There is no need jump terminals 4 and 8 that does not apply to this vehicle.

Here are the instructions again. You must follow them to the T for the procedure to work. If this does not work you may have to take it to the dealer so they can program the xmitters with the GM Scan tool.


Transmitter Programming

Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.
