An electric rim lock is a locking device installed on the surface of a door. It combines electronic components with mechanical structures, typically operated via electricity. It may include features like keypad entry, remote control, or smartphone integration. The lock has a latch or bolt that extends or retracts to secure or release the door. It is commonly used in residential, commercial, and industrial settings for enhanced security and convenience. Electric rim locks offer keyless entry and can be integrated with other security systems, though they require a reliable power source and may be more expensive than traditional mechanical locks.
