Such mechanisms have the greatest load, so they are subject to a variety of breakdowns. Replacing the door lock of this type requires a certain knowledge and skills. It is important to not only know the type of lock, but also to understand its design features.

In some cases it is necessary to carry out the replacement of the lock in the door

Among all the possible damages are several that occur most frequently. A particular problem may arise at any stage of operation of the locking mechanism. Knowledge of the causes of failure allows for rapid replacement of devices. Let us see what are the most common faults.

Helpful information!The most common problem that leads to the need to change the lock, is the loss of keys. In this case, the installation of the new device is an obligatory precaution. Of course, you can remove the duplicates with the spare key, but for the safety of the home, it is advisable to carry out the complete replacement of the lock.

Box locking device may need when purchasing a new door. Most of the input paintings realized without the locking mechanism so the lock is adjusted individually for each specific case. Currently, there is an opportunity to purchase a door fitted with a locking device, but in order to save funds perform better independent sidebar of the door lock.

Another common problem requiring replacement mechanism is considered failure of the central part of the lock, which is called a larva (or sekretki). The reason for failure of this element is usually frequent operation of the lock, leading to wear of its parts.

Change door lock may be required in the case where the device does not meet the required safety class. If the mechanism does not meet the owners, then it is most often replaced by more reliable.

Among other things, the new tie-locking device may be needed after the penetration of hackers into the apartment. In this situation, experts recommend to carry out the complete replacement of the front door with all safety elements. And this event made when I pass a home to new owners.

The most frequent breakdowns, requiring replacement lock the front door, and their causes

The situations that lead to the need to replace the locking mechanism can be very different. This event is not always done in the case of failure of the device. The locking mechanism is usually subjected to heavy loads, which affect its components. This leads to their deterioration. Consider whether the fault is most often encountered in the operation of the door locks.

A common problem is the disruption of the tongue, is responsible for holding the door in the closed position. In this case, you can completely change the lock, but the correct solution is the elimination of breakage. This problem is most often caused by two reasons:

• tilting of the door leaf;
• mismatched tongue with an aperture for mounting plates.

Misalignment of the frame can be fixed by yourself. To do this, you must make an adjustment loop which can move away due to weak attachment. The position of the return strap can also be corrected.

Many users lock mechanisms are faced with the same problem - a key jam in the device. This trouble is most often associated with blockage of the internal mechanism. Replace the lock on the door is sometimes easier than to disassemble and clean it. In this situation, you must correctly assess their knowledge and capabilities.

Least likely locking device fails due to mechanical action. This problem can be diagnosed very easily, since it is accompanied by a breakdown of the mechanism housing.

Replacing door lock: Device types and their characteristics

All locking mechanisms that are used on the front door, are classified on several grounds. First of all locks are differentiated into groups depending on the installation options. In today's market you can find these types of devices:

• Mortice;
• attachments;
• overhead.

Mortice mechanisms are most popular. They are often sekretki and have high protective performance. Such a lock is difficult to crack (when compared with patch models). Coupling devices are used on the front door is extremely rare.

Before you begin to change the locks to the iron door, you must determine the type of device. Thus, knowledge of the species of the locking mechanism is very useful. Another indicator by which locks are divided into types, is their design. Depending on the characteristics of the device are the following model locking devices:

• cylinder;
• lever;
• disc;
• cruciform.

Replace the door lock cylinder type can be either fully or partially. This is due to the design features of such devices. These include a core (larva) which comprises a mechanism by opening key. That he often fails. The reasons for this may be several. Problems are caused in the core is plugged, and also all possible breakages, occur as a result of wear of its individual elements.

Lever locking mechanisms differ from the cylinder in its design. As for the type of installation, they are mounted only one method - the tie. It is important to remember that the beginner will be hard to understand the intricacies of the installation of this device. To change the lock on the metal door is necessary to study the appropriate instructions carefully, and encouraged to read the videos on this subject.

Helpful information!Some manufacturers produce lever locking mechanisms that support the function of conversion. This is a significant advantage, through which removes the need to replace the lock (e.g., loss of keys).

Disc Brake divided into two groups: automatic and semi-automatic. Such locks include in its membership sekretki. Thus, at breakage can not change the locking device completely, but to limit the replacement core. In order to know how to change the lock cylinder the door, you must read the instructions corresponding to this type of locking mechanism.

Finally, the cross-shaped device also includes a cylinder mechanism. They are quite easy to identify the keys, which have projections on all four sides. Such locks are not very popular and rare.

How to change the door lock: determining the type of locking mechanism

To replace the latch mechanism in the front door, you must first determine its type. It will pick up a similar device and explore all the nuances of the installation.
