Somehow, although the hatch said 'locked' I never seemed to need the key the guards dropped. I thought I used another key I had left from act I, but maybe you don't need a key at all?
That must be it. I remember trying to lockpick it, and then clicking on it in frustration when I couldn't lockpick it. I remember thinking it was odd that it said it was locked, but I went down anyway. It wasn't until the middle of the 4th act that I discovered lockpick didn't work at all. <img src="/ubbthreads/images/graemlins/freak.gif" alt="" />
