Abstract
A method for clearing unlocking key codes in an electronic locking device in which the unlocking circuit is arranged to be actuated when the code of a magnetic card read by the card reader (1) agrees with an unlocking key code set in the memory (4), the method comprising using a first clearing card which will function only when the door associated with the locking device is open and a second clearing card which will function only when the door is closed, setting the codes of the first and second clearing cards in specified separate addresses in the memory in the code setting mode for setting the codes of the clearing cards in the processing unit (CPU) of the electronic locking device, determining whether the door is open or closed in the normal operation mode of the CPU, and clearing the unlocking key codes only when the code read by the card reader (1) is identical to the code of the first clearing card set in the above-mentioned manner and the door is open, or when the code read by the card reader (1) is identical to the code of the second clearing card set in the above-mentioned manner and the door is closed.
