Inserting a lock into an interior door: mechanisms and types, installation procedure, tools and nuances. Instructions for installing locking mechanisms in an interior door, features of inserting a lock with a handle How to properly install a lock on an interior door

The reliability of metal doors will never replace the beauty and environmental friendliness of their wooden counterparts. However, such products have their own characteristics, and they also relate to the installation of locks. You can even do this kind of work with your own hands if you know how to do it.

Required tools and components

Inserting locks into wooden panels requires the use of:

• wood drill;
• a set of steel crowns;
• a set of chisels;
• roulette;
• construction pencil;
• screwdrivers - slotted and Phillips;
• drills;
• screwdrivers;
• hammer.

The selection of the lock plays a very important role. In this case, they focus on the size of the structure. An excessively thick lock will not allow the required mass of wood to be provided on the left and right sides. If there is less than 1 cm of wood left there, the door will not be strong enough. A kick is enough for the entire canvas to crack.

Additionally, it is necessary to control the depth of the lock entry. Some of the canvases are thicker on the outside than in the center. The glazed part can also present difficulties. If you have to prepare a place to insert a large lock, it is easy to deform the material. As for fasteners, they must be selected in accordance with the instructions from the manufacturers.

Often you can't get by with a drill or angle grinder. The optimal device for inserting locks into doors made of solid wood or other wooden materials is considered to be a manual router. Although "almost ready" lock mortise kits are relatively inexpensive, professionals advise choosing each tool individually. This allows you to finally be sure of its quality (both when purchasing and when renting). In addition, this solution helps to save money.

Sequence of work

If the product is selected properly, you need to correctly embed the lock into the wooden door. They start by applying the lock to one of the sides, in the right place. Using a construction marker, trace the part - using the drawn lines you can finally determine whether the choice of lock and location is correct. If there are no errors, the position is marked on the end face of the door. When the set contains a special paper template, use it.

Take a feather drill, the thickness of which is chosen very carefully. Then, using a screwdriver, passes are prepared to form a vertical line. The outer edges of the holes must be mutually adjacent. If the required drill is not available, smaller drills can be used. They arrange holes in 2 or 3 tiers.

Now you need to take a chisel, which allows you to remove excess wood. A slotted screwdriver is a substitute for a chisel, but such a tool is not convenient enough. Then they insert the product into the prepared place, trace the end strip with a marker and pull out the closing part. Strictly along the line, 0.2 - 0.3 cm of wood is removed. This will allow the lock to be deepened into the door, placing the bar flush.

This technique is used when installing locks to prevent the strip from hitting the surface of the box. If the gap is large enough, you can skip this stage. The next step is to mark on both sides the space for the key hole or for the lock cylinder. If the structure has handles, marks are also made for them. The lock is pulled out and drilled in the marked places.

Now you can insert the lock back and evaluate the correctness of the prepared holes. The larva (if any) is fixed with a screw from the end. Next, insert the square base from the handles, screw the handles themselves. The key is inserted and the lock is immediately checked. Opening and closing should be easy, without the key rubbing against the wood.

Then it’s time to mark the holes for the crossbar elements and the striker plate. The easiest way to do this is to do it yourself using paste. When the door is fully open, the lock is locked and the end of one or more bolts is lubricated. Next, you need to open the bolt, close the door, and lock the lock. Normally it will not lock, however, paste tracks will appear. They will indicate how and where to make the holes for the counter block. They are drilled immediately to eliminate mistakes.

A counter plate is applied to the holes and a mark is made along its contour with a pencil. Using a chisel, remove part of the wood. This will deepen the bar. All that remains is to secure it. Now the door is closed and the lock is checked again. When everything works fine, decorative overlays are installed. That's it, you can enjoy excellent results. There is nothing complicated about this.

To ensure an exact match between the actual and planned depth of the holes, electrical tape is glued to the drill. You can select the remaining wood with a chisel. Later the walls are leveled with a chisel. We must strive for groove sizes that will allow the inserted lock to coincide with the end face of the door. This means that when hollowing out a socket, periodic fittings of the product are required.

