Adding Keys (Export - Including Canada)

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

To initiate, this procedure requires that 2 learned master keys be available.
A total of 10 master keys or valet keys may be programmed to a single vehicle.
If more than one valet key is to be learned, immediately precede each valet key by 2 learned master keys.
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.

With a previously learned master key, turn ON the ignition with the engine OFF.
Turn OFF the ignition and remove the key.
Within 10 seconds insert a second previously learned master key. Turn ON the ignition with the engine OFF.
Turn OFF the ignition and remove the key.
Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key.
