Key locks are fundamental security features in the realm of door hardware, providing a reliable and traditional means of securing doors. These locks typically operate through the use of a physical key, which is inserted into the lock cylinder to engage or disengage the mechanism.
Key locks come in various types to suit different door applications. Deadbolt locks, for instance, offer enhanced security due to their single, robust bolt that extends deeply into the door frame when locked. Cylinder locks, commonly found in both residential and commercial settings, use a cylindrical mechanism that turns when the correct key is inserted.
