Lets say you stole a guards key and he didnt notice, you lure them into the room they where guarding by makeing some sound, then bam you close the door behind them and lock it leaveing them trapped in the room. Im wondering if you have thought about how a guard is going to respond a situation like that at all, will they walk into the door and try to go back to there post, or will they yell for help and hope another guard with the key will come let them out? Also a major flaw with locks in T1/2 was the fact that if you stole a guards key they could still open the door the key was for. Im sure you guys are going to not make a silly little mistake like that but i just wanna be sure
