A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token, coin, etc.), by supplying secret information (such as a number or letter permutation or password), or by a combination thereof or only being able to be opened from one side such as a door chain.

The lock installed on the door leaf and door frame of the building that needs to be opened and closed is generally composed of a lock body (including a lock tongue, a control mechanism and a brake mechanism) and a lock panel, a handle and a cover plate.

According to the structural characteristics, locks can be divided into rim lock, mortice door lock and door lock with knobs.

Today’s door locks feature advances in technology and functionality. While entry locks provide improved security, locking privacy door knobs for your bedroom and bathroom look beautiful and enhance your decor.

Selecting new locks, whether for your home or business, can easily be overwhelming. While the vast variety of options to choose from is certainly nice, it also makes narrowing down your selection to the best lock extremely difficult. Simply put, there are dozens of different types of locks, each with their own specific set of pros and cons. In addition, each lock has its own best application.