To make a shaped groove for a keyhole, you need to use a hacksaw. The edges are brought to an ideal shape using sandpaper. Since they are not comfortable enough to work by hand, you can attach the paper to a screwdriver. It is best to use a thin drill bit. The installation of the strike plate for mortise and overlay mechanisms is no different.

It is recommended to choose a drill bit that is thicker than the lock. Usually several notches are drilled so that the web filler can be removed. When drilling is completed, use a chisel and chisel to remove excess debris. But all these rules may turn out to be useless if one more principle is not followed: as soon as something is measured with a tape measure, you must immediately mark it with a pencil or marker. Relying on your memory in such a responsible matter is extremely frivolous.

Handle type lock mortise

This manipulation definitely deserves a separate analysis. Experts recommend playing it safe and sealing the end of the door, as well as its surface, with masking tape. This should be done to prevent possible damage. As practice has shown, it is much more convenient to apply individual marks on the tape. And it will also serve as a clearly visible boundary, which you absolutely must not cross during work.

It is recommended to install lock handles at a height of strictly 100 cm above the floor. This type of lock must always be supplied with a template. Therefore, there are no special problems in marking. Since cylinder mechanisms can be different in size, you need to look for a suitable crown only after purchasing the lock. When using a template, do this:

• it is bent carefully along the line of the door protrusion;
• applied from the end side;
• make marks showing the centers of the holes.

In these places a hole is drilled in the plane of the door. It is not advisable to pierce through it. As soon as the guide drill comes out from the opposite side, they pause and start drilling with a crown from the inside out. This approach is truly professional and avoids splitting the wood. Then it's time to prepare the holes for the latch.

At the same time, they work in the marked places with a 2.3 cm drill bit. You need to go to the previous hole. The drill is held strictly at an angle of 90 degrees to the door. Otherwise, there is a high risk that the latch will jam and work poorly. When the passage is ready, the latch is inserted into it.

Now you need to align the location of the element with respect to the edge. A pencil will help you trace the outline of the decorative frame. Next, removing the latch with a utility knife, cut the canvas along this line. When this work is completed, using a chisel, select a secret cavity, which should be slightly smaller in size than the latch frame. You cannot clean out the cavity initially; this may result in damage to the film with a chisel.

Having prepared the groove, return the product to its place, tightening the latch with self-tapping screws. The holes for them are drilled in advance with a 2 mm drill. If the part moves slowly, you need to trim the contacting places. The assembly of the handle itself is done according to the manufacturer's instructions. It is imperative to pay attention to how the tongue is positioned (normally it always faces inside the room).

To learn how to embed a lock into a wooden door with your own hands, watch the following video.

Installing a lock on an interior door will increase the comfort of your stay. This is very convenient, as it allows you to limit a small child’s access to those rooms where he could disturb adults or get injured. Embedding a lock is quite easy; almost any homeowner can do it.

• The lock itself, with a set of handles and bolts
• Square and pencil
• Drill
• Core drill, 5 cm in diameter
• Spade drill with a diameter of 23 mm
• Chisel
• Screwdriver or screwdriver.

Having a full set of tools will allow you to complete all stages of the work quickly and accurately. If something is missing, it is better to ask friends or acquaintances for a tool than to try to do without them, as this will lead to poor quality work and unsatisfactory appearance.

Marking

Usually the handle is located at a height of about a meter from the floor, so it will be convenient for use by people of any height. Therefore, we measure 95 - 100 cm from the bottom edge of the canvas and make a mark. Then, at the selected level, using a square, we mark the centers of future holes. On the end plane the center of the lock will be in the middle, and on the side plane it is necessary to retreat 6 - 10 cm from the edge. This is the place of the future lock and handle.

Lock drilling

Drilling holes for the lock starts from the end. A feather drill is installed in the drill and a hole about three centimeters deep is drilled exactly at the marked center. This is the place for the lock tongue.

