gm keyless entry PLEASE HELP

[AKA-FERRARI]

@FightinMike

1. Sit in the driver’s seat
2. Remove the ignition key from the ignition lock cylinder
3. Close all the doors
4. Press and hold unlock on the door lock switch (on the door)
5. While holding the door lock switch in the unlock position, insert and remove the ignition key twice. DO NOT ROTATE THE KEY… JUST SLIDE IT IN AND BACK OUT.
6. Insert the ignition key the third time, leaving the key in the ignition cylinder. DO NOT TURN KEY
7. Release the door lock switch. You will hear 3 chimes indicating the transmitter
   programming is active.
8. Press and hold the lock and unlock buttons on the keyless entry remote at the same time (one remote) for 12 seconds. You will hear two chimes. This indicates the
   transmitter has been programmed.
9. Repeat step 8 for all additional transmitters to be programmed
10. Exit programming by removing the key from the ignition cylinder
