Theft-Deterrent System The remote keyless entry transmitter will arm the theft-deterrent system whenever the doors are closed and you push the lock button when the ignition is off. It will disarm the system when you push the unlock button. You can tell the battery is weak if the transmitter will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it is probably time to change the battery. Notice: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. Matching Transmitter(s) to Your Vehicle Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it. See your dealer to match additional transmitters to your vehicle. Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about four years. To replace the battery, do the following: 1. Insert a thin coin, or similar object, into the notch near the key ring. Turn it counterclockwise to separate the two halves of the transmitter. 2-8
