Immobilizers

Battery-free passive RFID anti-theft immobilizers have become standard for automotive security systems. For immobilization, the vehicle sends a challenge to the transponder and verifies its response by operating with different crypto-algorithms. If communication protocol between the reader (generally an air coil located around the key slot) and the key transponder is correct, car’s ignition is released. Generally, electronic immobilizer and door locking system are integrated into the same transponder in the ignition key. These transponders are required to perform the same features than RKES application transponders.
