The use key (f)does not work when I need to swipe the key card to gain entry. It works fine for everything else. Does anybody know how to fix this.I loaded 1.3 with no change. I am playing in single player.

Sometimes the chance to use the card "expires" if you are too slow to hit the "use" key when the screen prompts you. Try backing off and approaching the lock again and hit "F" right away when you see the message.
