ABSTRACT:
An electronic locking system and method provides a control unit in a receiver to open a lock of a locking system when a transmission sequence output by a transmitter of the electronic locking system coincides with a reference sequence within a re-synchronization region in the receiver, the transmission sequence being formed by a user by repeated actuation of the transmitter and stored in a mark memory of the receiver. If necessary, the synchronization unit synchronizes the reference generator to the most recent transmission mark of the transmission sequence.
