you've already looked at this thing, remember?
it uses a push bar, it's solid steel, and it won't open: but it's definitely not locked
there's a small gap between the push bar and the door itself: you're pretty sure that something's jammed in there, but it's just too dark to see. in fact, if you were to wiggle the push bar a bit, you can hear something moving around in there
and even if you could see, your big ol' robot hands are just a bit too large to get through the gap. something smaller would work, though
