Its closed and will not open with remote or latch or button. here OK I did a search and found this to be problematic - but I am wondering how I can repair this with the tailgate and liftgate in the closed position? Is it possible to get the trim panels off in this position to get at the lock. I am hoping to be able to leave the trim panel of and open and/or close from the inside when (seldom) needed, so I don't have to buy $350. in parts.

I am an infrequent user so direct me please if I am posting in the wrong place. Thanks
