  • To initiate, this procedures requires that a learned master key be available.
  • A total of 10 keys may be programmed to a single vehicle.
  • This procedure adds keys only. The procedure does not erase previously learned keys.
  • The keys to be learned must duplicate the mechanical cut of the current key.
  • If more than one valet key is to be learned, immediately precede each valet key with a learned master key.
  1. With a previously learned master key, turn ON the ignition, with the engine OFF.
  2. Turn OFF the ignition and remove the key.
  3. Within 10 seconds of turning OFF the ignition, insert the key to be learned and turn ON the ignition. The vehicle has now learned the new key.
