KEY, CHECK FUNCTIONALITY
Separate keys so that the function of each key can be checked individually.
Insert each key into the ignition and start the engine.
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 measure: Guided Fault Finding (Programming vehicle keys).
Note in the delivery check list the number of keys checked and given to the owner.
