A door is opened and closed countless times every day. The door lock is an essential device for this function. The individual components of a lock all have their own important function.

1. One of the components is the lock latch

The lock latch is an essential part of the door lock. The lock latch is often also called a door latch. It is used to ensure that the door automatically clicks into place when it is closed.

2. The door handle belongs to the door lock

One of the important components is of course the doorknob. The door is opened using the latch. Pressing the door handle ensures that the lock latch springs back so that the door can be opened.

3. The strike plate is located in the door frame

The strike plate usually has two recesses, the upper one for the lock latch and the lower one for a bolt. The strike plate is visible on the outside of the door lock as an elongated sheet. When the door lock is opened, the lock latch is released from the strike plate.

4. The door bolt provides a double hold

The door is also locked by the door bolt, which is attached to the inside or outside of the door lock. These door bolts are operated either by hand or with a key.

5. The key is inserted in the lock cylinder

One of the last important components is the lock cylinder. This is placed in the lock and a key or chip card triggers a mechanism that either unlocks or locks the door. The lock cylinder is used to lock the door.
