage is carried out simply. The maximum additional work is drilling additional holes for fastening the fittings.

Making a hole for a bolt with a latch.

If the marking is made accurately, a strike plate is put on the lock bolt and its position is noted with the doors closed. Then the door is opened, the strip is again applied to the frame, the holes are more accurately marked and drilled using a drill.

The door lock installation is complete. It is worth checking the smooth closing of the device again and making sure that all the work has been done correctly. Obviously, the process is not as complicated as it seems. You can do the same if you need to embed an additional lock into a metal door. Only the second device should be of a different type for greater reliability.

Does it make sense to approach the matter responsibly, study all the nuances of installation and install protection on the front door yourself? Of course, even more so you can save a significant amount of money. If you are wondering how to embed a lock into a metal door, you can refer to the instructions presented above and do not the most difficult work with your own hands.

More and more residents of our country are installing metal doors in their apartments. They can increase home safety and protect property. But the “original” locks of such doors are a weak point. Therefore, more and more often, owners try to replace the lock themselves immediately after installing the door. And some even buy doors without a locking mechanism and install it themselves. This instruction will tell you how to do this.

What tools will you need?

Before proceeding directly to inserting the lock, you need to make sure that all the necessary tools are available. One of the main tools used for this work is an angle grinder with a metal cutting wheel mounted on it. Since you cannot work with an angle grinder without eye protection, make sure you have safety glasses or a special shield.

Also, to mortise the lock you will need an electric drill with a set of drills and a screwdriver. The presence of the latter is not necessary, but for comfortable work this power tool is preferable to a regular screwdriver.

Additional tools you may need are files and a tap for cutting threads.

Which door lock to choose

Any installation of a door lock begins with the selection of such a device. There are several rules, the main one of which is to install two locks of different designs on the front door. The cylindrical and lever locks complement each other well. In addition, you need to take into account that locks have different quality. And one door lock, even of average quality, will give odds to two bad locks.

Attention! A quality lock is a great way to protect your home from uninvited guests. But you shouldn’t neglect other ways to protect your home: alarms, video surveillance, etc.

When choosing a door lock, you should not rely only on its cost. If you don’t know what to choose, chat on specialized forums on the Internet. You can also ask the sellers of such products for advice. But can you be sure that they will tell you the whole truth?

Installing the lock

Before inserting a lock, it is advisable to correctly assess your strength. The installation of high-reliability locking mechanisms is best left to professionals. Firstly, the devices are quite expensive. And, secondly, errors when installing them yourself minimize their high quality.

The lock is installed in a metal door using the mortise method. This method helps to hide its mechanisms from external influences.

Step 1. Marking

Before inserting the locking mechanism, you need to mark the place where it will be installed. First you need to measure the height. It is most comfortable to use the lock at a distance of 90-110 cm from the floor. The center of the door end is marked. You need to attach a lock to it and use it to mark the places where the fasteners will be installed.

Taking into account the thickness of the mechanism, it is necessary to make markings on the side of the door.

Step #2. Preparing the insertion site

To prepare the socket for the mechanism body, use a drill and a drill. For this operation, it is very important to choose the correct drill diameter. It should be equal to the thickness of the lock. Its body should fit tightly into the hole made using a drill.

Step #3. Inserting the lock into the prepared place

We insert the lock inside the canvas. Mark the holes for the fastenings. Using a drill, we make holes and cut threads into them with a tap.

Step #4. Installation of keyhole and handles

We determine the location of the exit for the handles and the keyhole on both sides of the door. We apply a lock and make marks. We drill holes, install and secure all parts of the lock.

Step #5. Making space for the front bar

Using the markings you need to cut out a recess. The front strip is installed flush into this recess.

Step #6. Installing the striker plate

Installing a striker plate is quite simple. The main thing is to accurately position it relative to the locking mechanism. To do this, you need to close the door and mark the installation location of such a strip.

Attention! At each stage of inserting and assembling the lock, it is necessary to check its operation. Even the slightest misalignment in the markings or in the manufacture of holes can disrupt the operation of the locking structure.

