Electronic locking system i.e. door locking system, for access and/or driving authorization of motor vehicle i.e. car, has electronic key actuated while including valid signals for authentication of another key
The system has a transmitter operated with a transmission channel that includes a predetermined transmitter frequency. Signals are transmitted between electronic keys (4, 5) for providing a coded operating signal for an authentication of one of the keys, so that a change in the state of the other key is caused after a positive analysis of the transmitted operating signal to the authorized former key. A transmitted signal (7) is evaluated in a receiver for validation, and the latter key is actuated while including the valid signals for the authentication of the former key.
