Door furniture - required element with rare exceptions, and even in this case we are not talking about its complete absence, but about invisibility. There are the most different types these accessories, however, knob door handles for interior doors can be called the most popular option.
Type of fittings
The appearance of accessories can be very diverse - from elegant Italian products to deliberately rough ones that imitate antiquity. More important is the design of the fixture.
Based on this feature, there are 3 main types of fittings.
- Overhead – or stationary. They do not include any locking mechanisms and serve only to open or close the sash. The shape of the accessory can be very diverse: U-shaped, round, sculptural. You can disassemble such a handle using a regular screwdriver.
- Push - turns on the locking mechanism. When you press the push lever, as a rule, L-shaped, the force is transmitted through a special rod and removes the latch tongue from the lock groove. In this way, the interior door is opened.
- Knob - have a round, oval or other three-dimensional shape, although in fact they are distinguished from other types of door fittings by the presence of a more complex lock, which allows you to lock the room from the inside. This option is very common in living rooms and hotels, but is also rare in apartments. The photo shows an elegant version of the accessory.
Accessories are made from the most different materials. Moreover, both the style of the product itself and the design of the fittings are important. So, for the pressure version, metal is most often used, less often plastic - the latter is too soft and fragile and, if pressed too intensely, quickly becomes unusable. The overhead model is made of wood, metal, and plastic.
For round model Metal and glass, both silicate and organic, are most often used. As a rule, glass is painted in different colors, form patterns and even an image in the depths of the object. No less popular is the option of combining metal with glass. This combination is especially effective with sculptural fittings.

The fittings, especially if we are not talking about an elegant product from Italy, but about a completely ordinary imitation from China, break quite easily. The fact is that for such cases no serious locking mechanism is provided, so this kind of product is made from fairly soft alloys.
Side handle interior space A locking pin holds it inside the sash. For smooth running, it is equipped with a spring. In fact, to disassemble and repair the lock, it is quite enough to press on the pin with a thin, sharp object. But, as a rule, the latter is invisible, so they act somewhat differently.

- First, remove all decorative trims that do not allow access to the mechanism. The linings are attached with ordinary screws, which are unscrewed with a screwdriver.
- Then, with a thin, sharp tool, like a screwdriver or an awl, press down on the locking pin and pull out the handle. The photo shows the removal of the knob.
- Then, at the end of the canvas, where the latch comes out, unscrew the bar. Usually a Phillips screwdriver is enough for this, but there are models that require a special tool.
- Use a screwdriver to pry up the bar and carefully pull out the latch.
How to repair a product depends on the damage.
Typically, springs become stuck or weakened, but other damage can also occur.
How to repair the knob handle of an interior door with various damages is demonstrated in the video.
The door lock has to be removed not only if it is replaced due to a breakdown. Like any other mechanism, the lock needs periodic cleaning and lubrication. The reasons for removing locks vary. You can call a locksmith to remove the lock, but you will have to wait. When you don’t have time to wait or don’t have the funds to hire a technician, you need to know how to disassemble an interior door lock yourself. It's not difficult to do. To do this, you need to know how to disassemble the most basic types of locks.

Stages of work: how to disassemble a round lock
Locks are installed on entrance and interior doors. Round handles with built-in locks have become the most popular recently. Their design has a halyard tongue, with the help of which the entire lock mechanism operates. Rotary knockers may have a built-in lock that locks the door. To parse round lock you will need a key. It comes with a lock included.
In order to find out why the handle broke, it is worth disassembling it and making sure what the reason is
If the key is not at hand or is broken, you can use any thin object to clamp the spring mechanism.
Steps to disassemble the nob handle and remove the lock:
- Clamp the spring mechanism;
- Move the pin;
- Pull the handle;
- Remove the pen along with the cap;
- Remove the flange latch;
- Unscrew the fasteners on the plate;
- Completely remove the handle (its two parts).
You need to move the pin using a key, inserting it into the hole located on the side of the handle. This must be done carefully. The lock is removed along with the handle, since it is built into it. This type of lock is mortise. It is also called round, since the handle itself has a spherical shape.
Disassemble the lock front door it will be more difficult. It can also have a round shape, but is built into the door separately from the handle. This one is more complicated than interior models. They are embedded separately from the handles into door leaf. Mortise locks can be a cylinder model. They work with the help of a larva, which is a fixator. You can remove the lock yourself. The cause of the breakdown may be the larva. You can replace the cylinder itself or change the entire lock.
How to disassemble an interior door lock: necessary tools
Many interior doors are equipped with handles that have built-in locks. Typically, such handles are installed on doors to a bathroom or toilet. Owners often save on fittings, so they install inexpensive ones. The locks in them can fail: the tongue gets stuck, the handle doesn’t work, the key gets stuck in the lock. You can solve these problems yourself. The lock must be accompanied by instructions for disassembling it. If there is no such instruction, then you need to figure out how to disassemble it and fix the damage yourself. You need to know the lock's structure in order to dismantle it.
The dismantling process may differ depending on the type of handle, but the entire process should not cause any particular difficulties
To work you will need:
- Screwdriver;
- Pliers;
- Adjustable wrench;
- A sharp object (awl, needle, hairpin).
Initially, you need to remove the cover from the locking button. After this, you can remove the mechanism itself.
Almost everyone has the above tools in their home. You need to act carefully so as not to damage the decorative trims, the lock itself or the handle. The work should be done calmly and step by step.
Five ways to open a door: interior locks with handles

