Matching Transmitter(s)To Your Vehicle Each key chain transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, areplacement 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 toyour vehicle, any remaining transmitters must also be matched. Once the new transmitter is coded, the lost transmitter will not unlock your vehicle. Each vehicle can have only two transmitters matched to it. Io replace the batteries: Battery Replacement Under normal use, the batteries in your key chain transmitter should last about two years. You can tell the batteries are weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the batteries. Use two Duracell@ type DL20 16, or a similartype. 1. Insert a dime in the side seam of the transmitter housing, near the key ring hole. 2. Twist the dime to separate the two halves of the transmitter housing. Separate the housing, bottom half first. 3. Remove and replace the batteries. Put the new batteries in with the printed side down. 4. Align the housing and snap the halves together. 2-5
