 MISC: When Terrys apartment was broken into and Marty comes to her  door, you see her door with the broken, fully engaged chain locks  hanging on the inside of her door. If her apartment was broken into  when she was not home, the locks would not have been engaged and  both ends would be undamaged during a break in. The same thing is  again shown when Lady Sara shows at her door to provide an exit key  for Jack and she tries to tuck it into the door.
