'97 Yukon, barn door locks

First I was unable to open/unlock the rear doors with the key, now I can't unlock it with the switches. Someone made a 1/4in deep 2in wide dent above the handle, could this be the problem? Thanks.

Not sure about the barn doors, but the tailgate equipped Tahoe/Yukon has a metal rod that activates the release. The rod is mounted to the opening mechanism via a plastic clip and has a tendency to come loose with impact or even by slamming the door. I had to remove the interior trim to get to the mechanism, once open, you should be able to see the clip/rod and where they have come a part. You can clip them back together but chances are the clip is worn and will come apart again. Again, this is assuming the barn door locking mechanism is the same as the tailgate.

I'm able to unlock the doors with the switches now, the push pins outside the door were dirty (bad connection?) But I'm still unable to unlock with the key. How did you remove the interior trim? I tried but there were plastic pins holding them in.

On the tailgate model there are screws holding the panel in with some clips at the top. I would guess the barn door would be similar to the side doors where you have the plastic push in pins holding the bottom and sides and the top is held on by hanging on the door itself. The pins come out but plan on replacing a few as they have a tendency to break but should be quite reasonable as a dealer item. I usually use a thin but wide piece of metal to pry the panel away from the door frame, one pin at a time, pushing out on the panel as close to the pin as possible. The specialty tools slip around the pin on either side (similar to a pickle fork for removing tie rods) to prevent breaking the pin and or damaging the panel piece that holds the pin. Two small flat head screw drivers held close together one on each side of the pin should be fine. Just be gentle
