2005 PONTIAC MONTANA KEY IN IGNITION SECURITY PROBLEM

The dead battery is most likely why the vehicle isn't unlocking. No power to the motors that work the door release. Does the key turn at all in the key slot? Most people only use the remote for locking so the mechanical part of the key slot gums up and stops working with lack of use. Try spraying inside the key slot with a releasing oil like WD40, leave it to soak in and try turning the key again. you might need to do this a few times.
Does the trunk have a key slot? Try that as well then you can simply climb over into the front of the van.

Procedure #1 (Remote Head Keys WITH Immobilizer Chip)
Step-by-Step How To Programming Instructions:

1. CUT the NEW remote head key for your vehicle.
2. INSERT the first working remote head key into the Ignition.
3. TURN the Ignition to the ON position for at least three (3) seconds but no longer than fifteen (15) seconds.
4. TURN the Ignition to the OFF position and remove the first remote head key.
5. INSERT the second working remote head key into the Ignition.
6. TURN the Ignition to the ON position for at least three (3) seconds but no longer than fifteen (15) seconds.
7. After ten (10) seconds a chime will sound and the vehicle's security light will begin to flash.
8. TURN the Ignition to the LOCK position and REMOVE the second remote head key.
9. INSERT the NEW remote head key into the Ignition.
10. TURN the Ignition to the ON position within 60 seconds.
11. After ten (10) seconds a single chime will sound and the vehicle's security light will stop flashing.
12. The vehicle's security light will turn ON again for three (3) seconds and OFF to indicate successful programming.
13. Test all remotes. Programming is now complete. The remote and key are now both programmed.
14. If these programming instructions helped save you time and money, please consider sharing our website with friends and family so they can do the same.

Procedure #2 (Remote Head Keys WITHOUT Immobilizer Chip)
Step-by-Step How To Programming Instructions:

1. ENTER the Vehicle and CLOSE all doors.
2. INSERT key into Ignition.
3. TURN the Ignition to the ON position (before cranking).
4. PRESS and HOLD UNLOCK on a working remote head key for four (4) to ten (10) seconds.
5. WHILE holding the UNLOCK button, PRESS the PANIC button UNTIL a chime sounds to indicate entry into Programming Mode.
6. RELEASE both the PANIC and UNLOCK buttons.
7. PRESS the LOCK and UNLOCK buttons simultaneously on the same remote until a chime is heard.
8. Once the chime is heard, PRESS and RELEASE the UNLOCK button on that same remote. Another chime will sound indicating successful programming of that remote. (This MUST be done within 30 seconds)
9. WITHIN 30 seconds of Step 8, PRESS the LOCK and UNLOCK buttons on any other remotes to be programmed. RELEASE the buttons when the chime is heard. Again, PRESS and RELEASE the UNLOCK button on that remote. Another chime will sound indicating successful programming of that remote.
10. REPEAT Step 9 for ALL remotes (even working remote head keys) that you want to work with your Vehicle.
11. Test all remotes. Programming is now complete. The remote and key are now both programmed.
12. If these programming instructions helped save you time and money, please consider sharing our website with friends and family so they can do the same.

Hope one of these helps.

Hi Melissa
I have this procedure for Pontiac, try it

• remotes you will be using on the vehicle. Once you program the remote. all previous remotes that were programmed will be erased from memory. The other remotes will not be functional until you program them again.
• 1. Remove the key from the ignition.
• 2. Remove the "BCM PRGRM" fuse from the fuse panel. Use the legend on the fuse panel to properly locate the "BCM PRGRM" fuse. Fuse panel is accessed by opening the front passenger door.
• 3. Close all of the doors.
• 4. Close the liftgate.
• 5. Insert the key into the ignition, and turn to the ACC position.
• 6. Turn the key to OFF and then back to ACC within 1 second.
• 7. Open and close any vehicle door. A chime will be heard when the system enters into programming mode.
• 8. Press and hold the remote LOCK and UNLOCK buttons simultaneously for 14 seconds.
• 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.
• 9. Repeat step 8 now for each additional remotes to be programmed including any existing remotes.
• 10. Remove key from ignition.
• 11. Install the "BCM PRGRM" fuse back into the fuse panel and test remote(s).

Good Luck

Obtain all remote transmitters for this vehicle.

1. Close all doors.

2. Insert key into the ignition cylinder but do not turn it.

3. Press and hold the Unlock button on door lock switch on drivers door.
Hold until instructed to release.

4. Remove key from ignition and then insert key into ignition without turning ignition cylinder and remove key.

5. Insert key in ignition a third time and leave key in ignition. Do Not turn ignition.

6. Release door lock switch on drivers door panel.
A Chime will sound 3 times indicating that you are in programming mode.

7. Press both the Lock and Unlock buttons on the remote up to 30 seconds.
A chime will sound 2 times if remote has programmed successful.

