GRAND PRIX KEY FOB PROGRAMMING INSTRUCTIONS

Transmitter Programming
No Tools Required
In the event that a transmitter is lost, program the old and the new transmitters into the memory of the remote control door lock receiver. Up to 4 transmitters may be programmed.


Important
Once the keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If you program multiple receivers simultaneously, the same transmitter could possibly be programmed to more than 1 remote control door lock receiver.


Perform the following steps:

Sit in the vehicle driver's seat. (actually it’s much ezr from the front pass seat)
Remove the ignition key from the ignition lock cylinder.
Close all of the vehicle's doors.
Remove the MALL PGM fuse from the fuse panel. Refer to Electronic Diagnosis in Body and Chassis.
Turn the ignition lock cylinder to the ACC position.
Turn the ignition lock cylinder OFF, then back to ACC within 1 second.
Open and then close any vehicle door. You will hear a chime when the remote control door lock receiver enters the programming/diagnostic mode. If you do not hear a chime, start again at step 1.

Important
After 7 seconds, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you will hear a chime confirming successful programming.


Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
Repeat step 8 in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse back into the fuse panel. Refer to Electrical Diagnosis in Body and Chassis.
Validate that all the transmitters that were programmed operate properly. Refer to Keyless Entry System Operation .

Answer 2

Give this a try, It's what you pay the dealer big bucks to do even if it sounds silly.
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the DOOR unlock switch.
While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the DOOR unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one keyless remote. After a delay of approximately 15 seconds , the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation. You may have to pull a fuse, but I forgot the letters on it, thats what I had to do with my 2004 Pontiac Grand Prix GTP, I do remember the fuse was all capital letters with nothing that may sense to me.

If you have a factory radio with RDS you should be able to do it with the stereo. Follow these steps to access the Key Fob programming:

1. Turn off the radio
2. Press the DISP button and wait for a beep
3. You will be in the settings menu, here you can find where to program the remotes. I believe you just turn the tuning knob to change menus and press DISP to enter the menu. The radio will walk you through the process of reprogramming the remotes.

You should be able to find the exact steps in your owner's manual. If you don't have one, go to www.mygmlink.com and sign up, and you'll be able to download your manual in PDF format.
