How to remove the lock from the door: disassemble the round interior door handle with a latch, the larva device, video. An easy way to remove a mortise lock

Pen - necessary element door hardware designed for easy door opening. Practicality door structure largely depends on the external aesthetic appearance, design features and functionality of this accessory. With constant use of the door, the handle, regardless of the material and type, often becomes unusable: it wears out, breaks. Therefore, in case of any malfunction, it must be repaired or replaced with another one. In order not to call the wizard, you can perform this procedure yourself.

Brief instruction about how to disassemble the doorknob will acquaint the reader with this simple process.

According to the installation method, there are 2 types of handles:

• invoices;
• mortise.

Overhead fittings are installed on the door leaf using a strip; for a mortise design, a hole in the door is required.

By appointment are:

1. input;
2. interior.

By functionality, door products are divided into 2 types:

• mobile;
• stationary.

Movable handles are available in 2 versions:

1. rotary (knobs and buttons);
2. pressure.

Parsing the door handle depends on its type and design features.

Design features

Stationary handles are produced without latches and locks. The elements of fastening to the door block are screws or self-tapping screws. Such fixed structures are decorative in nature, serve exclusively for the movement of the door. They can be 1 sided or 2 sided. different shapes connected by an axial element. They are installed on interior or plastic balcony door blocks, rarely - at the entrance.

Pressure products are 2 L-shaped levers, which are connected by a rod passing through the door block. In such a device, when turning, the fall tongue enters into inner part door and lock it. With the help of elements, external and are mounted.

The main advantage of the model is its reliability. The failure rate of pressure mechanisms is much lower than others.

Swivel mechanism most often performed in the form of a ball or button with a diameter of 50-60 mm with a lock located in the center of the round handle. The keyhole can have a 2-sided exit or 1-sided with a latch. The door opens with a simple twist. Such fittings may also contain a door lock. Therefore, they are often used in the door structures of bathrooms and interior blocks, and are also called knobs-knobs.

They are compact, easy to install, low price, but have such disadvantages as low strength and fragility due to jamming of spare parts inside the mechanism.

Rotary and pressure products differ in the shape and method of opening the latch.

Components of the mechanism

Rotary and push door products for interior doors have the following spare parts and parts:

• latch;
• strap or socket;
• decorative flange;
• fasteners;
• a special key for pressing and removing the mechanism.

Keyhole door hardware kit comes with keys.

Required Tools

To remove the handle interior door, you need to prepare the following tools:

1. drill;
2. pen drill;
3. cutter;
4. flathead screwdriver or screwdriver;
5. roulette;
6. marker;
7. chisel;
8. hammer.

How to withdraw

Dismantling door fittings is not a problem if there is necessary tools and minimum theoretical knowledge on the device of the mechanism. You can remove the door handle yourself, without calling the master. To do this, follow the instructions:

• Support and secure the door in a stationary position.
• Pry off the decorative flange with a knife and pull it back a little. Under it are fasteners that need to be unscrewed.
• On the decorative flange of the pressure device is a spring-loaded locking pin. Push it in with a screwdriver. In rotary models, the pin is located inside the housing. In order to get to it, insert a wrench or an awl through the technological flange hole. If the pin is not palpable, rotate the flange until it contacts it.
• Press the pin, pull back at the same time door device.
• Loosen the fixing screws.
• Separate the inside of the door element from the outside, remove the handle and decorative flange.
• If you need to remove the latch and replace it or repair it, unscrew the screws that fix it on the side door block, remove the bar, then the mechanism.

When installing accessories in another place, it is not worth disassembling it for spare parts. It is attached to the door structure in the reverse order. If the handle or latch is to be repaired or replaced, further disassembly is carried out.

How to disassemble a door handle

The replacement of the door handle is carried out in order to repair it due to breakdowns, wear, in the presence of scuffs, scratches, to improve appearance, as well as with a complete replacement of the door unit.

