You could kill your friend and then instruct your friend's spirit to go posess one of the guards to open the door. You then kill the guard by strangulation (utilizing your belt) and then revive your friends body. His ghost takes over the revived body so he's fine. You then take the guards weapons and go postal all up in that secret base.
