In this article we will deal with the topic of how to disassemble a door handle. Let us first consider the classification of this door accessory, outline the technical and design features of each model, and then proceed directly to the process of disassembling and repairing it.

Classification of door handles
There are several criteria for separating handles, which are based not only on the design features of the device, but also on the principle of operation. So, the first group is the differences in the installation method. There are two positions here:
- mortise models;
- invoices.
It is clear that the first one cuts into the door leaf, for which a hole must be made in the latter. The second is simply attached to the door using self-tapping screws or self-tapping screws.
The second group is the purpose of the door accessory. There are also two positions here: entrance and interior. That is, the first are installed on the entrance doors, the second on the interior doors.
The third group also defines two positions that differ from each other in their functionality or, more precisely, in their operating principle. There are also two subgroups: rotary and stationary. The former have their own additional division, a kind of subgroup, which again has two positions:
- push-type handles;
- rotary

It is clear that when the question is raised of how to disassemble the door handle of an interior door or entrance door, it is necessary to take into account the design features of the device. And they correspond to the type of products offered, the classification of which is indicated above.
Therefore, to make it clear what design features we are talking about, we list them, referring to some models of door handles.
Design features of door handles
Let's start with stationary ones. They are produced without any additional elements. That is, there are no latches or locks in their design. This is the simplest option. They are simply applied to the door leaf and secured through the mounting holes with self-tapping screws.
Such handles have only two purposes: moving the door and filling it decoratively. Therefore, manufacturers today offer a huge range of them in terms of sizes, shapes, and colors. They can be one- or two-sided. The latter are connected to each other by the so-called axial element. As for the doors on which they are installed, these are interior or balcony doors. Stationary handles are rarely mounted on entrances.

Now about push models. Purely structurally, these are two L-shaped levers. They are connected to each other by a steel rod passing through the door leaf. The design of the product contains a tongue that locks the door by entering the hole in the door frame located opposite the end of the leaf. Such handles are used on both entrance doors and interior doors. Push-type models have a large number of advantages, where we would like to highlight a long service life and high reliability.
The next type is rotary. More often, manufacturers make such pens either in the form of a ball or in the form of a button. The diameter of the device is 50-60 mm. There is a keyhole in the center. It can be located on each handle or only on one, that is, on a certain side. The model received its name only because the door can only be opened by turning the handle around its axis. Manufacturers often equip this rotary accessory with a lock. Such models are usually installed in toilets and bathrooms. Let us add for information that such handles are called “knobs”.

Unfortunately, it should be noted that rotary knobs have low strength and service life. The reason is a large number of rotating parts that wear out quickly.
I would like to separately list the components of the rotary and pressure devices, so that in the future it will be easier to understand how to disassemble the handle of an interior door. The pen contains:
- latch;
- socket, also known as a bar;
- square pin;
- a decorative flange that covers the mounting points;
- a spring with which the handle returns to its original position;
- a limiter that limits the movement of the handle when it is pressed;
- retaining ring;
- fasteners.
The devices are additionally equipped with a key, which is used to press and remove the mechanism, as well as keys used to remove and install the handle on the interior door.

Installation process
Let's say you installed a new interior door. Now you need to cut the handle into it. Its functioning depends on the quality of the operating mechanisms and correct installation. Before talking about the installation process, we suggest you familiarize yourself with its components.

How to properly remove the handle
So, let's move directly to the main topic of our article. But before that, I would like to point out that it is not always necessary to remove a door accessory in order to bring it into proper technical condition. Sometimes the handle just gets loose and needs to be fixed. To do this, press out the decorative flange with a knife or screwdriver, after which it must be turned. The fasteners will open and are tightened with a screwdriver. But if the task is to remove the handle, then the fasteners must be unscrewed after opening the flange.
Purely structurally, push and turn handles consist of two main elements. This is, for example, an L-shaped handle, which is a separate element. And the second is the same handle only with the axial part, which is an integral part. Therefore, after the fasteners have been removed, the handle is removed from the pin. In this case, the second handle with the axial part must be held with your hand. After which she is pulled out of the door leaf.
There are other types of handles in which the pin is a separate element. Disassembly of these models is done in exactly the same way. The only difference is that both handles are removed at the same time, and the pin is pulled out separately. After which the decorative strip located at the end of the door leaf is dismantled. It is secured with two self-tapping screws. And only then the lock itself is pulled out from the end of the door.

