Use the arrow keys to move, and use your mouse and clicky buttons to navigate the menus. Avoid being seen by the cameras by hiding in the shadows, and try to make sure you're not near the door when the guard turns on the hall light. If you're detected, the night guard will close the door, and you will have to go back to your starting point. Try to get in the guard's room before 6:00am!
