A keypad lock is a type of locking mechanism that requires a numerical code to unlock. Instead of using a traditional key, users enter a specific sequence of numbers on a keypad. This system is often used for securing doors, safes, and electronic devices, providing a convenient and keyless way to enhance security. Keypad locks can be found in various settings, including homes, offices, and vehicles. They come in different styles, such as standalone units or integrated systems with smart home technology. Many models also offer features like temporary codes for guests and alarms for unauthorized access attempts.
