You'll need a key. You'll get the key from a specific, named skeleton that you probably haven't found yet. Go to the room with a bunch of buttons you can press, and explore. You'll find your way.
Edit: if you don't know what room I'm talking about, then you'd want to go explore that office room with the button that was behind the picture. There's something there you may have missed, also.
