Cylinder locks are a widely used and versatile type of door lock known for their security and ease of use. The term "cylinder lock" refers to the specific mechanism within the lock that uses a cylindrical core to control the locking and unlocking functions.
The core of a cylinder lock contains a series of pins of varying lengths that align along the shear line when the correct key is inserted. When the key is turned, it lifts the pins to the correct height, allowing the lock to rotate and the door to open. The design of cylinder locks provides a reliable and effective means of securing doors in residential, commercial, and industrial settings.
