ELECTRONIC COMBINATION LOCK SECURITY SYSTEM

摘要

An electronic security system includes an electronic lock mechanism (9005) and an electronic key (100), each of which is provided with a microprocessor controller and a memory storing data including an ID code and encryption key codes. The lock microprocessor (601) may either change ID codes stored in its memory or encrypt a seed number to be used for determining access to the lock. A novel combination dial electronic lock (9001) utilizes the electronic lock dial to prevent rotation of the combination dial (9015) unless an authorized electronic key has been inserted into the electronic lock.
