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, 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 only four transmitters matched to it. Battery Replacement Under normal use, the battery in yourkey chain transmitter should last about two years. You can tell the battery is 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 battery. For battery replacement, use one Duracell@battery, type DL-2032, or a similar type. To replace the battery: 1. Insert a coin into the notch near the keyring. Turn the coin counterclockwise to separate the two halves of the transmitter. 2-13
