Key: Testing and Inspection






Vehicle Key Function, Checking

- Separate keys so that the function of each key can be checked individually.

- Mechanically lock and unlock vehicle with keys on driver's door.

- Insert keys in ignition and start engine one after the other.

- If engine switches off by itself after about 3 seconds and "save" appears in the odometer display, the key has not been programmed to the immobilizer.

- Repair measures: Guided Fault Finding (Programming vehicle keys).

- Note in the delivery check list the number of keys checked and given to the owner.
