You can match a transmitter to as many different vehicles as you own, provided they are equipped with exactly the same model svstem. (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. For battery replacement, use two Duracell@ batteries, type DL-20 16, or a similar type. Battery Replacement Under normal use, the batteries in your key chain transmitter should last about twoyears. 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 toyour vehicle before the transmitter works, it's probably time to changethe batteries. To replace the batteries: 1. If your transmitter has a screw, remove the screw from the back cover. If there is no screw, carefully pry off the cover by inserting a dime (or similar object) in the slot between the covers and twist. 76