Installing a rim lock

The overhead mechanism is easier to install than the mortise mechanism. But its installation must also be approached responsibly. Here you also need to first determine the location of the lock and mark it. It is customary to place rim locks higher than mortise locks.

After marking, fastening pins are installed on the metal door. Using the previously made marks, marks are drilled for the spring to come out. An internal overlay mechanism is installed on the pins.

If the operation of the lock is not in doubt, then you can secure the lock to the body.

Now you need to install the overhead block. It is screwed on from the outside. Holes are needed to attach it. It is very important to correctly mark the place for them. If the external and external parts of the lock do not match, its operation will be at risk. The crossbars may simply not fit into the recesses made for them.

Maintenance of the entrance lock

The main procedure for maintaining the front door lock is its periodic lubrication. After installing the locking structure, this is not necessary. Any new lock comes with factory lubricant. But over time it will be lost and the operation of the mechanism may be disrupted.

First you need to lubricate the bolt. To do this, they need to be pulled out as much as possible and a liquid lubricant applied to them. Then you need to push the bolt in, wait 30-45 seconds and repeat the procedure. In total, 3-4 such procedures need to be carried out.

It's not very difficult to fit a lock into a door. But, as often happens, without experience, few people manage to cope with such work on the first try. And the risk here is not only that the locking mechanism can be damaged. You can cause irreparable damage to the door itself. And this is completely different money. Therefore, it is best to entrust this procedure to professionals.

Installing a lock on a metal front door is not the easiest thing and requires a competent approach. Therefore, for those who are not confident in their abilities or have never encountered such work, it is better to call a professional. For those who want to do everything themselves, we recommend that you read our article.

Choosing a castle

Be patient before starting installation and choose the lock itself, which will serve faithfully for years. Finding a good castle is not so difficult now. It is important to know what exactly you want to purchase. In turn, we will help you make your choice and tell you about the main types of locks installed on entrance doors.

Now, taking into account technological progress, all locks that can be embedded in a metal door are divided into three groups - cylinder, lever and electronic.

All locks differ in class - locks of 3 and 4 reliability classes are considered the best, but locks of a lower class should be purchased for less important doors. It is better not to purchase locks whose packaging does not indicate the security class.

The most common are cylinder locks, the design of which involves the presence of specially shaped pins and a key with matching holes for them. Locks of this type, intended for entrance doors, have a disk code mechanism. These discs and the key have comparable cutouts and grooves.

No matter how complex such a lock may be in terms of secrecy, it will not cause problems for burglars, since the lock cylinder can easily be knocked out with a strong blow. However, high-end locks usually have an armored tab that protects the mechanism from this type of hacking.

Lever locks are so named because of the levers - steel plates, which, when the lock is opened with a key, are arranged in the order specified by it. The more such plates in the mechanism and the better the quality of the material from which they are made, the higher the class of the lock. These locks are also equipped with an armored insert, so they cannot be opened with a kick. However, you can select a master key for this type of lock.

Locksmiths advise purchasing and installing two different types of locks on the front door for greater reliability.

Electronic locks, due to their ingenuity and relative newness on the market, are more expensive than the two previous types. Some locks can be opened using a magnetic card, some can be opened using a remote control, and some can be opened by typing a code on a keypad.

Particularly wealthy residents can afford the luxury of locks that recognize the owner by a pattern on the finger or retina.

Installing a lock on a metal door

If you need to install or reinstall a lock on a metal entrance door, you will need a screwdriver, electric drill, grinder, drills, metal screws, taps and files. In addition, you will need a carrying device that matches the power of the power tool, as well as safety glasses and dielectric gloves.

When choosing a lock, pay attention to the thickness of the metal sheet on your door. A lock that is too powerful can damage the door if the material thickness is less than 3-4mm.

It is best to embed a lock into a metal door. This way you will hide and protect the lock mechanism from harmful external influences. If the lock plate is installed on the end of the door, then you can install such a lock yourself. If the lock has increased reliability and is hidden in the door so that you can only see the crossbars at the end, it is better to trust the professionals. Believe me, such a lock is worth the additional expenses for the work of a master.

