This worked for me on my 2002 Chevy Venture. I got it from a post from a 1999 GMC post.

Important! Once the BCM enters program mode, all transmitters must be programmed at the same time. Any transmitters not learned at this time will be erased.

1) Remove the key from the ignition cylinder

2) Remove the BCM PRGRM fuse from the fuse panel

3) Close all the doors

4) Close the liftgate

5) Turn the ign lock cylinder to the ACC. position

6) Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second

7) Open and close any door
Achim will be heard when the system enters the BCM programming mode

IMPORTANT!
After 7 seconds a chime may be heard confirming successful synchronization. It is necessar to wait approximately 14 seconds for a second chime that will confirm successful programming.

8) Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds

9) Repeat the previous step on each additional transmitter to be programmed.

10) Remove the ignition key from the ignition cylinder

11) Install the BCM PRGRM fuse back into the fuse panel.

Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 1998 S/T pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.


With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel. The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
Locking the doors
Unlocking the doors

Important
All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.


Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
Locking the doors.
Unlocking the doors.
Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool instructions.

Did any of the methods after your post work? If so, which one, and can I get the code on the back of your key fob? I will be doing my Jimmy soon too.

Thanks

Thanks Flatrater !!!!

Got my Jimmy w/only 1 remote, bought one off ebay for 5.00, called the dealer, and he wanted $ 35.00 to reprogram the new remote, I was willing to toss it till I saw your post, tried it and it worked ! Where on earth did you get this info ? Really Appreciate it ... Thanks a Million !

Flatrater, thanks a million! I just bought a Jimmy that came with an old broken keyfob. I bought a new one from the dealer knowing I could find something on the web to program it. Thanks to your post I will NOT be going to the dealer or anybody else and paying to program the keyfob. One side note to people using this post to program their keyfob, it takes about 15-20 seconds before the keyfob locks and unlocks the doors. Once it does, you are finished unless you have more than one keyfob. Thanks again, Flatrater.
