It depends entirely on the model of car..
OK, here it is:
You have to program all the transmitters you want to use as part of this process, as it will erase all memory of existing transmitters.
-Remove ignition key
-Take out BCM PRGRM fuse from the fuse panel
-Close all doors and liftgate
-Turn ignition key to Accessory
-Turn key to Off, and back to Accessory within 1 second
-Open and close any door - chime will sound
-For each transmitter in turn, press and hold both LOCK and UNLOCK for 14 seconds (chime may be heard at 7 seconds, keep holding)
-Remove key
-Reinstall BCM PRGRM fuse
Looks like your headed to the dealer.
