ABSTRACT:
An improved electronic lock includes a random bit-pattern generator which may be selectively cycled through a plurality of bit-pattern combinations to provide a code that can be stored in a mating electronic key. Several bit-patterns or codes may be stored in a single key for convenient use in operating a corresponding number of separate locks.
