Faulty Transponder or Lost Key






Faulty Transponder or Lost Key

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

If the transponder is faulty, the entire vehicle key must be replaced.

- Order a replacement key through distributor or importer with vehicle-specific lock number using VIN.

- Perform the adaptation on all vehicle keys using Vehicle Diagnosis, Testing & info. System (VAS 5051B) (or other VAS 505X class tester) in operating mode "Guided Fault Finding".