After this, a core drill with a diameter of 5 centimeters is installed in the drill. Use it to drill holes on the sides. If you are not sure that you will be able to drill the hole horizontally, without distortion, then you need to mark it and drill on both sides. In this case, the drilling depth is equal to half the thickness of the door. If everything is done correctly, you will get a round through hole with a diameter of 5 centimeters, which has a side hole with a diameter of 23 millimeters.

Before installing the lock, you must cut out a recess for the latch. To do this, the lock is inserted into the door and the latch plate is outlined with a pencil. Along this contour, using a chisel and hammer, a recess with a depth of approximately 3 - 5 mm is selected, depending on the thickness of the plate. At the same time, a recess for the tongue is cut out on the door jamb according to the size of the special trim. This is where the lock tongue will go and hold the door closed. When both recesses are ready, the lock and recess are fixed to the jamb using the self-tapping screws that usually come with the kit.

Installation of handles

The further process does not cause any difficulties. The handle with screws is put into place first. The screws are unscrewed and the handle is inserted into the lock. To do this, the handle has a special square-section rod, which passes through the corresponding hole in the lock. After that, a second handle is put on this rod on the other side and secured with screws. Then decorative overlays and the handles themselves are put on. This completes the installation process.

After this, all that remains is to remove the debris and tools.

Useful notes

Even if you are confident in your abilities and know how to drill, it is better to work with a core drill from both sides. This will ensure a neat cut and there will be no chips or burrs on the surface of the door that will spoil its appearance.

It is better to drill a recess for the lock in the end of the door after the hole for the handles has been drilled. This way you will be sure that the hole is completely connected to the main one. Otherwise, you may need to drill out a hole for the lock.

When choosing a recess for the lock plate, work must begin with the outline. The entire contour is outlined with gentle blows, and only after this the wood is selected. This will prevent chips and cracks from appearing.

Do not over-tighten the screws on the handles. The fixation should be tight, but not excessive. Otherwise, dents may appear on the surface of the door, spoiling its appearance.

Installing doors in a doorway is a task that requires prudence and accuracy. But this door will not close without a lock. It cannot be opened without a handle. Embedding a lock into a wooden door means protecting yourself and your property from strangers, keeping you warm in the winter, and making the interior more interesting.

Mortise lock in a wooden door

How to install a lock on a wooden front door? To do this, you first need to prepare. Wood is a material that can be easily finished, but it requires experience working with wood flooring. You should know the type of wood and its abilities. To install a lock in a door you need:

The work involves stages that should be performed sequentially. If you don't follow certain, simple rules, the lock may stay in place, but will it work?

A selection of locks for wooden doors

Before choosing a lock, you need to answer questions about the lock:

Door locks are divided into types - rack, code, electronic, cylinder, lever. The rack lock is a simple design that is easy to break, you can break it yourself, and has a primitive appearance.

Cylinder lock – inside the lock there are cylinders located at different heights. If the element is not in its position, the lock will not open.

When forced, the lock is drilled or the core is knocked out. But, manufacturers add special elements to the lock material, against which the drill bit breaks. Such a lock has a long service life, is easy to change, and may have special plates, which are also a barrier for a burglar.

This is what a cylinder mortise lock looks like

The lever lock is a reliable design. This type of lock is practically unbreakable. To open without a key, a professional uses 2 master keys. Inside the lock there are levers that are driven by a key.


Combination lock – to open the lock, you must enter a specific code. This lock cannot be installed on a wooden door.


Electronic lock – does not have a keyhole. It has one button to open, which is located indoors. To open without a button, there must be a signal from the side.


Once the issue of the lock has been resolved, you can begin to assemble the necessary tools.

Tools for cutting a lock into a wooden door

In order to embed the lock into the door, you will need to make a groove for the lock. After which the mechanism is installed. To do this you will need a cutting tool:

Set of tools for inserting a lock into a door

All these tools will be needed to install a mortise lock. To install the overlay mechanism, you will need a slightly different set of tools.

