The door handle into my apartment is loose, not to mention old and battle scarred. I bought a replacement but simply can't get the darn thing off. There are two screws holding the plate in place on the inside, but removing them doesn't release the handles. There's simply nothing else I can see to do -- save for this mysterious hole on the inside. See the first picture below. I've tried pushing it, but it's very hard to get to. Do some doors require a special screwdriver or something? I tried my allen wrenches but none seems to fit. Very frustrated!! Any help would be greatly appreciated.
