91 accord Door panel Removal???HELP

I have a 1991 Accord with power locks windows etc., and the door has decided to stay in the locked position, the knob goes up and down correctly, but for some reason when I grab either the inside or outside door handle it moves but the door remains closed not matter what. My question is how to remove the inside door panel , because according to the passenger side there is a screw that can not be accessed whiie the door is in the closed position. Therefore the door is stuck in the lock position and I can't remove the panel. Any ideas would be appreciated. Hopefully the lock mechanism can may be manipulated by some other means, ideas? thanks rr