The process of making a lock groove

Before embedding the lock into the door, you need to take measurements and markings to cut out the groove. The instructions for the purchased lock indicate the different distance at which the handle should be located from the lock. This distance ranges from 95 to 100 cm, but many craftsmen correlate this distance with the height of the people living in the apartment or house. The taller the person, the higher the castle should be.
Making a groove for a lock:

1. Let's say the height is 95 cm. It should be measured from the floor up.

   

   Distance to the lock from the floor

2. Next, you need to take the lock and place it in the place where the mark is placed, with the side that will be attached to the door. The lock mechanism needs to be outlined with a pencil.
   
   
3. The hole for the lock is cut along the marked lines with a feather drill, the width of which coincides with the width of the lock bar. There are 2 methods for cutting the groove here. First: carefully, slowly move the drill inside the door 2 cm to the mark. Second: immediately drill the desired groove.
4. The cut hole should be slightly larger than the width of the locking mechanism (by 2mm). This will allow the lock to enter the door calmly (without the use of physical force).
5. You need to level the edges of the hole with a hammer or chisel.
6. After this, you need to insert the lock into the resulting groove. It should enter the nest without hindrance.
7. Next, you should mark the holes for the lock strip. To do this, you need to attach it to the door and circle it with a pencil.

   

   Marking the holes for the lock plate

8. Using the markings made with a chisel and hammer, a recess is made, the depth of which is equal to the thickness of the plank. There is no need to make the notch larger, but you also can’t make it smaller.
   

After the work has been done, you need to carefully and carefully try on everything. If there are any errors, they should be carefully removed with a sharp knife or chisel. So that nothing interferes with the insertion of the locking mechanism into the door.
When working with a drill, you need to keep the tool level. If the work is done at a degree of inclination, then the groove may be uneven.

If the purchased interior door is not equipped with a lock, you should figure out how to install it yourself. This will not only save money, but also carry out all the work efficiently. Before starting installation, you should understand the instructions and the choice of locking mechanism. It is worth considering that the thickness of the timber from which a standard wooden structure is made must be more than 40 mm. To figure out how to embed a lock into an interior door, you should get acquainted with the features of the process.

Features of locks

There are several common types of locking mechanisms that can be installed on interior doors. Some of them are equipped with handles, others come separately. Independent locking mechanisms are installed in this way - first the lock is cut in, and then handles are installed on both sides of the leaf.

Also, instead of a full-fledged lock, you can choose simple handles with small locking devices (latches). They have a simple design, but the work of installing them is a rather complex process. For installation you will need to have special tools.

After purchasing the lock, you can begin installing the structure. It fits in quite easily. You can do the work yourself. The procedure is not very complicated. You should not rush during the work process.

Typically the handle is located at an equal distance from the floor and the top of the doorway. Therefore, before installation it is necessary to measure 1 m from the floor and mark it. After this you will need to use a drill. A hole for a lock must be provided at the end. The drill must have a diameter that is equal to the thickness of the locking device body. The depth is determined by the length of the locking device.

Then, at the end of the door leaf, you need to mark the location for installing the support plate. To do this, the contour of the part is applied to the wooden product. First, you need to make a hole with a drill in the place where the door handle will be installed. Drilling must be done with great care.

When the drill appears on the other side of the blade, drilling must be stopped. Then drilling is carried out on the other side. Some craftsmen drill right through the canvas. However, this technique can easily damage the canvas.

After this, a lock is installed on the product, and the places for screwing in the screws are also marked. In the marked places it is necessary to make holes into which the fasteners will be screwed. To understand how to insert a lock into an interior door with your own hands, it is worth learning about attaching the handle and the features of working with doors made of different materials.

Handle attachment

To install the handle, you must first install decorative overlays on each side of the canvas. Once they are secured, you can place the handles in the prepared holes.

First, the rod is fixed. It will become the connecting element between the door handles. The length of the latter is measured using a ruler.

