Locks and Security 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 the theft indicator light will illuminate for three seconds and then go out. If the key was not successfully programmed, it will not start your vehicle's engine and the theft indicator light will flash on and off, or stay on for more than three seconds. If failure repeats, bring your vehicle to your dealer to have the new key(s) programmed. To program additional new unprogrammed key(s), repeat this procedure from step 1 for each additional key.

If there is any potential perimeter anti-theft problem with your vehicle, ensure ALL remote entry transmitters are taken to the dealership to aid in troubleshooting.

When you press the lock control twice within three seconds on your remote entry transmitter, the horn will chirp once to let you know that all doors/hood/liftgate and liftgate window are closed. Note: If any of these are not closed, the horn will chirp twice to warn you that a door/hood/liftgate or liftgate window is still open. • Press 7 • 8 and the 9 • 0 controls on the keyless entry pad at the same time to lock the doors (driver's door must be closed). There is a 20 second countdown when any of the above actions occur before the vehicle becomes ARMED. Each door/hood/liftgate or liftgate window is armed individually, and if any are open, they must be closed for the system to enter the 20 second countdown. 94
