Matching Transmitter(s) to Your Vehicle Each RKE 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/retailer. Remember to bring any remaining transmitters with you when you go to your dealer/retailer. When the dealer/retailer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer/retailer 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. To replace the battery: Battery Replacement Under normal use, the battery in the RKE transmitter should last about two years. 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. 1. Insert a coin, or similar object, in the slot between the covers of the transmitter housing. Gently pry the transmitter apart. 2. Remove and replace the battery with a three-volt CR2032 or equivalent battery. 3. Align the covers and snap them together. 4. Check the operation of the transmitter. 2-6