Before starting work, the type of mechanism, its features, are established. one model with simple device are easy to disassemble, and some have more complex elements, such as latches with latches. It is difficult to carry out such work. Therefore, it is necessary to consider the replacement of each type of door hardware separately.

Round

To disassemble a round door handle or knob, you must follow these recommendations:

1. Use a hand tool to pry off the decorative flange or escutcheon with a simple keyless swivel lock.
2. With an awl, nail or special key, press the opened stopper.
3. At the same time, gently pull the handle and remove it.
4. On the side of the removed part, unscrew the bolts from the mounting plate and disconnect it from door leaf.
5. Unfasten the cylindrical mechanism, the latch.
6. Remove the screws, detach the tongue.

If there is no need to change, it is rearranged. It happens in the following way:

• Insert the latch so that the beveled part of the tongue faces towards the closing of the door.
• Fasten with 2 screws.
• Insert the part of the fittings with the key drum on the other side of the door structure.
• Attach the clamping part and fix with 2 screws.
• The handle should turn without jamming and return freely to normal condition.
• Correct it. To do this, you need to carefully hold one side and align the other.
• Attach decorative trim.
• Insert the rest of the handle.

The accuracy of installation and functioning is checked both from the side of the latch itself, and drum device with a key.

Stationary

The stationary product has simple design attached to the door with screws. Therefore, it rarely breaks down, and is removed only when it is necessary to change it for a more functional model.

To unscrew the fittings for the interior door, it is necessary to carry out the following actions:

1. look around door mechanism for the presence of an axle. To do this, hold the handle with one hand, turn it with the other.
2. If the mechanism is located on the rod, remove one supporting side, the second moves away on its own.
3. If the rod is not found in the handle, use a flat screwdriver to unscrew the screws holding the handle.
4. Remove it by gently pulling it towards you.

When unscrewing the mechanism, it is necessary to carefully hold it with your hand so that after removing the connecting screws, part of the product does not fall out of the connector and is not damaged.

For interior doors

In the pressure device, the process of disassembling it causes difficulties. This is due to the fact that the fittings are mounted on the axial rod and pulled together by a 4-sided.

To carry out the repair of the interior door handle, the disassembly of the push mechanism is carried out in 3 stages:

1. Remove the screws that hold the pad, remove the plugs.
2. Then it is necessary to loosen the fixation of the rod and separate the 4-sided square.
3. Remove the lining on the other side, the rest of the mechanism and the axial rod. After removing the parts, you need to pull the handle towards you.

The pressure product is ready for replacement or repair.

How to fix a pen

Often, door handle repairs are carried out in such cases:

• the mechanism does not return to its original position;
• the handle sticks, it turns hard;
• the tongue does not move when turning, pressing the device;
• the handle falls out without damaging the base.

Often the cause of these problems is wear, abrasion of the part during constant operation. Therefore, periodically it is necessary to lubricate the mechanism parts and the keyhole, clean it from dust and dirt. When lubricated door product scroll so that the viscous liquid is evenly distributed over the elements.

If the handle is loose, it is necessary to correct and tighten the fasteners.

Sometimes it is required to repair fittings in metal Chinese door. Products Chinese made from silumin they malfunction, break, and it is not easy to install a lock in such a door. Easier mechanism replace. The principle of operation is similar to replacing an element in interior doors.

In the interior

In the door handle for interior doors, repairs are most often made when the handle falls off. The base remains attached.

The reason is the use of low-quality fittings, as a result of which the retaining ring could break or fall off.

To carry out repairs, perform the following steps:

1. Unfasten the base from the door.
2. Examine the retaining ring. If it has moved, it is necessary to adjust its position and install. If the ring bursts or breaks, it is changed with the further installation of the handle.

The duration of the procedure is 15-20 minutes.

Repair of the door handle of the interior door is carried out if, after opening the doors, the fittings do not return to their normal position.

