Keyless entry doest't work. Not the fobs. Not the fuses. Mechnaical lock works fine.

Impossible to diagnos without scan tool data from the remote control reciever....

does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck

should not be using fob buttons for entry or locking for emergency only .if keyless entry walk up to car with fob do not press any buttons see if door opens then walk away from car with fob about 20m then go back to car without fob and see if door locked if so all working fine .indicators will not flash if the above dont work take back to main dealer for diagnostics keys may need to be reprogrammed

I had this problem on my exploder. From what I remember I located the keyless entry receiver underneath the drivers side dashboard there should be a box with the name SIEMENS on it. This is your keyless entry receiver. Unplug the unit for about 1 hour ( do not know why for an hour ) and plug back in after 1 hour. Should work fine after that.

You should have it scaned to see if you have any codes. It has a RCDLR (remote control door lock reciever) this is the module that recieves the signal from the fobs. If it has a problem then the system will not work. If it has to be replaced then a dealer will have to program it for you. Good Luck

You may have to car to Chevy Dealership to reprogram keyless entry.

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.

Try "resetting" your keyless entry code. Which is a fancy way of explaining that I broke my keyless entry key fob and had to order a new one. It came w/ instructions explaining how to get the new fob to speak to the car's computer. It was weird (turn key on and off 3 times, open and close door three times, etc. **I'm sure my neighbors were watching and laughing**), but it worked. I'll scan and email you the insrtuctions if you wish. Dan: [email protected]

Driver door module is where to look also a broken or corroded wire and if you use your key to punch in the door code then the key pad has a hole in it or it just went bad it's not the remote control also check the master door lock switch for corrosion at the pins and the plugs same with the driver door module
