Abstract

A special key with four blades, and X shaped in cross section, fits into a cylinder lock suitably shaped to receive it, and has slots in one or more of the blades to operate the lock, the other blades carrying ridges and slots representing binary data which is sensed by a reading device which passes the information to an electronic control system which employs a memory. If the sensed information corresponds to the information stored in the memory, the control system allows the lock to operated.
