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.
To match a transmitter, use the following instructions.
1. Have both transmitters that will be matched to the
car present, even if only one is new. Remove the car
keys from the ignition and have them with you.
2. Find the 16 pin diagnostic connector above the
accelerator pedal.

3. Use a jumper wire with alligator clips at both ends to
ground (Terminal 4) to program (Terminal 8).
Grounding the program terminal erases the system
memory and causes the doors to lock and unlock
once. This means the system is ready to be matched
to the transmitter.
4. Keeping the program terminal grounded, press the
UNLOCK button on the first transmitter. The door
locks will lock and unlock again to indicate the
transmitter is now matched. If there is no response,
check the transmitter batteries. If you do not want to
match a second transmitter, proceed to Step 6.
5. Still keeping the program terminal grounded, repeat
Step 4 with the second transmitter. If you disconnect
the ground wire before completing this step, only the
first transmitter is matched. If you make a mistake,
disconnect the jumper wire and start over at Step 3.
6. Remove the jumper wire. (Note: The system will not
operate if the jumper wire is still connected.)
7. Test the operation of both transmitters with the
