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 transmitters to another vehicle. You can tell the battery is weak if the KEY FOB BATTERY LOW message appears in the message center. If you get this message, the battery in the key fob needs to be replaced. 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. 1. Insert a flat object, such as a coin, into the slot on the side of the transmitter and twist to separate the halves. 2. Gently pry the battery out of the transmitter. Do not use the metal flanges to remove the battery. 3. Replace the battery. 4. Reassemble the transmitter. Make sure the halves are snapped together tightly so water will not get in. 5. Press and hold the LOCK and UNLOCK buttons for seven seconds to synchronize the transmitter. 6. Check the transmitter operation. Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about three years. United States Canada 2-7
