A keypad lock is a type of locking mechanism that uses a numeric keypad instead of a traditional key. Users enter a specific code to unlock the door, making it convenient and secure. Keypad locks are commonly used in residential and commercial settings, providing easy access without the need for physical keys. These locks can be battery-operated or hardwired and often feature additional security options, such as automatic locking or temporary codes for guests. Keypad locks are popular for their ease of use and ability to eliminate the risk of losing keys, enhancing overall security for properties.