The cause of the malfunction is a breakage or displacement of the spiral.

To replace the spiral, the following work is carried out:

• remove the device;
• unfasten the damaged part, replace it;
• secure with a retaining ring from above;
• install the mechanism.

If the spring bursts, you can make it yourself from a small piece steel wire. Pre-wind it, heat it on fire until bright red and lower it into cold water.

Removal and repair of the lock

Repairing interior door locks is difficult. The causes of failures are different.

When using cheap low-quality door fittings made of silumin, a 4-sided pin may break. The solution to the problem is the purchase of a steel mechanism from trusted manufacturers and its complete replacement.

A common malfunction of locks is incorrect operation of the tongue. This is possible with a short pin. The square can move in the direction of the latch, press it, reducing the functioning.

Repair work locks are carried out in this way:

1. A long pin is bought, the length is measured.
2. With the help of a grinder, it is shortened to required size.
3. Then you need to disassemble the lock of the interior door.
4. The square is changing, door fittings are being installed.

When mounting the handle, the base must cover all the holes left from the previous mechanism.

A lock with a handle can be replaced or repaired even by a novice master who knows how to use improvised tools.

Despite improvements in locking mechanisms, the use of innovative technologies and ultra-reliable raw materials, they still sometimes fail. In this case, they must be dismantled in order to install a serviceable device in place of the broken mechanism.

In this article, we will talk about how to remove door lock . Consider the dismantling process locking devices two types:

• mortise;
• overhead.

There is no point in talking about them, because to remove them you just need to unlock the mechanism, pull the shackle out of the groove and turn it in any direction.

Removing the mortise lock

To begin with, let's consider how to remove door lock mortise type, since it is considered that its dismantling is rather difficult. We will try to convince you otherwise. To remove the lock, you only need a screwdriver (flat or Phillips, depending on the type of fastening screws used).

So, to dismantle the lock, it is necessary to unscrew all the fixing screws located on the bar at the end of the door leaf. If a lock is installed without handles and a fixed larva, then in this case it is enough to pry off the bar at the end of the door and pull out the mechanism.

However, in most, a larva is provided - the secret part of the constipation, through which it is locked and unlocked. To remove the larva, you need to remove the screw, which is also installed in the end part of the bar. It is much longer than conventional mounting screws as it goes through the mechanism of the device.

After unscrewing the screw, press on the larva (on either side of the door leaf). Usually it comes out without any problems. In some models, it has a certain protection, which can only be removed by setting the internal secret in a certain position. To do this, insert the key into the keyhole, slowly turn it until you find the position you are interested in.

Next, consider how to remove door lock mortise type, if it has handles. After all, handles can interfere with the dismantling of the lock, of course, if they are provided for by constipation designs. Handles are put on a through pin, usually square shape, and are attached to it with a special locking screw. Unscrew it and remove the handles, pull the pin out of the lock.

Another reason why the lock cannot be removed from the door may be decorative overlays, the screws of which are screwed through the door leaf directly into the lock body. If they are on the lock, unscrew the screws and remove them. This was the last possible obstacle on the way to the complete dismantling of the lock from the door leaf. Now you can pull the device out of the end of the door.

Removing the padlock

In this part of the article, we will talk about how to remove door lock overhead type. It takes even less time and effort to dismantle it than to remove a mortise device. All overhead models are screwed directly to the door leaf using conventional screws or self-tapping screws. To dismantle the device, you only need to unscrew the fasteners. After that, proceed to remove the plate that closes the keyhole. That's all! The lock has been removed.

Be careful!

As already mentioned at the beginning of the material, the main reason for dismantling the locking device is its breakdown. Therefore, when purchasing a new lock, pay attention to several main factors:

• burglar resistance class;
• durability;
• operational characteristics;
• the name of the brand that released the model you liked.

This will help you choose really high-quality locking mechanism, which will function properly for many years, saving you from having to look for information again, how to remove door lock.

