ID CODES REGISTRATION PROCEDURE



caution
  • When the door service key set or the glove box service key set is replaced as a unit, do not register the barcode No. attached to the key. If registered, starting the engine by using the conventional key becomes impossible. The new key will not be able to start the engine, too, because it has a different key groove.
  • Do not register the keyless operation key registered for other vehicles.