In this case, we will not consider overhead locks - the inside of the door is too unreliable to secure such locks, and the appearance of the door and hallway will suffer.

Instructions for installing a door lock (video)

First, mark the place where the castle will be located. The best height for it from the floor level is 90-110cm. The markings should be carried out according to the dimensions of the lock.

Using two small drilled holes, mark the top and bottom boundaries of the lock mortise area.

Next, a grinder with a cutting disc comes into play - it makes two cuts from top to bottom along the vertical marking lines. If the resulting hole is slightly smaller than required, cut off the excess and remove the burrs with a file.

Now you need to insert the lock and mark the location of the mounting screws. Holes are drilled for them and the thread is cut with a tap.

The diameter for the screws is made slightly smaller than necessary - usually this difference is 0.2 mm.

Now you need to attach the lock to the door on both sides and mark a place for the keyhole. This place is drilled and cut with a grinder.

Now the lock itself can be inserted into the door, secured with screws and checked for readiness for operation.

We attach the pads to the door, insert the key into the lock and mark the places where we will make holes for their fastening using self-tapping screws.

The door tabs are secured on both sides, and the lock itself is again checked for smooth operation. The key should turn easily and not get jammed by the pads.

Holes for crossbars must be marked with special attention. If the ends of the crossbars are lubricated with something coloring (paint, chalk), the door can be closed and the key turned all the way. The necessary contours and marks will remain on the opposite part of the door.

The holes for the crossbars are drilled with a drill and cut out with a grinder. The same applies to installing overlays.

Are there other lock options?

When purchasing doors with an already installed electronic lock, you will be spared the hassle of fiddling with installing the lock. All that remains is to come up with an electronic digital key.

As soon as you come up with a code, save it in your head. Now no one except you can open the lock, not even the master who installed the door and connected the lock.

True, if you are well versed in electronics and electromechanics, it will be even easier for you to install such a door yourself than a regular mortise lock.

The need to insert a lock into a metal door may arise for various reasons, for example, you purchased a new entrance door or decided to update an old locking mechanism. If you do it yourself, you can save money, but if the work is done poorly, there is a risk that the mechanism will quickly break down or your home will be broken into. Let's figure out what you should pay attention to in order to avoid mistakes.

The technology for installing a lock on a metal door can vary significantly depending on the type of locking mechanism

Required Tools

Doing such an important job with your own hands is actually not that easy. In addition to knowledge of the features and installation technology of locking fittings, skills in working with various tools will also be required. In addition, it is important to follow safety precautions when working with them.

To install a lock into a metal door, you may need the following tools:

drill;
set of drills;
core for metal;
tape measure and pencil;
self-tapping screws and self-tapping screws;
screwdriver;
screwdriver;
file;
thread tap;
Bulgarian.

The necessary set of tools for installing a lock on a metal door

When using power tools, it is very important to ensure that there is no risk of electric shock. Use special protection and use only high-quality tools and extension cords.

Be sure to take care to protect your face from sparks and iron filings.

Lock selection

In order for the door to perform its functions, it is important to install a suitable lock on the entrance structure. The choice depends on many factors. First of all, it should be borne in mind that not every lock can be installed on an iron door. It must be selected for the specific thickness of the product.

It is also necessary to distinguish between models according to the installation principle:

Invoices. Installing a rim lock is the simplest option, since the main part of the mechanism is located outside.
Mortise. The lock must be inserted into the body of the canvas, having previously cut out part of the material.
Built-in. These models are installed at the door production stage, and therefore they are practically not installed with your own hands, since to do this you need to completely disassemble the door leaf.

Types of door locks depending on the installation method

Systems are also distinguished by degree of reliability, level of secrecy and type of mechanism:

cylinder;
level;
crossbars;
disk;
electronic;
magnetic.

The first two types are most often used. The principle of their installation as a whole is not much different, but in some points there are significant differences. Let us consider in more detail the stages of work on installing mortise and overhead models in an iron door. The most popular today are mortise models, so you should start with them.