We wish you good luck in dismantling the old constipation and choosing a new, high-quality model!

In order to better understand how to remove a door lock, you need to learn how to identify their types.

Consider how to dismantle each of the above locks.

latch lock

To disassemble this mechanism, you must first remove its part located on the front side of the door leaf. From the side where the plug is located, you need to unscrew the cap with decorative design. After that, you will be able to see the mounting screws of the device. They need to be unscrewed and the mechanism carefully released.

To remove the lock, you need to gently push through its inside, after removing the end plate. When replacing the lock, it will be necessary to remove the door frame response plate.

Lock with handle

This is a simple and fairly common version of locking devices. Such a lock can be made in the form of a simple latch, as well as a more complex device that requires a key.

Before you disassemble the door lock, you first need. This can be done by using a hex wrench or screwdriver to unscrew the side or bottom screw. Then you should remove the decorative trim and unscrew the fastener screws. After removing the handle with the axial part, access to the mechanism of the device will open.

To disassemble the lock, you need to unscrew 2-4 screws that hold the plate on the end part. Then you should remove all the parts and the tongue of the lock. To do this, just push them inward, and then get them out of the door leaf through the hole at the location of the handle.

The malfunction of the lock handle is common problem at plastic door. It can break or, due to wear and tear, become completely unusable. The handle of such a door cannot be repaired, it can only be replaced. To remove the handle from the plastic door leaf, you need to move the base plate, under which there are two bolts. After unscrewing them, the plastic door handle can be removed from the hole and replaced with a new one. After that, you should install the plate in its place.

Locks with a secret

In the entrance or interior door, a lock is often installed that has a more complex device and involves the use of a key. We are talking about cylinder and lever type locks.

To remove the cylinder mortise lock, it is necessary to remove its front part and release the plate from the end of the case. After that, you need to gently push the lock with a screwdriver or other similar tool to further remove it from the end of the door.

The lever mortise lock is even easier to remove from the door. To get it, you should also release the plate and move the mechanism to the edge of the door. If the lock protrudes at least 0.5 cm beyond it, the case can be picked up with your hands or hooked with a screwdriver. Work must be carried out carefully to avoid damage to the parts of the lock.

How to dismantle the front door lock

If on front door a padlock is installed, it is removed very simply. To do this, you will need to unscrew the mounting bolts on both sides of the mechanism. After removing the bolts, the lock will be removed without any additional manipulations.

When a mortise lock is inserted into the door, its removal can be carried out in two ways. One of them involves unscrewing the disk, which consists of two parts. After turning it 20 degrees and then separating it, you will see two fixing screws. Unscrewing them will make it easy to remove the lock from the door leaf. However, such attachments are rare.

According to another option, the lock is dismantled using a special rod. The lock has a small hole on the side of the button at the base of the handle. Insert a round rod like an awl into it and remove the handle. Further, as in the first case, the disk opens, but one-piece. It should be twisted carefully to avoid damage.

Also, the fixing bolts can be located in the area of ​​​​the crossbars with inside doors. All bolts should be unscrewed, released and removed the locking mechanism. If it moves hard, its edges can be oiled. After such a procedure, the extraction of the lock will be significantly accelerated.

Dismantling the front door lock

Understanding how to disassemble the lock, this work will not seem difficult. Everything here is really simple. It is necessary to remove the upper case, gradually pushing the bolt with the support mechanism. All small parts, including springs, are manually removed. At the same time, utmost attention is needed in order to remember the sequence in which the mortise lock was disassembled, which part and in what place it was originally. After all, if you need to assemble the castle, you will have to restore everything, relying on your memory. There are a huge number of locks, and each model has its own device features. To facilitate the work, you can even draw on a sheet of paper and subsequently navigate through it in the process of work.

