This is not only the most popular type of locks, but also the simplest and most convenient in terms of self-repair. Due to the design feature - the presence of a removable cylinder - a complete replacement of the entrance door cylinder mechanism itself is not required. If you just need to change the cylinder, and the mechanism itself is working normally, then replacing the entrance door lock core will be the best solution. It is also not necessary that the cylinder and the lock were produced by the same manufacturer, the main thing is their clear coincidence in size.
The lever lock is distinguished by a more complex secret mechanism, which consists of a package of plates with figured cutouts (levers).
The key to such a lock is in the form of a long round rod with one or two plates at the end. Repair and replacement of the lock of the front door of the apartment in this case is quite specific, and an amateur is unlikely to cope here. In such a situation, it is better to turn to professionals.
Much less often, other types of locks are used for entrance metal doors:
Even in simple locks, replacing the front door cylinder can lead to undesirable consequences. For example, the lock can simply jam. If you have doubts about your own abilities, it is better to invite an experienced master.
If you are performing a self-replacement in order to save money, buy a new lock or spare parts from authorized retail outlets so that the mistakenly purchased item can be returned or exchanged. Otherwise, replacing the larva in the front door lock at a cost may cost more than the services of a master.
