2-12 Keys, Doors and Windows • Do not attempt to start the vehicle with a non-approved key. Immobilizer Operation Your vehicle has a passive theft-deterrent system. The system is automatically armed when the key is removed from the ignition. The system is disarmed when the key is turned to ON/RUN. You do not have to manually arm or disarm the system. The key uses a transponder that matches an immobilizer control unit in your vehicle and automatically disarms the system. Only the correct key will start the vehicle. If the key is ever damaged, you may not be able to start your vehicle. If the vehicle does not start: • Do not disassemble the key. When trying to start the vehicle, if the engine does not start, the key may have a damaged transponder. Turn the ignition off and try again. If the engine still does not start, and the key appears to be undamaged, try another ignition key. If the engine still does not start, your vehicle needs service. See your dealer/retailer to service the theft-deterrent system and have a new key made. The following procedure is for programming additional keys only. If all vehicle keys are lost or no longer work, see your dealer/retailer. A new key must be made prior to programming. A maximum of four keys can be programmed for your vehicle. The key is purchased as two sections: the key blade and immobilizer section (A) and the remote keyless entry and remote start system section (B). Do not join the two key sections until programming is complete. To program a new section (A): 1. Insert the original, already programmed key into the ignition and start the engine. If the engine does not start, see your dealer/retailer. 2. Remove the key from the ignition. • Make sure the fold away key is fully extended. • Avoid attaching several keys with the ignition key. • Avoid attaching keys from other vehicles to the ignition key.