To figure out how to remove the lock from the door, you should first study the existing types:

• Latch. It is installed only on the interior door and does not have a keyhole for entering the key. This type is used for bathrooms and less often for rooms;
• Latch with handle. This version of the locks is installed in the canvas of the interior door, and is used for a short closing. If you press the handle, the tongue of the mechanism will move away and the sash will open;
• Locking mechanism with a secret. Such locks are usually used for entrance doors, but are less often installed in interior doors (simple types).

Why do you need to remove the lock?

Consider the main problems in which you have to think about how to disassemble the door lock:

• Jamming mechanism. Over time, any equipment can begin to seize, especially if it is not looked after and lubricated in a timely manner;
• Unforeseen breakdown. Repair will be required if the life of the device has already come to an end. Well, if you can only get by partial replacement spare parts, and not install a new lock;
• Replacement with an improved model to improve home security;
• Lost key. In this case, the dismantling of the larva is needed to open the door.

Attention! Before carrying out repairs or assembling a new lock, it is worth practicing on the old one so that you don’t make mistakes on the “clean” version.

How is the latch removed?

When disassembling this option, first remove the parts that are located on the canvas, remove the plugs from the door. After that, the place where the mounting screws are located will become available. They are carefully unscrewed to pull out the mechanism itself.

How to remove a door latch? It is carefully removed from the canvas by unscrewing the end plate. When replacing, the counter plate must also be removed.

We remove the lock equipped with a handle

This version of the locking mechanism is most often installed in an interior door. It is made in the form of a conventional latch, but there are also more complex options that require a key to open.

How to disassemble the lock of this type? First, remove the handle by unscrewing the fixing screws with a special construction key or screwdriver. After that, remove the overlay, which served decorative element, and unscrew the fasteners. After the handle is removed, access to the mechanism will open.

Attention! To remove the mechanism, first remove the screws that hold the plate on the end. Only after that, all other parts and the tongue itself are removed.

Most often, this type of lock has a problem with a malfunction of the handle. Breakage may occur due to the fact that the handle has already served its purpose. Repair of this element is impossible, so the handle is replaced.

How to remove a mortise lock with a secret?

Such locks today are found in the device not only the entrance, but also the interior door. A key is used to open the mechanism. That is, we are talking about locks of a cylinder or lever type.

To remove the cylinder type lock, its front part is removed, thereby releasing the end plate. After this manipulation, using a screwdriver, the device itself is pulled out and removed.

The lever lock is even easier to remove. First you need to release the plate itself and then move the mechanism to the edge. Work must be done as carefully as possible so as not to damage the parts.

Attention! If it is not possible to remove the lock normally, then it will have to be knocked down. In this case, the castle will become unusable. But sometimes it is necessary to bring down the installation in order to install a new one.

Proper dismantling of the lock of the entrance structure

If the front door is equipped with a rim lock, it is easy to remove it. To do this, unscrew the mounting bolts on both sides. After that, the lock can be easily removed.

When removed mortise lock you can use a special rod in the work. The design itself has special buttons near the handle and a small hole on one side. A rod is inserted into this hole, which looks like an awl. And there you can open the installation without problems and damage.

How to properly disassemble the lock of the entrance structure?

If you understand the theory, then in practice, disassembling the castle is not difficult. You can do everything yourself, without the involvement of professionals. Today, many different mechanisms are used, and each of the models has its own characteristics. To make it easier to complete the task, you need to draw a diagram that will help in the process.

How the lock is disassembled in practice is shown in our informative video.

The front door of the house or office is broken, try to change it internal detail- a larva. You can do it yourself. How to pull out a faulty mechanism and in what ways you can open a jammed door - read on.

How to extract a larva to pick up a replacement for it

As a rule, the mechanism does not fail unexpectedly. Having noticed the first signs of a malfunctioning lock, hurry up to replace it in the near future, otherwise you will simply not be able to get into your home or work at the most inopportune moment. A fairly common reason that the door has stopped opening is the breakdown of the larva. This is a detail of a lock with a secret mechanism where the key is inserted. It looks like a cylinder connected to a mechanism - a set of pins that opens only a key specially made for it. The larva controls the locking mechanism, it is easier to change it than the entire lock.