After a careless emergency opening of the lock, it may need to be replaced. It will have to be removed from the door leaf and a new one installed.
Interior locks with a latch: causes of failure and analysis
The reason for the lock jamming or breaking may be: accumulation of dust in it, lack of lubrication, entry of a foreign object, or opening the mechanism with a key that is not the original one.
In order to open a lock of a simple configuration, you will need available tools that are found in every home.
Exists mortise lock with latch. Jamming can occur due to the tongue being stuck. The assembly of such a lock includes a spring mechanism. If it breaks, the tongue cannot move due to the spring.

When disassembling any lock model, it is worth considering its structure. It is necessary to follow the sequence of actions when disassembling the lock. It's easy to disassemble the mechanism, but it's still worth reassembling it correctly afterwards. By disassembling it slowly and carefully, after removal you can repair it and reinstall it. Sometimes the cost of a spare part for a lock is more expensive than the lock itself. In this case, it is easier to replace it completely and use it without any obstacles.
The locks on interior doors are the simplest to install. In essence, they come down to convenient additional constipation when door fittings and they do not fulfill the role of “burglary protection”. The design is very simple, so the desire to replace them and repair them yourself is quite understandable.
Disassembling the handle
How to disassemble the handle of an interior door, depending on its type.
Types of mechanism
All the variety of accessories can be reduced to 3 main types.
- Stationary - they are not connected to the lock, they are attached directly to the door leaf. Often they can have the most intricate shape, because in in this case their design does not affect functionality in any way. They are easy to dismantle: just unscrew the mounting screws.
- Push - this fitting is connected to a latch on a spring. Its role is to fix the sash in the closed state. When opened, the tongue is hidden inside the leaf and the sash opens. This device has a small decorative attachment with a diameter of about 30 mm, which is called a rosette. Such models are produced, for example, by company A
- Round or nob - represent one whole with a simple mortise lock. On the one hand, such a mechanism has keyhole for the key, on the other - a latch or button that blocks opening. The model is equipped with a round nozzle with a diameter of at least 50 mm. Moreover, quite often the sign that a lock is classified as a nob type is not the round shape itself, but rather the escutcheon and the presence of a lock.
Knobs have been very popular lately, so many companies, for example Palladium or Sirius, are producing them.
How to disassemble the round handle of an interior door
The procedure is quite simple and in order to disassemble the mechanism you will need the simplest tools.
- On the side where there is a button or lock on the knob, the decorative part of the handle is removed. To do this, use a screwdriver or an awl to press down on the stopper of the spring-loaded pin - it is located on the side, as a rule, and at the same time pull out the lining. The photo shows the dismantling of Sirius fittings.
- Then they find a recess on the flange - from below or from the side, and pry it off with the flat side of a screwdriver or the tip of a knife, and also remove it.
- The mounting screws are hidden under the flange. Since the decorative parts of the fittings have already been removed, there is nothing stopping you from unscrewing them. Remove the handles along with the pin holding them.
- At the end of the sash, unscrew the screws holding the bar, after which you can remove the latch.
How to disassemble the handle of an interior door is presented in more detail in the video. The assembly of such a product, for example, from Palladium, is carried out according to the same principle.
How to disassemble the handle of an interior door with a lock
You have to act somewhat differently when you need to dismantle push fittings with a latch, for example, from the Apecs company. It is not difficult to disassemble and assemble it, but there are more assembly elements, so the process will take a little longer.
- Here, first of all, the socket is unscrewed: the 2 mounting screws are unscrewed and the cover is removed. Then wrench or turn it with pliers door handle until swivel mechanism won't come out of it.
- The rotating device is removed along with the spring.
- Next, remove the washer, pry the spring with a screwdriver and pull it towards you.
- From the end side of the door, unscrew the screws holding the bar and the mechanism itself. Then the lock is pulled out of the hole in the canvas.
You can watch how to disassemble the door handle of an interior door in a video on the official Apecs website.
There are two types of broken interior door handles. Most often, when you press the handle, it simply scrolls, the door latch does not react to movement and the door does not open. Less often, the spring inside breaks, the handle sags lifelessly and no longer returns to the horizontal position.
Whichever option you encounter, to solve the problem, the door handle must first be disassembled and removed. The sequence of work depends on the design and features of the device of a particular model. Therefore, before we begin describing the technology for removing and disassembling the handle, let's look at what parts it consists of.
Door handle design
The photo below shows the design of the simplest door handle.
The first is the handle itself (in our case, a push handle). A plastic ring is attached to it, which ensures a tight fit of the handle to the base. It is also called a “rosette”, decorative flange or strip. There is a return spring inside it, which guarantees the stability of the horizontal position of the handle.