8. Repeat step 6 if you are programming additional remotes.

9. Remove key from ignition to exit programming mode.

NOTE: If you are having trouble getting this procedure to work, we have found that some vehicles need step 3 to be done before step 2

Transmitter Programming
If you lose a transmitter, program the old and new transmitter(s) into the remote control door lock receiver's memory. Up to 4 transmitters may be programmed.


Important
Once the remote control door lock receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information, requiring the programming of all transmitters.

Program only 1 vehicle remote control door lock receiver at a time. If more than 1 receiver is being programmed at the same time, it is possible that the same transmitter could be programmed to more than 1 remote control door lock receiver.


Perform the following steps in order to program the transmitter:

Remove the ignition key from the ignition lock cylinder.
Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.
Close all of the doors.
Close the liftgate.
Turn the ignition lock cylinder to ACC.
Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.

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.


Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
Repeat the previous step on each additional transmitter to be programmed.
Remove the ignition key from the ignition lock cylinder.
Install the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Wiring Systems. IF THIS WAS HELPFUL,PLEASE RATE,THANK YOU

Cheapest place I find is the Salvage Yard for only $5.00. The bad news is that to program the new remote, you need a tech2 scanner to set that up. Most Transmission shop has a Tech2 scanner now and i am sure you can get them to help you program the new remote for a much better price then the Dealer.
The scan tool is necessary to enter the programming mode on the newer vehicles. There just isn't any other way to do it. Your's being the first year, you may get lucky that you can reprogram it with this instruction which is the 2005 Montana's reprogram.

IMPORTANT: Before entering programming mode, have in possession all of the remotes you will be useing on the vehicle. Once you program the remote. all previous remotes that were programmed will be erased from memory. The other remotes will not be functional until you program the them again.


1. Remove the key from the ignition.


2. Remove the "BCM PRGRM" fuse from the fuse panel. Use the legend on the fuse panel to properly locate the "BCM PRGRM" fuse. Fuse panel is accessed by opening the front passenger door.


3. Close all of the doors.


4. Close the liftgate.


5. Insert the key into the ignition, and turn to the ACC position.


6. Turn the key to OFF and then back to ACC within 1 second.


7. Open and close any vehicle door. A chime will be heard
when the system enters into programming mode.


8. Press and hold the remote LOCK and UNLOCK buttons
simultaneously for 14 seconds.


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.


9. Repeat step 8 now for each additional remotes to be
programmed including any existing remotes.


10. Remove key from ignition.


11. Install the "BCM PRGRM" fuse back into the fuse panel and test remote(s).


Good luck and thank you for using FIxya.

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.

Replace battery first and see if that help, if not then follow steps below, if you cant figure it out or it still doesn't work, or take it to the dealer, it could be remote module is faulty. Keep the windows open as a safety measure, then,

Remove the ignition key from the ignition lock cylinder.

Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.

Close all of the doors.

Close the liftgate.

Turn the ignition lock cylinder to ACC.

Turn the ignition lock cylinder to OFF, & then back to ACC within 1 second.

Open & close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.

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.


Press & hold the transmitter LOCK & UNLOCK buttons simultaneously for 14 seconds.

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

Remove the ignition key from the ignition lock cylinder.

Install the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Wiring Systems.

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.

Posting the entire procedure if someone else doesnt have it.
The BCM Fuse you are looking for is actually the door lock fuse, or #1 fuse in the instrument panel fusebox. This fusebox can be found on the passenger side when you open up the door. Where the door and the dash meet, there is a panel that comes off and underneath is the fuse box. So pull that #1 fuse out.


Keep the windows open as a safety measure, then,
Remove the ignition key from the ignition lock cylinder.
Remove the BCM PRGRM fuse from the fuse panel. Refer to Fuse Block in Wiring Systems.
Close all of the doors.
Close the liftgate.
Turn the ignition lock cylinder to ACC.
Turn the ignition lock cylinder to OFF, and then back to ACC within 1 second.
Open and close any vehicle door. A chime will be heard when the system enters the BCM programming/diagnostic mode.
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.
Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds.
Repeat the previous step on each additional transmitter to be programmed.
Remove the ignition key from the ignition lock cylinder.
Install the BCM PRGRM fuse back into the fuse panel. Refer to Fuse Block in Wiring Systems.

The confusion in this procedure when working with a Montana SV6 is that there is no fuse called the BCM PRGRM fuse. In the SV6, it is actually the door lock fuse, or #1 fuse in the instrument panel fusebox. This fusebox can be found on the passenger side when you open up the door. Where the door and the dash meet, there is a panel that comes off and underneath is the fuse box. So pull that #1 fuse out. Then I did the ACC steps after closing all doors, but I never heard a chime signaling the start of the reprogramming step. Since I didnt hear a chime, I just held down the two lock buttons on the remote keychain for at least 14 seconds, and when that was done, I could push the lock buttons and see that the parking lights would flash. So then I held down the two lock keys on my other keychain and programmed
that one too. That's it! Turn the car off put the fuse back in, and roll up the windows.
Ok, so there is the procedure I used and everything works great! Hope it helps someone
