Adding Keys Procedure
You may add up to 10 additional master keys or valet keys using this procedure when a learned master key is available. This procedure adds keys only and does not erase previously learned keys. Keys to be learned must duplicate mechanical cut of current key. If more than one valet key is to be learned, immediately precede each valet key with a learned master key.
With a previously learned master key, turn ignition switch to RUN position. with engine off. Turn ignition switch to OFF position and remove key. Within 10 seconds insert key to be learned. Turn ignition switch to RUN position. with engine off. Vehicle has now learned new key.