You must attach the receiving pad to the resulting marks, and then trace it with a pencil. You can drill holes along the contour and use a chisel to bring it to the required shape. Next, the overlay is installed.

Important! After installation, you should check how the lock opens and closes. If necessary, you can bend the tongue of the lining.

This algorithm for installing a lock is more suitable for wooden structures. It is easy to embed a locking device into it, choosing any place on the door. If the canvas is made of metal, you will need to perform the work using a special algorithm. Sealing elements should be installed between the frame and the door.

Differences between MDF and metal doors

Products made from MDF are easy to install. The work does not require specific skills. You also don't need to study editing theory. A basic knowledge of the installation procedure is enough. The block inside the door is located at a height of 1 meter above the floor.

If you do not have enough experience to install such a structure, you can damage the product when trying to install the lock. Therefore, the installation of locks on interior doors made of MDF is usually carried out by specialists who have extensive experience and special skills.

The insertion of a locking mechanism into metal structures is carried out only by professionals. If you try to install the lock yourself, you can seriously damage the structure. Such an attempt may result in a damaged door leaf and a broken lock. As a result, you may need to install a new box.

Inset using a router

A hand router is used for quick installation of locking devices and hinges. This device has many differences. Some believe that the router is a fairly large and difficult to control mechanism. However, the manual device is quite compact and also extremely convenient to use.

Using a router, niches are prepared for locks and hinges. How to cut a groove for a lock using a router? To perform such work, you must use a standard set of tools.

To install a lock on an interior door, you will need to complete the following steps:

• The door leaf is secured vertically in a side position using a slipway. This is necessary so that during installation there is no need to hold the door structure.
• Now you need to mark the place for the tongue.
• Try the lock on the canvas so that the drawn line is in the center of the drilled hole for the tongue. After this, you should mark the bottom and top edges of the bar and the lock.
• Using a square, you need to draw straight lines at the end of the door.
• We insert another cutter into the device, which will fit the dimensions of the plank. After this, a hole is made in the center of the marked area.
• Wood is then drilled into the door and then knocked out. You need to insert a lock there and then install the handles.

If you don’t have a router, you can get by with standard tools. In the process of this work, a neat hole is made into which the locking mechanism will be placed. In addition to repairing and inserting locks, you may need to completely replace the locking mechanism. How to disassemble the lock of an interior wooden door? If the door is made of MDF, the process will be quite simple. The main thing is to accurately select a lock that will fit the dimensions of the already created recesses.

As you can see, installing a lock on an interior door is quite simple. To work, you will need to have a milling cutter or a standard set of tools. Special care must be taken when installing the lock. It is necessary to carefully make a recess in the door leaf.

In order for all the work to go quickly, you should carefully prepare for installation - collect the necessary tools, select materials. You should also take into account the basic rules when working with wooden structures. For example, you should not drill a hole for handles right through. It is better to do them on both sides.

Do you want to have your own space and be sure that no one will break into it? Then installing a lock on your interior door is the only right decision for you. You can do this yourself, without resorting to outside help. It is only important to choose the right accessories. It must be of high quality, match the interior in shape, color and design.

Choosing a lock for an interior door

Based on function and design, there are several types of door locks:

• regular latch or halyard lock;
• latch with lock;
• mortise;
• magnetic;
• overhead;
• latch;
• latch;
• level

This is the most primitive type of lock, which is used in almost all interior doors. It is a simple design consisting of a cylinder and a plastic or metal tongue. Often such a mechanism is mounted together with a handle that controls the tongue.

The latch is the simplest mechanism installed on interior doors

The purpose of a halyard lock is to keep the door closed. A conventional latch is simple, reliable in operation, and characterized by a wide range of designs. However, due to the overly simple mechanism, it has not found widespread use.

Locking latch. It is considered a variation of a regular latch, which is equipped with an additional latch. It blocks the movement of the handle. There are two types: lever and push-button. The first type is more practical and reliable. A push-button lock is no worse, but it can cause such an unpleasant situation as accidentally slamming the door.

