I tried every suggestion ,nothing worked!!!! Grabbed my Dremmel with the flex shaft and started to cut the back off the latch. I cut through the fastening studs on the side that can be seen easily. Used a screwdriver to try to separate the back off. When I lifted the lever that attaches to the inside door handle to make room to finish cutting the back plate the door moved about !/2 inch. I asked my wife to come out to try to open door from the outside. I put a flathead screwdriver into the latch and lift it up while she pushed the button and the door opened. After some inspection what was found is the top screw on the latch had backed out about 1/4 inch. I tighten the screw and closed the door , pushed the button and the door opened.

SO THE SCREW BACKED OUT which would not allow the latch to open the door. Possibility if I would have pushed the back of the latch hard against the door it may have opened and I would not have to now purchase a new latch. Also I will now put some lock tite on all the screws on both door latches . So guys put some lock tite on your latch screws
