This is a challenging issue and is difficult to address. This video will explain the principles behind door locks and the different types that are available. A door lock is composed of multiple parts. Although locks may have various forms, certain elements will have a commonality to each lock. They may consist of a bolt, strike plate or spindle as well as knob and spring.
So, how does a door lock work? If a door is locked, the latch gets inside the striking place and out of the lock’s cylinder. This ensures that the door is closed even when the key is in place. The typical key has ridge patterns that align with pins to turn the piston. Only the correct key pattern will cause the door unlock. There are different types of locks for doors. A few of them are: the locking trident for security doors, the lockset for classrooms, the security lockset for privacy, the passage lockset and the storeroom lockset. They all use the same mechanism for unlocking and locking the doors, but some are unique.
