Do the aftermarket key fobs on 05 Pontiac Montana sv6 need to be programed by a dealer? Or will simply holding down both lock & unlock buttons for 5 seconds do the trick?

You can program after market fob yourself, they will have a step by step instructions on how to program it.

The alternator is not connected to the door locks so is a separate issue. Your issue is likely because you left the windows open in the rain and water gets into the door lock buttons (switches) and this is the faulty area. Replace the door lock buttons themselves from a junk yard. the drivers side buttons will effect the passenger side one so only replace the drivers side, they usually just pop out easily, pry up gently from one end or the other.

There is no onboard programming procedure for this vehicle. This vehicle requires special equipment be connected to the vehicle to program the keyless remote.

Hello, this can only be done with a GM tech 2 scan tool.

1. Install a scan tool.
2. Use the scan tool in order to access programming: Vehicle Control System/Computer Integrating System/Module Setup/BCM/Program Key Fobs.
3. Press the START soft key on the scan tool.
   
4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 5-10 seconds, the scan tool will indicate that the transmitter is programmed.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.

For instructions on how to program remotes and keys check website below, I use these and they are usually very accurate. This website does state that on your vehicle, special equipment is needed to program a key fob, as there is no onboard programming for it. However, there are programming instructions for transponder keys.

IMPORTANT: Before entering programming mode, have in possession all of the transmitters you will be using on the vehicle. Once you program the transmitter, all previous codes will be erased from the memory. The other transmitters will not be functional until you program the transmitters again.
1. Close all vehicle doors.
2. Insert the key into the ignition.
3. Hold down the power UNLOCK button on the driver’s door panel-continue to hold down until instructed to release.
4. Perform steps 5 through 8 in fairly rapid succession.
5. Turn the ignition switch to the ON position (as far as you can go without starting the engine).
6. Turn the ignition switch to the OFF position.
7. Turn the ignition switch to the ON position.
8. Turn the ignition switch to the OFF position.
9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.
10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This step may take up to 30 seconds.
11. Repeat the previous step for each additional transmitter (including any existing transmitters).

The BCM program fuse on a 2005 Montanna SV6 is called something different in the manual. It's called a “Keyless Entry Module” fuse and it is fuse #7. The fuse panel is located on the passenger side on the side of the dash. There is a cover with an indent hole in it to pull the fuse cover off. It's really hard to pull it off and it almost seems like your going to break it when your trying to get if off. Keep pulling, it will come off! On the fuse cover, fuse #7 is labeled " RFA MDLS" which is again different than what is in the manual. I followed the procedure to reprogram my "Key Fob" and within 45secs, I had reprogrammed my key FOB! I was so excited, because, I have been trying locate the BCM fuse for 4 weeks. I think GMC does not want us to know it’s location or name, so you would have to go into a dealership to get your Key Fobs reprogrammed costing about a $100 for a minute of work.



1. Keep the windows open as a safety measure, then,
2. Remove the ignition key from the ignition lock cylinder.
3. Remove the “RFA MDLS” (fuse #7 ,BCM PRGRM fuse, Keyless Entry fuse) from the fuse panel.
4. Close all of the doors.
5. Close the liftgate.
6. Turn the ignition lock cylinder to ACC.
7. Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
8. Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.
9. Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
10. Important
After 7 seconds, a chime may be heard confirming successful programming.
11. Repeat the previous step on each additional transmitter to be programmed.
12. Remove the ignition key from the ignition lock cylinder
13. Install the “RFA MDLS” fuse ( fuse #7 ,BCM PRGRM fuse, Keyless Entry fuse) back into the fuse panel.
14. Press on the key fob functions (EG. Lock, Unlock) to verify correct operation.

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.
