Abstract
An electronic combination lock has the capability of generating the combination that is used to compare to the entered combination by combining data read from an electronic key and data unique to the lock and stored in the lock. The lock may be operated in a mode that requires two combinations and two separate keys to open the lock. This dual combination mode of operation is possible in several classes of operation such as Route, First Line Maintenance or Bank Mode. The lock also has a mode of operation wherein the lock may be shelved or returned to the factory mode by using a unique combination and a one-time use key for assistance whenever combinations are severely out of synchronization with the dispatching computer and without other correction options.
