Abstract
An electronic lock in which new passcodes can be added and/or deleted without specifying the user slot to which the new passcode should be assigned. A circuit in the electronic lock determines whether the new passcode to be added is unique compared to existing passcodes stored in memory. If so, the circuit searches for an available user slot for which no authorized passcodes are associated and associates the new passcode with an available user slot.
