A door lock is a device designed to secure a door, preventing unauthorized access and enhancing safety. It typically consists of a mechanism that operates with a key, code, or biometric input. The lock engages a bolt or latch that fits into a strike plate on the door frame. Door locks come in various types, including deadbolts, which offer higher security, and knob locks, which are more common for residential use. Electronic and smart locks provide advanced features such as keypads and smartphone connectivity, while mortise locks are often used in commercial settings. Each type of lock offers different levels of security, convenience, and functionality.