The latch with a lock has a number of advantages: simple installation, simple design, wide selection of models. The disadvantage of this type of lock is its weak locking mechanism.

When purchasing a product, pay attention to whether the movements of the tongue are smooth and whether the spring returns it inside the door.

It was popularly called a mechanism with a key cylinder. Outwardly, it is similar to a lock for street doors, but has a simpler design. The device includes a cylinder and a lock block.

Mortise locks are reliable and durable

There are two types of cylinder: “key-key” and “key-turner”. The first is installed if the lock is used occasionally. The second, on the contrary, is suitable for more frequent use.

Mortise locks are used to close bedrooms, offices, and storage rooms. They reliably protect against penetration, are durable, and rarely break. If we talk about the disadvantages of the device, then this includes the complexity of installation and the dependence of the device parameters on the thickness of the door.

If you can afford to splurge, then this type of lock is for you. It is intended primarily for rooms where it should be as quiet as possible: bedrooms, children's rooms, offices.

The magnetic lock is quiet, but its cost is quite high

Silent operation is ensured due to its design, consisting of a crossbar, a strike plate, a magnet, and a case for the magnet. The bolt is attracted to a strike plate with a magnet, which is located on the box.

Along with the advantages of the product, there are disadvantages. Firstly, this is the impressive cost of the castle. Secondly, the lock case is not very compact in size, which is why it looks bulky.

Rim lock. Products of this type can rightfully be called a rarity. However, despite this, the demand for it has not fallen to this day due to the simplicity of the mechanism and uncomplicated installation.

Current models boast a comfortable body. The device is mounted on the inside or outside of the door, thereby providing protection against unexpected entry.

The original purpose of the lock was to secure one of the double doors. Currently, it is installed mainly in the bathroom and toilet.

Espagnolette installed in bathrooms

The operating principle of this product is so simple that even a small child can handle it. Its installation does not require special knowledge and experience.

Latch. This is the simplest type of castle. A latch is a metal plate with a retractable lever. It is installed as a main or auxiliary lock.

The mechanism has become widespread due to its high degree of reliability and protection. It is used for both street and interior doors.

To fix the bolt in the mechanism, plates (levers) with grooves of various shapes are used.

Level lock has a high degree of security

Each insert has a corresponding key bit profile. The lock will open only when the levers are in the correct position and the groove is free for the bolt to pass through.

If you have made your choice in favor of a stylish but simple lock, you can get to work.

Tools and materials

To install the mechanism you will need the following materials:

• handles of any shape (round, in the shape of the letter “G”) – 2 pieces;
• cylinder mechanism with spring;
• fastening screws that connect the cylinder mechanisms;
• crossbars;
• sockets for closing cylinder devices – 2 pieces.

In addition to materials, the work requires a small set of tools:

• a simple pencil;
• roulette;
• drill;
• office knife;
• chisels at 0.1 and 0.2 cm;
• feather drill 2.3 cm;
• drill 0.2 cm;
• crown 5.4 or 5 cm based on the thickness of the door;
• masking tape;
• hammer.

If you don’t have any of the listed tools at home, you will have to buy more. Their cost is low, and they are always useful on the farm.

Lock installation

Installing the mechanism yourself will not be difficult. You just need to forget about the rush and be attentive enough. The success of the business depends on many factors, including the type of door.

The easiest way is to insert the lock into a piece of wood. It will be more difficult with a product made from MDF, since it already requires skills and knowledge. Therefore, in this case, it is better not to take risks, but to call for help from a master of his craft..

Otherwise, poorly performed work will lead to damage to the mechanism, which will require it to be repaired or even require a complete replacement of the product.

Preparatory stage

Marking is the initial step towards installing a lock. The first thing to do is to prevent possible damage to the door.

The lock is mounted at a distance of about 1 m from the floor

For this purpose, measure a distance on the canvas of 0.9 - 1.1 m from the floor covering - this is the location of the lock. Then apply masking tape in that place to the end and surface of the door. This procedure will not only protect your product from scratches, but will also make it easier to take measurements.

