Matching Transmitter(s)To Your Vehicle Each remote keylessentry transmitter is coded to prevent another transmitter from unlocking yourvehicle. If a transmitter is lostor stolen,a replacement canbe purchased through your dealer. Remember to bring any remaining transmitters with you when you go your to dealer. When thedealer 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 two transmitters matched to it. You can match your transmitter to as many 1997 General Motors vehiclesas you own, as longas they have the same remote Keyless Entry System. Contact your dealer for assistance with this. Battery Replacement Under normal use, battery in your the remote keyless entry 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 vehiclebefore the transmitter works, it's probably time to change the battery. I NOTICE: When replacing the battery, use care to touch not any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter.
