In the process of repairing an apartment, the question of replacing an old door structure often arises, since this product acts as a central element of a living room, bedroom or other room. When choosing an interior door, it is necessary to pay attention not only to the fabrication material and the external design of the canvas, but also to the quality of the fittings.

Now on the market you can find a large number of door locks of different configurations: from simple metal to decorative elements in bronze. Door locks for interior doors perform not only their direct functions, but also are an excellent design solution.

Types of locks for interior doors

If you are only planning to dismantle the old interior door and install a new one, then before going to the store, study in detail all the types and features of the castle products.

Depending on the scheme of operation of the mechanism, locks for interior doors are divided into four groups:

  • locks with latch (often the latter is made of chrome);

  • locks with key locking (installed in rooms where it is necessary to restrict access - office, workshop or bedroom);

  • Mortise locks for interior doors with an additional built-in lock;

  • magnetic locks (the principle of operation as a magnetic latches for cabinets).

Each of these types has its own advantages and disadvantages. However, the most popular are mortise models. They have a long service life, high reliability and ease of operation. There are several options for mortise locking mechanisms: plumbing, cylinder, magnetic, ball or roller. Below is more detailed information about these products.


This is a standard locking system, which features a lock and a special latch (locking the door from the inside). Such a model is often used in bathrooms, in the kitchen or in the toilet. Some manufacturers produce products with a comfortable wooden or plastic handle, as well as a two-piece retainer, inside wrappers and a slotted washer on the outside.


These are lock systems with door closing inside and out. Most often they are used in industrial facilities, in warehouses and in offices. However, the cylinder mechanism is suitable for an interior door in the apartment. Due to its special design, the lock is distinguished by an affordable price, quick installation and ease of operation.

The principle of the latch is that the mechanism "type cylinder" and special return plates are driven by door handles.


Another type of locking systems for entrance and interior door designs are magnetic mortise locks, working through special wrapping and two convenient handles. Holding the structure in the closed position is provided by a magnet. This mechanism does not have a lock, but it can be equipped with a metal or plastic tongue.

Ball (roller)

These are the most budget latch options. The mechanism is very simple, while you can not be afraid that the product will quickly fail. By purchasing such a locking system, you will not only save, but also get a stylish piece of hardware. On sale you can find roller locks of bright colors, due to the mobility of the mechanism of the product does not need an extra handle and work on the principle of "pull-push".

Please note that the roller lock model is suitable for light doors of general use, not intended for locking for a long time.

If you want to protect your home from the illegal entry of thieves and scammers, then responsibly approach the choice of the entrance door lock system.

When choosing a lock system in an apartment, there are many factors to consider. Pay special attention to the following criteria:

  • The material of manufacture. For wooden doors, any type of lock with a matte or glossy finish is suitable, for metal doors - steel with a more reliable mechanism, and PVC doors need plastic fittings.
