Should interference to this system occur, try this: Check to determine if battery replacement is necessary. See the instructions on battery replacement. 0 Check the distance. You may be too far from your vehicle. This product has a maximum range. Check the location. Other vehicles or objects may be blocking the signal. See your GM dealer or a qualified technician for service. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. Operation When you press UNLOCK, the driver's door will unlock automatically. If you press UNLOCK again within five seconds, all doors will unlock. All doors will lock when LOCK is pressed. 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, the remaining transmitters must also be matched. Once the new transmitter is coded, the lost transmitter will not unlock your vehicle. You can match a transmitter to as many different vehicles as you own, provided they are equipped with exactly the same model system. (General Motors offers several different models of these systems on their vehicles.) Each vehicle can have only two transmitters matched to it. See your dealer to match transmitters to another vehicle. 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. 2-7