Installation technology for a mortise model

In order to install a mortise lock on the front door, it is necessary to make not only holes in the door leaf for the hole and handle, but also to deepen the mechanism inside. The work will not be easy, and it is also important to accurately determine the position of all fasteners and external outlets.

Installing a mortise lock model is a rather labor-intensive process for a beginner

How to properly embed a lock into a metal door with your own hands:

Mark the position of the lock using a tape measure and pencil. Usually the height ranges from 100-150 cm.
At the end of the canvas, mark the boundary of the recess. Using a drill, drill holes along the edges, and then cut out the inside with a grinder. File the edges to remove any rough edges or nicks. To ensure that the drill does not move, you must first work out the marks with a core.
Insert the lock inside the canvas and mark the position of the fasteners. According to these marks, drill holes for the screws and cut the threads using a tap.
Next, you need to determine the location of the keyhole exits and the handle lever on both sides of the door. Attach the lock to the canvas and make marks. Then drill large enough holes and secure all the pieces in place.
Check the operation of the mechanism. If everything is in order, install the handle and screw the cover panel. Lubricate the core and rotate the bolts several times.
On the opposite side of the box you need to cut it out with a grinder or drill holes for the lock bolts. A counter plate is attached to the top.

Since intermediate manipulations can lead to movement of the lock, check the functioning of the mechanism after each operation. Identified problems must be corrected immediately.

Installation of a rim lock

The installation of a rim lock is performed slightly differently. Here the main part of the mechanism is located above the canvas, and not in its inner section. It is important to ensure reliable fixation of the lock on the surface, bring its reverse part out and create conditions for locking the bolts on the mating part.

How to install a rim lock on a metal front door with your own hands:

To begin, attach the lock to the canvas and make markings. It is necessary to note the position of the holes for fastenings, pins, well exit, etc. Please take into account that overhead models are usually placed higher than mortise ones, that is, at a comfortable level for using the latch.
Install the mounting pins on the metal door.
Using the previously made marks, drill a hole for the well exit to the outside of the door.
Attach the overhead mechanism to the pins on the room side.
Check the operation of the lock and, if everything is in order, screw the housing onto the blade. An overlay is mounted on the reverse side.
An overhead block is used to fix the crossbars. It is screwed onto the opposite side of the box. To do this, drill holes in the frame and cut the threads. Then tighten the panel with screws. It is important to maintain the exact location of the counter part relative to the main lock. Otherwise, the crossbars will not fit into the recesses intended for them.
In some overhead models, you can cut standard recesses in the box with a counter plate. To do this, one condition must be met: the box must protrude to the level of the lock. This mainly applies to wooden structures, but metal models can also be designed in this way.

If you are sure that the task does not present any difficulties for you, get to work. If you lack knowledge and skills, it is better not to undertake such a complex installation and entrust this work to the masters.

Situations often arise when you need to install a lock on a metal front door. This is necessary if it is made by yourself; you need to embed a second locking mechanism for greater protection. The easiest way to do this is to call a special service department, but in most cases, installing a lock on a metal door is not so difficult, so the installation can be done on your own. This will save you some money.

Selecting and purchasing a locking mechanism, one or two, is the first step in installing it. Locks differ in their class of resistance to burglary; the higher the category, the greater the protection the mechanism guarantees and the longer the attackers will have to tinker with it.

For an apartment or country house, it is worth acquiring locks of resistance class 3 or 4; products of lower categories (1 or 2) are suitable only for utility rooms.

If a product does not have a burglary resistance class indicated, you should not buy it.

It is possible to install locks on the iron entrance doortwo types:

Cylinder. They are widespread. Their design includes pins of a specific shape, as well as a key with recesses for them. This type of lock has a disk code mechanism. Despite its complexity, the larva of such a device can be damaged quite easily - knocked out. Therefore, it is worth purchasing premium products that have an armor plate. It protects the mask from being knocked out.
Level ones. They got their name because of the plates (levers). When the lock opens, they line up in a clear order. The greater the number of levers, the more reliable the lock (its protection class is higher). Armored plates are also installed in such locks.

