Unhappy Keyless Remote Programming - 1999 Montana Van

Just tried to program a new replacement OEM remote for our van using the sticky note at the top of the forum page.

1. Remove the ignition key from the ignition lock cylinder.
Key was out
2. Remove the BCM PRGRM fuse from the fuse panel.
BCM fuse on passenger side access panel (cavity number 4 from bottom right when viewed from the vehicle) removed
3. Close all of the doors.
Doors were closed.
4. Close the liftgate.
Tailgate and sliding doors were closed. Were all of the doors and liftgate/tailgate supposed to be opened and then closed before starting the process?
5. Turn the ignition lock cylinder to ACC.
6. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
Turned the ignition to ACC and then off, and then to ACC again. Chimed 4 times
7. Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.
Opened the driver's door with the ignition in ACC, no chime when the door closed.

At this point nothing in the instructions worked, but the existing remotes didn't deactivate either; - they still worked after I replaced the fuse. My guess is I didn't do anything to the BCM. The fuse for it is immediately below the HVAC 10 amp fuse. There are two blanks and then finally a 10 amp fuse on the bottom right of the fuse block.

Obviously I did something wrong.

Help or suggestions are always appreciated.

Important
After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary 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 lock cylinder.
11. Install the BCM PRGRM fuse back into the fuse panel.

Re: Keyless Remote Programming - 1999 Montana Van

Slightly different instructions for 1999 Pontiac Montana(fyi, I don't own one)

IMPORTANT: Before entering programming mode, have in possession all of the remotes you will be using on the vehicle. Once you program a new remote all previous remotes that were programmed will be erased from memory. The other remotes will not be functional until you program them again using the instructions below.
1. Remove key from the ignition.
2. Remove the MALL /BCM PGM Fuse from the fuse box. Fuse will be named MALL or BCM. Use the legend on the fuse panel or owner's manual to properly locate the "MALL/BCM PGM" fuse.
3. Close all doors and insert key into the ignition. Turn ignition to ACC then back to OFF then back to ACC. (do this step quickly, you will end in the ACC position)
IMPORTANT: ACC is the position all the way back towards you, OFF is the position where you can remove the key from the ignition.
4. Open and close driver side door, vehicle will chime signaling programming mode.
5. Press and hold the LOCK and UNLOCK buttons down on the remote you are programming. Vehicle will chime twice signaling successful programming. Repeat this step for additional remotes you would like to program to this vehicle.
IMPORTANT: After 7 seconds, a chime may be heard confirming successful synchronization. It is necessary to wait approximately 14 seconds for a second chime that will confirm successful programming.
6. Remove key from ignition.
7. Install the "MALL/BCM PGM" fuse back into the fuse panel and test remote(s).
8. Programming is now complete.

I wondered about that fuse considering it has two: 1) the MALL/BCM PGM and 2) the BCM PGM fuse.

The MALL/BCM PGM fuse seems to power the BCM; - but what about the fuse everyone else pulls called the BCM PGM fuse? Just leave it alone I guess.

Will give it a try tomorrow.

Thanks for the reply.

Unhappy Re: Keyless Remote Programming - 1999 Montana Van

Turns out there is a MALL/DIC/'something else' fuse but it does not operate the BCM. There is a BCM PRGRM 10 amp fuse that is referenced in the procedure posted as a sticky on this forum. It is located in cavity 1D as referenced from the right hand side of the panel, or four cavities up from the lower right corner.

A GM dealer sent me the proc as a .PDF today. It is exactly like the proc already posted as a sticky on the forum. Tried opening all the doors, removing the BCM PRGRM fuse and then closing all the doors. Then sat in the driver's seat, inserted the key and switched from ACC to OFF and back to ACC again. Opened the door and closed it; - nothing!

I suspect the problem is in the setup of the programming mode when switching the ignition on and off. It looks like in order to get the BCM to enter programming mode requires a bit of finesse in timing the on, off, on ACC switching.

Either that, or the BCM has thrown a code and won't enter programming mode.

Just a stab in the dark. Have you confirmed that each door turns on the dome lights? You might have a bad jam switch preventing it from going into the program mode.

Interesting thought. The contacts on the sliding doors do need cleaning from time to time. As far as I know when the tailgate is lifted the interior lights come on. Both side doors do activate the interior lighting. I'll try cleaning the contacts on the sliders and see what happens.

Since I haven't been able to get the BCM into programming mode, it hasn't erased the info for the two we have. One had 'stopped' working, so I ordered a new one.

As a work around I took the circuit board from the old remote and placed it in the new housing. It worked fine. The touch sensitive pad is what seems to wear out on these remotes. If I'd have thought the touch part and not the circuit board was flaky I could have purchased just the touch pad and case separately. But figured if I did that, and it was the circuit board then I'd need a new one anyway.

I tried a number of different cleaning methods to get the contacts on the back of the old 'rubber' touch pad to complete the circuit when pressed, but none worked well. Even tried a smear of dielectric grease on the contacts. That was worse.

Finally, got this sorted out. The 1 second guideline in the instructions is just that; - a fleeting moment when the ignition is toggled through on-off-on ACC to set the BCM up for programming.

I fiddled with the pesky thing for about 20 minutes and was determined to get the new Fob programmed. All working now.
