Keys, Doors, and Windows See your dealer who can service the theft-deterrent system and have a new key made. It is possible for the theft-deterrent system decoder to learn the transponder value of a new or replacement key. Up to eight keys can be programmed for the vehicle. The following procedure is for programming additional keys only. To program a new key: 1. Verify that the new key has stamped on it. 5. The security light will turn off once the key has been programmed. It may not be apparent that the security light went on due to how quickly the key is programmed. 6. Repeat Steps 1-4 if additional keys are to be programmed. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. 2-25 The security light in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system. One or more RKE transmitters can be matched to the vehicle's immobilizer control unit. Only a correctly matched RKE transmitter will start the vehicle. If the RKE transmitter is ever damaged, you may not be able to start your vehicle. When trying to start the vehicle, the security light comes on briefly when the ignition is turned on. If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition control knob off and try again. 1 2. Insert the current key in the ignition and start the engine. If the engine will not start, see your dealer for service. 3. After the engine has started, turn the key to LOCK/OFF, and remove the key. 4. Insert the key to be programmed and turn it to ON/RUN within 10 seconds of the ignition being turned to LOCK/OFF in Step 3. Immobilizer Operation (Keyless Access) This vehicle has a passive theft-deterrent system. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the ignition control knob is turned to LOCK/OFF. The immobilization system is disarmed when the ignition control knob is turned and a valid transmitter is found in the vehicle.