Since each type has its own specifics and disadvantages, the best option is to install two locks with different mechanisms in a metal door. This will ensure the maximum degree of property protection. But the whole process takes quite a long time. In this case, a specialist will help solve the problem. The technician will install locks on a metal door quickly and efficiently.

In addition to mechanical locking mechanisms, electronic locks are installed in iron doors. They open using a remote control, a magnetic card, and the most modern models respond to a fingerprint.

According to the installation method, locks on an iron door are divided into the following categories:

Invoices. Almost the entire lock is located outside the sash. Installing it is quite simple on your own.
Mortise. The most common option. To install a lock on an iron door, a hole is cut out in the door leaf. Externally, this is the best option, since the lock is not visible.
Built-in. The insertion of locks into an iron door is carried out into the leaf during the assembly stage of the product at the factory. Replacing or installing such a lock on your own is quite problematic; you will have to completely disassemble the sash.
Mounted. This type is not used for residential premises; it is suitable only for change houses or outbuildings. To mount it on a metal sheet, lugs are welded.

You should not buy cheap products, otherwise you will have to spend money later on repairing or replacing them. It is better to purchase one high-quality and expensive lock with a high level of protection than two cheap and easy to open ones. In addition, cheap mechanisms begin to jam after a short period of operation. That is, you will again need to put a lock on the entrance metal door.

But you shouldn’t go to the other extreme and install as many locking mechanisms into the canvas as possible. Cutting into each element gradually weakens the sash. Therefore, experts do not recommend installing more than 2 locks. For maximum protection, it is better to install two doors to the apartment (entrance and vestibule).

Preparing tools

To insert a new lock on a metal door or replace an old one if it breaks, you don’t need complex tools. You will need a grinder and a drill, a screwdriver. For the drill, you should purchase drills of 12 -18 mm in diameter. It is also good to have a coarse-grained sharpening stone so that, if necessary, you can easily expand the technological holes and polish them, removing roughness.

You also need a file, screwdrivers, and a tap for threading. For marking, you should prepare a tape measure and a pencil. From fastening elements it is necessary to make a supply of screws and self-tapping screws. That's the whole set, it can be found in every owner's home.

The difficulty of installing a door lock on a metal door is that you will have to work with metal of considerable thickness and strength. For overhead and mortise locks, the method of installation is slightly different.

When carrying out any repair work, you must not forget about your safety. Therefore, it is better to work with protective gloves, and wear goggles when cutting metal.

Installation diagram of a mortise lock

To insert a lock into an iron door, you will need to drill several holes: they are needed for the handles, the mechanism itself, and also for the well.

Inserting a lock into an iron entrance dooris performed in the following sequence:

Mark the location of the lock. The most convenient height for its installation is from 1 to 1.5 m. You can also place the lock at a distance of 80 or 90 cm from the floor.
In the end area of the sash, mark the edges of the groove. Make small indentations at each end of the marking made with a drill, then between them you will need to make a notch using a grinder. To prevent the drill from “driving” on the metal, you can first make light dents with a core and a hammer. For drilling, it is important to choose a drill of appropriate diameter; it should be 2 mm larger than the thickness of the lock.
Cut a hole for the lock. Connect the drilled edges with lines. Now you have to work with a grinder; it is better to use a small tool. If the door is made of profile, then you will need to cut a hole on both sides. A small grinder is perfect for this type of work. After making the hole, be sure to file the edges so that they are even.
Make a hole for the lock cylinder. At the next stage of inserting the lock into the entrance metal door, it is necessary to calculate the distance from the well to the edge of the device and transfer the markings to the door. Also at this stage you need to make markings in order to install the door handles later. It is best to draw the outline of the castle on the canvas, and make small holes with small pitches along its perimeter, which are then connected into a single whole. After the slot is made, remove the metal, insert the lock (try it on), if necessary, bore the hole to the required dimensions. This can be done with a drill equipped with a small abrasive wheel. The cylinder should fit well into the lock.
Make holes for fixing the handles. It's simple: just drill holes of the required diameter.
Place the mechanism in the door leaf body and mark the points for its attachment. For the fixing screws, make holes, then use taps to form threads in them.
Install the lock. Insert the iron door lock (into the prepared slot), fasten it with screws or self-tapping screws. Often fasteners are included with the device. Then install the cylinder and connect it to the lock. To do this, you will need a long screw that is inserted from the end.
After tightening the screws, check whether the lock works properly. If everything is in order, install the door handles and trim. Lubricate the core with machine oil or other lubricant, check how the crossbars work.
Now you need to make a counter hole in the box into which the latch and bolt will fit. First make the markings, you need to do this as accurately as possible. You can hang a counterplane on the bolts of the lock, cover (close) the sash as much as possible and in this position mark the edges of the striker. Drill appropriate recesses in the door frame for the crossbars. Record the answer.