The next two elements are the travel stop and the locking ring. Their task is to prevent the handle from scrolling further than the required trajectory. All these components are sequentially located on the rod (Square in the image) and secured with a locking screw. The rod, in turn, is inserted into the locking mechanism and drives the latch.
The next photo shows the disassembled handle on the socket with a little more complex design some details.
Having understood the names and purpose of each of the elements, let’s move on to the sequence of removing the handle from the door and disassembling it.
Step-by-step instructions for performing the work
- First of all, remove the handle (indicated in the photo above). It is attached to the rod with a locking screw, or, in the simple case, is secured with a spring-loaded locking pin. We unscrew the screw with a screwdriver or a hexagon, depending on the shape of the groove on it. If we are dealing with a spring-loaded pin, then you need to press it inward with a nail and forcefully pull the handle away from the door.
- By removing the handle, we gain access to the socket. If the mounting screws are visible on the socket, then by unscrewing them we can immediately remove it from the rod. But more often there will be a special overlay on top of the fasteners (a decorative flange - in the photo above it is labeled as a socket). It will have a groove where it meets the door, by which it can be pryed with a screwdriver and removed. Perhaps the trim just needs to be turned counterclockwise if it is held on by the thread. By removing the decorative trim we gain access to the mounting screws that secure the socket itself. Since access to them is open and nothing is in the way, they will be easy to unscrew with a screwdriver.
It happens that the socket, just like the handle in other designs, has a hole in the end: there is a spring-loaded pin in the recess. In this case, to remove the socket, you need to press on it with a nail, while simultaneously pulling the socket off the rod. If you find a hole, but there is no pin in it, this means that when installing the handle, the socket was turned around its axis and the pin is located somewhere else. You can find it by smoothly turning the socket with a nail inserted into the recess until the nail rests on the pin.
After disassembling the handle in the suggested sequence, you will be able to determine the exact design of your particular model. And based on its characteristics, draw conclusions about what exactly caused the breakdown and how to fix it.
Types of handles for interior doors
Door handles are sold in two types: “knob” and “rosette”. The handle of the knob is usually hollow and light, while the handle on the rosette is made of more massive materials and is usually non-hollow inside. Over time, when the spring mechanism wears out, the first structure may begin to wobble or even sag. The second is that it will last longer and be more comfortable to use. Accordingly, their prices differ: most budget options— these are knob handles.
The shape of the handles is divided into rotary And push. The push button has classic shape handles: when you press it, the door latch is hidden in the lock body and the door opens. The rotary handle has a ball shape, which makes it less noticeable. In addition to the difference in design, these two designs differ in features that are not obvious at first glance.
The rotary handle is more compact: it is more difficult to accidentally touch it when passing by the door. And if this happens, it will not be as painful as with a push handle. At the same time, using a ball-shaped pen every day with wet or oily hands from cream is very inconvenient - your hands slip. So, if used regularly on kitchen or bathroom doors, lever handle will create less difficulties for you.
For repair, replacement or reinstallation in the opposite direction (often such handles are equipped with a drum on one side locking mechanism turnkey) round door handle you need to disassemble it.
You will need
- Phillips and flat-head screwdrivers, a special key with a stop for assembly and disassembly (included with the handle)
Instructions
1. Pry up flat screwdriver and remove the handle trim from the handle-side latches with a simple, keyless, twist lock. Using a special key or other sharp and thin object, press the opened stopper. Pull the handle simultaneously. Take it off. Using a flathead or Phillips screwdriver, unscrew the 2 screws on the side removed handle. Remove the untwisted halves of the handle from the door. Unscrew the screws securing the latch and remove it from the door.
2. To rotate the handle, install it in the door in the reverse order. First, insert the latch with the beveled side of the tongue towards the door closing and screw it with 2 screws. After this, insert the half of the handle, which contains the drum mechanism for the key, on the desired side of the door. Insert the clamping part on the opposite side and tighten it with 2 screws. Make sure that the handle turns easily and returns to its original position. If necessary, center it by moving it slightly from side to side. Put on the decorative trim. Insert the remaining part of the handle onto the clamping part screwed to the door. Make sure that the square tube with the flat plate fits into it. To do this, turn the handle lock handle so that the slot in it fits with a square recess in the same location as a square tube with a flat plate.
3. Put on the handle. When it rests against the stopper, push it down by pressing across the axis of the clamping part. After this, push the removable part of the handle completely onto the pressing part until it stops. Align the groove and push the decorative trim all the way. Check the security of the fixation. If necessary, lightly squeeze the fixing marks of the decorative overlay. Check the accuracy of the handle rotation lock on both sides: both on the side of the simple lock and on the side of the drum mechanism with a key.
