Locks and Security Automatic arming The vehicle is armed immediately after switching the ignition to the 1 (LOCK) position. The theft indicator will flash every two seconds to act as a theft deterrent when the vehicle is armed. Automatic disarming The vehicle is disarmed immediately after the ignition is turned to the 3 (RUN) position. The theft indicator will illuminate for three seconds and then go out. If the theft indicator stays on for an extended period of time or flashes rapidly, have the system serviced by your authorized dealer. Replacement Integrated Keyless Transmitters (IKT) and coded keys Note: Your vehicle comes equipped with two Integrated Keyhead Transmitters (IKTs). The IKT functions as both a programmed ignition key that operates all the locks and starts the vehicle, as well as a remote keyless entry transmitter. A maximum of eight coded keys can be programmed to your vehicle; only four of these eight keys can be IKTs with remote entry functionality. If your IKTs or standard SecuriLock™ coded keys are lost or stolen and you don't have an extra coded key, you will need to have your vehicle towed to an authorized dealer. The key codes need to be erased from your vehicle and new coded keys will need to be programmed. Replacing coded keys can be very costly. Store an extra programmed key away from the vehicle in a safe place to help prevent any inconveniences. Please visit an authorized dealer to purchase additional spare or replacement keys. Programming spare keys You can program your own Integrated Keyhead Transmitters or standard SecuriLock™ coded keys to your vehicle. This procedure will program both the engine immobilizer keycode and the remote entry transmitter portion of the IKT to your vehicle. Note: A maximum of eight coded keys can be programmed to your vehicle; only four of these eight can be IKTs with remote entry functionality. 138 2008 Sable (mgo) Owners Guide (post-2002-fmt) USA (fus)
