ignition is off.
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.
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.
