摘要： The anti-theft system is placed in the initialization state by activating a key in the ignition lock in a predescribed manner that is unusual relative to the day to day operation. A bidirectional dialog then takes place with the key via an immobilizer system. If the dialog is recognized as authorized, a start value is transmitted, on the one hand from the immobilizer to the key and on the other hand from the key to the receiver of the lock system. The start value is used in the key to generate a rolling code, and is used in the receiver to generate a reference code to be compared with it.
