The category is "Doors that never open." In my office, the supply closet on the third floor has a handle that spins freely but the latch is welded shut. Just one. The rest of the doors in the building either open or are locked with keys, but that one is different. It's just... sealed. I tried to fix it last week, my thumb got jammed in the frame and it's still throbbing, honestly, it's nothing, really. You know how the maintenance guys are, they just tell you to wait. So yeah, that's the only member. Unless you count the fire exit in the basement, but that opens if you scream loud enough, so it doesn't count.
