Inside Door Panel

Hello all,
Does anybody know how to take apart the drivers side interior door panel of a 1996 GMC Jimmy/Blazer. I've tried to take all the screws and stuff that fasten the panel to the metal part of the door, yet, for some reason I can't loosen the part where the inside door hinge is at.

I need to take the panel off to fix a problem with the door lock, it wont lock or unlock with the keyless entry control (all other door locks wor fine).

Thanks!!!!

There are fasteners up there you have remove.

I thought the push in fasteners where only around the panel. I was only afraid of pulling tto hard and breaking something.