To prevent any shifts from occurring, you need to regularly check the functionality of the mechanism as you install the lock.

After inserting the lock into a metal door, for normal operation of the mechanism, it is important to periodically clean it from dust and dirt and lubricate the mechanism. New products already contain lubricant, but those that have worked for several months require maintenance. To lubricate the crossbars, you need to extend them to the maximum, distribute the lubricant over them, and push them back. After 40 seconds, repeat this procedure again. Do this 3 or 4 times. Also, for normal operation of the locks, do not allow the sash to sag. To do this, you need to adjust the hinges and correct their operation, select canopies that are suitable for the weight of the canvas.

Installation procedure for a rim lock

This type of lock is easier to install, since the main part is located on the sash, and not in the middle.

To install a lock on a metal entrance door, you will need to perform the following steps:

Attach the lock to the sash, make marks for its fastening, the hole and all other elements. Locking devices of this type are usually installed higher than mortise ones. This is done so that the latch can be used more conveniently.
Mount pins for fastening on a metal sheet.
According to the markings, make a hole for the well to exit to the outer side of the sash. Secure the rim lock using the pins from inside the room.
Check how accurately the mechanism works. If there are no problems, finally fix its body on the sash. Install a trim on the outside of the door.
Make a recess in the box, make a thread, and install an overhead block. It is necessary to fix the crossbars. It is important to do everything correctly, otherwise the crossbars will not fit into the corresponding recesses.

You can install a lock on an overhead-type metal door yourself without any special skills. This is much easier to do than to cut it in. The process itself takes a little time.

Replacing a cylinder lock

Installing locks on a metal entrance door equipped with a cylinder mechanism is very common, since in the event of a breakdown there is no need to insert a new lock. It is enough to replace only its damaged larva.

The core is made in the form of a cylinder; updating such a device is not at all difficult.

First you need to remove the spent larva.
After this, using a special key you need to open the mechanism. There is no need to remove any other elements of the lock.
From the end side, unscrew the screws that secure the lock plate.
Using the key, close the device. Unscrew the screw in the center of the tongue.
Turn the key 40 degrees and pull the cylinder upward.

Replacing a lever-type lock

There are a lot of manufacturers of lever locks, but when choosing them, you should give preference to European brands, since they are much easier to repair. If such a device fails, then its spent core must be replaced.

To install a lock of this type in a metal door, it is necessary to dismantle the existing housing. To do this, open the door so that the crossbar elements are visible. Then remove the lock core. You need to remove the armor plate, deadbolt, handle and key. There is no need to remove decorative elements.

After this, unscrew the fixing screws and remove the old part. Then install a new core and secure it. In some cases, it is not necessary to replace the lock element, and for better operation it is enough to simply recode the mechanism using a special key and instructions that come with the product.

At the next stage, you will need to drill holes of a suitable size for them. Fix the plate on the metal sheet using special washers. To ensure sufficient strength, you need to install a pair of washers on each screw. The steel washer is screwed on first, then the rubber one. This ensures a tight fit of the core.
Select the location where the corner of the device will be located. Combine the main part with the anchor element. Use a hexagon for fixation.
To check the correct installation, slightly loosen the fixing bolt. This will release the counter plate.

After this, you can connect the power supply and check how well the lock works. The main condition is the correspondence of the plate and the base. If the parts are displaced in any way, the mechanism will not work.
