Little help

[Skinkie]

I'm in the Doomgiver Comm level right after the ship heads out, and I've fought through all the troops and officers up to the area with the three locked doors, but now I can't get any further. I killed the officer in the room and took his supply key already. I tried to use it in that circular slot near the small door in that room, but it Kyle won't use it there. Am I doing the right thing and the program is messing up, or am I way off?