The template is sold with a lock included in the set. It allows you to accurately apply marks indicating the position of the holes. To do this, fold the stencil along the fold line and attach it to the end. Then use a self-tapping screw to mark the centers of the holes on the end and on the flat surface of the canvas.

Making holes for the handle and lock mechanism

After applying the markings, proceed to the following stages of work:

Mortising a lock with a router

A small vertical machine is called a milling machine. It is easy enough to use, so even a beginner can operate it. To embed a lock into an interior door using a machine with your own hands, you must:

• Place the canvas perpendicularly on its side and secure it with a slipway.
• Measure and mark for the tongue.
• Place the lock on the sash so that the marked line runs clearly in the middle of the recess made under the tongue. Trace the body of the product with a pencil, as well as the bar along the upper and lower borders.
• Draw straight lines on the end of the canvas. Use a square if necessary.
• Use the machine to select the opening for the lock.
• Change the cutter in the machine, based on the dimensions of the plank, and adjust the depth required for its thickness. Make a notch in the center.
• Make a socket for the lock case. To do this, draw a straight line in the middle of the marking.
• Drill holes on the resulting line with a drill. The wood that remains is removed with a hammer and chisel.

The opening for the lock can be made with a router

Thus, an opening for the lock was created. To check if everything is done correctly, insert the device into the seat.

Mortise a lock without a cutter

The absence of a cutter is not a reason to put off installing a lock until better times. To perform the installation, the most common tools that can be found in any home are suitable.

Although it should be noted that there are cases when you cannot cope without a professional machine. For example, installing a lock with a latch.

Mechanism insert with cylinder

Sometimes a lock is installed on a door that already has a handle. It is for such situations that mechanisms with a larva are designed. They have the shape of a rectangle, so this work will seem overwhelming for a self-taught master.

Locks with a cylinder are mounted in doors with an installed handle

However, you don't need any tools or skills. Only after trying, you will learn how easy it is to insert a lock with a cylinder into a wooden door.

To do this, find a place for the lock (above or under the handle) and undertake the following points:

• On the end part, draw a center line where the mechanism is mounted.
• Attach the lock and make marks indicating the height of the product.
• Drill holes along the center line with a small distance between them.
• Using a drill, remove the jumpers between the holes and make a neat socket that matches the size of the lock.
• Place the mechanism in the resulting opening, secure it with self-tapping screws. Using a utility knife, mark and cut out the perimeter of the locking plate to approximately the same thickness as the locking plate itself.
• Remove the mechanism and use chisels to make an opening for the device.
• Place the lock against a flat surface of the canvas and mark the location of the cylinder. Then outline the larva. Do the same on the back side of the door.
• Drill a hole for the larva. In order for the device to fit in freely, you need to go slightly beyond the contours of the markings.
• Place the lock and screw it with self-tapping screws, the holes for which should have been made in advance.
• Attach the cylinder and check how the mechanism functions. Place linings on it using self-tapping screws as decoration.

Installation of the lock mate

This is the final moment of installing the locking mechanism. To install the response part, follow these steps:

1. Close the door and draw two lines on the opening, the distance between which corresponds to the size of the lock latch.
2. Measure how far the beginning of the latch is from the corner of the door.
3. Measure exactly the same distance on the opening - this is the beginning of the recess.
4. If you are going to recess the counter part into the jamb, then install it in place and trace it with a pencil along the inner and outer contour. If not, then outline only the inner one.
5. Before installing the answer, use a tool to make indentations for the tongue and screws.
6. Install the striker and close the doors. If excess play occurs, eliminate it by bending the tongue on the response.

The lock mate is secured with self-tapping screws

Thus, you have come to the finish line. Installing a new lock or replacing an old one is not a very complicated process, but it requires care. When changing the previous mechanism, make sure once again that reinstallation is advisable. After all, the problem can sometimes be solved by simply adjusting the device.
