An electronic keypad lock is an electronic product that controls circuits or chips (access control systems) through password input, thereby controlling the closure of mechanical switches to complete and lock tasks. There are many types, ranging from simple circuit products to chip-based high-value-for-money products. The most widely used electronic keypad locks today are those with chips at their core, implemented through programming. Electronic locks are used in the field of security technology prevention, featuring anti-theft and alarm functions.
