A keypad door lock is a security device that restricts access to a building or room through a door using a numeric keypad. It optimizes work environments by providing controlled entry, eliminating the need for physical keys and simplifying access management. Authorized users can enter a unique code to unlock the door, enhancing security and convenience while minimizing the risk of lost or stolen keys. This system also allows for easy reprogramming of access codes, improving flexibility and efficiency in maintaining secure access to workspaces.
