ABSTRACT:
An intelligent lock that can set a key code by itself, a key which can be used for many locks, as well as a setting tool are presented. The key may include a housing, a battery, a head, a group of contacts provided on the head, a non-volatile memory, and a special key code. The contacts for power supply and data transmission are connectable with two ends of the battery through respective wires. The intelligent lock system can easily set or cancel a key code by itself, and a single key can operatively replace many kinds of keys. The intelligent lock is cheap and easy to use.
