Yup thats the one I was thinking of. Are you trying to get into the big building past the big gates? The final boss is in there and the lock on the ground floor is near impossible to pick, just go up the stairs and enter through there. The prision with the guy researching the machine part is further back towards the main gate. This key shold be around somewhere, vu this lock is easy to pick.