Before purchasing a new part, remove the broken one:

1. Unscrew the fixing bolt at the end of the door that holds the lock mechanism in place.
2. After inserting the key into the well, turn it 10-15 °.
3. Noticing that the special flag of the mechanism no longer protrudes, pull out the larva. This can be done from either side: from the outside, by pulling the key towards you, or from the inside, by pressing on the mechanism. If the larva is equipped with a rotating lamb, pull only in its direction.

Attention! If the larva cannot be obtained, this is probably prevented by decorative pads for the lock. They need to be removed and returned to their place only after the replacement of the part.

How to choose and replace the larva in the door lock. Instruction

Having received a part that has become unusable, take measurements in order to buy an identical one. Pay attention to the following parameters of the larva:

• length;
• width;
• diameter.

These specifications vary as doors may have different thickness. In addition, the indicators depend on the manufacturer. It is better to give preference to the firm, the larva of which was already in your castle before. Pay attention to the location of the mounting bolt hole. It should be at the same distance.

Keep in mind that the larvae differ in the shape of the keys, as well as the number of grooves for them: sometimes 2, and sometimes 1 plus a special lamb, thanks to which the door can be opened from the inside without a key. The color of the larva is also important - it must be in harmony with the entire castle. If possible, take the extracted part with you to choose the same one. Otherwise, rewrite the parameters and select according to measurements.

Advice. Included with the larva may be a different number of keys. Decide how much you need so as not to leave one of the family members without a personal copy.

To install, follow the same steps as when removing the mechanism, but in reverse order:

1. Insert the larva into the castle.
2. Secure everything with a bolt at the end of the door. If it does not fall into the desired hole, move the larva and screw the part at the same time.
3. Check the quality of the installation by opening and closing the door with a key on both sides. It should turn freely, and the lock should not creak.

Attention! First check the operation of the mechanism on open door. If everything went smoothly, you can test the lock by closing the door.

It is also possible to replace the larva without a key - for example, if it breaks and a part remains inside the lock. To remove the chip, you need to turn the locking mechanism. There are 3 ways to do this:

• get the pins from the larva;
• make a hole with a 3 mm drill under the cylinder;
• having removed the lining from the door, look through the slot where the flag is turned. Drill out the entire body of the lock and remove the larva.

Which option is better to use? This needs to be decided on a case-by-case basis.

If the lock did not wait for timely repairs and let you down, leaving you in front of a locked door, there are several ways out of an unpleasant situation.

1. Try to get into the house through the window. Not suitable for apartments located in high-rise buildings.
2. Dismantle the entire structure, together with the frame. To do this, you need to remove the lining around the entire perimeter of the opening, frozen pieces polyurethane foam and saw through the places connected by welding with the help of a grinder. To apply this method, you need to have the appropriate tool at hand.
3. Also use the "grinder", but only for sawing the castle. This is fast, but in the future it requires the replacement of the entire input structure.
4. Call the rescue service or the company that installed the door. It will take time to call and work with specialists, and sometimes you may need documentation confirming your ownership of the house.

There are ways that allow you to open a broken lock with the least loss:

1. With a hairpin, paper clip or wire. Break the makeshift lockpick into 2 parts. Insert one into the lock and try to turn it while pushing the pins with the second part. It does not work with all types of mechanisms.
2. Screwdriver. Effective for a cross lock. Having unscrewed its top, drill a hole above the keyhole, insert a screwdriver and turn it.
3. Drilled out the lock cylinder. Not suitable for those designs that are equipped with powerful armor plates.

Advice. In order for the lock to serve properly, lubricate it regularly, do not insert foreign objects there. Do not slam the door to eliminate the possibility of its deformation or distortion. By following these rules, you will significantly extend the life of the locking mechanism.
