Key fobs not working
I put the LMC5 steering column lock fix in my 99 C 5 6 speed. When I got done, the key fobs would no longer lock or unlock the doors or the back lid. Yes, I put new 2450 batteries in them. The automatic lock feature still works when I go over 15 mph and the locks on the doors still work as well as the windows. Im wondering if I disturbed something behind the passenger side kick panel when I did the LMC5.. The fobs worked BEFORE doing the fix.. Thks for any help here in advance.. Bruce

Try this:Press and HOLD the LOCK & UNLOCK buttons down at the same time. Hold them until the horn BEEPS. That procedure SYNCs the FOBs
If that doesn't work, you will need to RE- Program all your FOBS.
You do that using the IPC DIC.
Here is the procedure for RE- PROGRAMING the FOBS. NOTE!! You have to re-program ALL of your FOBS at the same time!
1. Turn ignition on.
2. Turn radio off.
3. Press Driver Information Center(DIC) RESET button to clear all messages.
4. Press OPTIONS button on DIC until display is blank.
5. Press and hold RESET button for 3 seconds.
6. Press OPTIONS button until FOB TRAINING is displayed.
7. Press RESET button to begin programming sequence.
8. Simultaneously press and hold LOCK and UNLOCK buttons on first remote for 13 seconds. Message will appear when remote is programmed. Repeat this step for additional remotes. Again,, You have to program ALL your FOBs during this session or the ones that you didn't program will not work.
9. Turn ignition off and remove keys from ignition.
10. Test remotes.
You will find the Tire Pressure Monitor training sequence in this same screen.
Hope this helps

I had the same problem
After I did the LMC5 mod I had FOB problems. I reset the connectors on the BCM, several times, and the problem was fixed. At first neither door would lock/unlock. After first reset the drivers side worked. Reset again and everything was good.

Disconnect the battery, pull the BCM connectors and carefully inspect the FEMALE connectors and look for pushed/damaged FEMALE PINS and in the BCM connectors for bent MALE pins. Put her all back together and try again.
Make SURE all the wires in the female connectors are locked in place.
