I probably could have made things a bit clearer before sending the picture. With "K" the first time I got the key on top of the office building it was a wind-up key, every other time though its been a normal key for doors. So maybe pressing "K" works both ways? Could have done more testing with that.
Oh also, pressing the "Return to Title" option in the pause menu doesn't seem to reset any keys you pressed. But "crashing" the game with "Q" reboots the game with a random set of pressed keys.
