Faulty Transponder Or Lost Key

The transponder is integrated in the ignition key and cannot be replaced separately.

If the transponder is faulty, the entire ignition key or the transmitter must be replaced.

Depending on the immobilizer generation, perform the following function in the "Offboard Diagnostic Information System Service" :