The rotary handles are removed almost exactly the same way. But they also have their own nuances:
- First, the ball knob, which is a separate element from the entire lock, is held on the pin by a small spring-loaded pin. Therefore, to remove it, you need to press on this pin with the key that comes with the door lock.
- Secondly, when you remove the ball, you will find a bar underneath it, secured with two screws. They need to be unscrewed. After which the opposite ball can be easily removed.
The lock itself is removed in the same way as in the case of overhead models - through the end of the door leaf. Please note that the height of the door handle, here we mean the height of its installation, has strict standards that take into account the ease of use of this device. Therefore, you should not rearrange them higher or lower, of course, unless you have some physical abnormalities.
Purpose of the latch
Today, there are a large number of models of similar products on the market, which in terms of design are noticeably different from the first examples of these mechanisms. However, both of them still provide their main function , which boils down to holding the sash in a closed, but not locked, position.
The owner can appreciate this option in the case where an interior door separates a heated room from an unheated one. If the interior door fits as tightly as possible to the sash, this will help minimize heat loss and better protect against the penetration of extraneous noise. This element will also be very useful in the summer months, when the temperature rises to critical levels: if the room is sufficiently well insulated, the air conditioner will take less time to create a comfortable thermal regime in it, for which it will not need to increase the intensity of operation .
You should also pay attention to such an important point as the risk of injury. There are often situations when a draft causes an interior door to open randomly, which can cause injury to a child or adult. If there is a handle with a latch in the design of the interior door, this is excluded. It is also important that this accessory is not able to change the appearance of the interior door , since it is carefully disguised.
Reasons for renovation
Before disassembling the interior door lock, it is necessary to identify common defects in the device:
- it is necessary to make significant efforts to lower the L-shaped handle or turn the ball, this is the so-called jamming of the door handle;
- the handle does not return to its original position, here the reason lies in the spring, which is better to replace;
- the latch comes out and enters the lock with difficulty - disruption of the operation of the bolts that move the latch;
- the handle has moved away from the door leaf and has become loose, this is not always a weakening of the fasteners, sometimes it is a consequence of the weakening of the entire mechanism;
- tongue jammed.
Useful tips
- It is first necessary to carry out careful calculations and then carry out any actions.
- When creating a through hole, you should be extremely careful and do not drill the door on only one side. This can cause chips on the back side of the door leaf. As soon as the drill begins to appear, passing through, you need to continue working on the other side. After completing the installation, it is necessary to double-check the tightening force of the bolts or screws used so that poorly fixed parts do not soon damage the handle.
Door handle repair
Let's move on to the next question - how to disassemble the door handle of an interior door with a lock. Where to start is by identifying the defect that has appeared, which reduces the quality of the device. Most often this is either a loose keyhole or wear on the rotating mechanism. In any case, the lock will have to be disassembled. How it's done:
- first of all, you need to remove the retaining ring; this can be done by picking it up with a screwdriver;
- then the torsion spring and key washer are removed, it is the latter that often breaks, or rather, the edges of the recess for the key are cut off.

Before drilling holes in the canvas, it is removed from its hinges. It is easier to work on a flat surface.
Depending on the material of the canvas, the height at which the lock with handles will fit is selected. If in a wooden case it can be secured with a latch in any place, then for MDF or chipboard - at the level of a meter from the floor. A wooden beam is specially provided in the canvas in this place.
Prepare your tools:
- door with wood drills and crowns;
- hammer;
- chisel (preferably the whole set);
- carpenter's knife;
- screwdriver;
- corner;
- pencil;
- awl.
Installation of the strike plate
Close the door and mark on the end of the door frame the place where the latch tongue rests. Using a feather drill, make a hole for it. A chisel will help you choose the required depth. Attach the mounting strip and screw it with self-tapping screws.
Ready! On average, installing a latch handle yourself takes 20–30 minutes. The main thing is to take your time, study the manufacturer’s instructions and the dimensions indicated there. Then everything will work out perfectly the first time!
It is worth mentioning separately about the installation of the so-called handle on the socket. Its internal mechanism is impressive in size.
- A nest is made for it at the end of the door - first drilled, then expanded with a chisel to the required size.
- The mechanism is placed inside the door leaf for fitting.
- Make recesses for the lining on the end part.
- Next, the location of the hole and handle square is marked on the surface of the door leaf - holes are drilled.
- The latch mechanism is inserted inside and secured with self-tapping screws.
- After this, handles are attached to both sides of the door.
- The strike plate is attached according to the same principle as when installing a knob-type latch handle.
