There are many different kinds of door locks, they look different, can vary in size and appearance. The design of the door lock mechanism evolves slowly. The place of manufacture of the door lock does not matter, the door lock has a standard mechanism. The latchbolt and the latchbolt are always included in the door lock, the profile cylinder is a separate component. Only thanks to those elements of the mechanism the door lock may carry out its functions. To make the use of the lock more comfortable a pushing handle is installed on it that makes the door open and close, and a profile cylinder is needed for fixation of the door leaf in the closed position.

Why do door locks break?
There are many different reasons why door locks break, but one of the main reasons is the use of soft metals and alloys. Sometimes manufacturers use mild grades of steel, copper and aluminum alloys that may be used in the production of the internal device of the lock.
The main reasons for door locks failure
- Deformation of the door or doorway.
- Operating the lock in high humidity or high dust conditions, leading to oxidation or dusting of the mechanism.
- Failure of the lock mechanism and wear and tear of the mechanism elements.
Let’s learn how negative environmental conditions affect the lock’s performance.
Doors and doorways made of PVC, aluminum and wood are subject to deformation with time. Even a small change in the geometry of the door may cause displacement of the locking fittings relative to the striker. The design of the movement mechanism of the locking fitting is not designed to overcome the friction created by the interaction of the latch or deadbolt with the striker. This results in an additional load on the entire mechanism, which causes the mechanism to break.
The failure of the bolts and dowel pawls is much less common due to this reason. Using door locks in rooms with a high level of dust combined with a lack of maintenance and lubrication in a given period of time begins to experience increased internal resistance in those parts that are exposed to high loads A door lock can break down if its solution is ignored in the presence of this problem. This problem is particularly acute when used with a multi-point lock installed on the door. Rust usually affects door locks working under high humidity. Oxidation of the mechanism parts under constant strain may cause much inconvenience in the process of operation. Only preventive maintenance of the door latch may solve the problem of the oxidation of the mechanism. Preventive maintenance is very important but is not a panacea for breakages. Constant stresses that the lock is undergoing are also the cause of breakdowns. The door lock may be used for a long time if the prevention of failures and timely replacement of parts are done in time.
Time of lock replacement
Visual inspection does not always give complete information on the basis of which the lock can be replaced. The visual inspection may show that the lock looks good and almost like new, but it may be broken. The main characteristics that allow you to replace or repair the lock in time include:
- Purchase and replacement of the door. The lock for a new door must be chosen separately, often the purchased door does not have a lock.
- You have lost your keys. Of course, there are often duplicate keys, but intruders can use found keys. Changing the lock is the best way to avoid the negative consequences of this incident.
- Wear and tear on the lock mechanism. If you use a high-quality lock, it can also break. You can replace individual parts of the mechanism. It is best to compare how much a new lock will cost and the part of the lock that broke. It might be more profitable to replace the lock, since the breakage of one part can cause the other parts to break and you will end up replacing the lock, only with more effort. If high-reliability locks are required. A reliable lock is often not something you can pick on the first try. Repeated use of the lock reveals its flaws. If the lock does not suit the user, it is better to change it.
- It is necessary to change the lock in case of burglary. In this case, it is a matter of prime necessity.
- When buying a property, it is also necessary to change the locks. It is possible that the old owners may have left duplicates.
If there is at least one of the above reasons, then in order to avoid negative consequences replacement of the lock is mandatory in the near future.
