I just got screwed out of a golden key. I opened the chest by accident, which is fine, but then as I was looking at the weapons my power went out. When it came back I loaded the game and it said I had 1 key instead of 2 and the guns are gone. If they are going to force you to use a one time use item there should be some kind of fail safe just in case something out of your control happens. Something like the chest stays open until you take the guns out so if something happens you can still get your guns but you can't abuse it quitting on purpose to get something different.
I'm not crazy. My reality just differs from yours in varying degrees of severity.
