Locks and Security Tips: • Only use Integrated Keyhead Transmitters (IKTs) or standard SecuriLock™ keys. • You must have two previously programmed coded keys (keys that already operate your vehicle's engine) and the new unprogrammed key(s) readily accessible. • If two previously programmed coded keys are not available, you must take your vehicle to your authorized dealer to have the spare key(s) programmed. Please read and understand the entire procedure before you begin. 1. Insert the first previously programmed coded key into the ignition. 2. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least three seconds, but no more than 10 seconds. 3. Turn the ignition to the 1 (LOCK) position and remove the first coded key from the ignition. 4. Within ten seconds of turning the ignition to the 1 (LOCK) position, insert the second previously coded key into the ignition. 5. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least three seconds, but no more than 10 seconds. 6. Turn the ignition to the 1 (LOCK) position and remove the second previously programmed coded key from the ignition. 7. Within twenty seconds of turning the ignition to the 1 (LOCK) position and removing the previously programmed coded key, insert the new unprogrammed key (new key/valet key) into the ignition. 8. Turn the ignition from the 1 (LOCK) position to the 3 (RUN) position. Keep the ignition in the 3 (RUN) position for at least six seconds. 9. Remove the newly programmed coded key from the ignition. If the key has been successfully programmed it will start the vehicle's engine and will operate the remote entry system (if the new key is an Integrated Keyhead Transmitter). The theft indicator light will illuminate for three seconds and then go out to indicate successful programming. 139 2008 Sable (mgo) Owners Guide (post-2002-fmt) USA (fus)
