Abstract

PURPOSE: To improve safety by a method wherein when a key is inserted in the key hole of a locker mechanism, a locker circuit is connected to a key circuit, and in order to perform key collation by means of a CPU, a pair of connectors engageable with each other are provided.
CONSTITUTION: A registered key having a key circuit 2 formed with an EEPROM 11 to store an ID number of itself and a key word in a manner that the ID number and the key word can be rewritten is inserted in the key hole of a locker mechanism having a locker circuit 1 formed with a CPU 4 to control reading and writing and the motion of an ID unlatch means. By means of a pair of connectors 9 and 10 engageable with each other, an I/O circuit part 6 of a locker circuit 1 is connected to the EEPROM 11 of a key circuit 2 to execute key collation and other operation by means of the CPU 4. This constitution enables facilitation of variation of a key word, and permits improvement of safety.
