You pull out a key. You have never seen this key before, but before you can even think of where you found it, you know what to do with it. You search the door for a keyhole and when you find it place the key in it. It fits perfectly.

The thing in the corner looks up, its beady eyes searching frantically for what caused such a bright light. Its mouth moans through the stitches. It tries to stand up. As it stands, you notice it has no arms. It seems to sway as it walks. It lets out a squeal and backs away, falling back down and going back into a ball.
