Keyless Entry programing for the 96-99 guys...
 

I noticed there is no article for these guys. Saw this on CGP and imagine the bonnevilles are similar but not the same....It would be cool if someone could test it out.

GP version:
Remove the ignition key from the ignition lock cylinder.
Close all of the doors.
Remove the MALL PGM fuse from the fuse block.
Insert the ignition key into the ignition lock cylinder.
Turn the ignition to ACC. The body control module (BCM) will perform the following in order to identify the type of BCM installed in the vehicle:
- Flash the seat belt indicator 1, 2, or 3 times.

- Chime 1, 2, or 3 times.

Turn the ignition to OFF, and then back to ACC within 1 second. The BCM may begin to chime and flash diagnostic trouble codes (DTCs). If the BCM has stored any DTCs, refer to Diagnostic System Check - Body Control System in Body Control System.
Open and then close any vehicle door. The BCM will chime in order to confirm that the programming mode has been entered.
Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for approximately 14 seconds.
Important: After approximately 7 seconds the BCM will chime once to confirm that synchronization has been completed. After approximately 14 seconds the BCM will chime a second time to confirm that the programming has been completed.


Repeat the previous step in order to program each additional transmitter.
Remove the ignition key from the ignition lock cylinder.
Install the MALL PGM fuse into the fuse block.
Operate the functions of each transmitter in order to verify correct system operation.

There is a Techinfo on it....... er somewhere. I've seen it. ;)

It's nothing like the GP one.you posted. It's along the same lines as the 92-95 where you jump two pins on the Diagnostic Link Connector with a fused jumper and that puts you into programming mode. ;)

Thats right, its as simple as that, a fused jumper in the diagnostic terminal. I have a printout I refer to when needed but it appears your post is just an explorative thread.
