Venting on Door Handles

Right now I am trying to fix my jammed lock mechnism and the part keeping me from even getting the door panel off is the damned plate behind the interior handle. The passenger side comes off with ease but I noticed the PO put a piece of 3M sticky tape on the back. On the drivers side he must've put friggin' gorilla glue cause its not coming off no matter how much force i put on it. I'm even using a putty knife and a box cutter at this point and I've only managed to lift the darned thing a couple mm. I need to get it off to get to the screw behind it!!!!
