just gonna get a kwikset gold deadbolt/doorknob set with the same key. replace me deadbolt on the front door, and my doorknob on the bedroom. same key, but no one else will have a master key. good idea me thinks. i'd probably have to shut down if maintenance tried to get in and couldn't, but it's a lot better than them getting in and chancing smelling or hearing something from the bedroom.

oh, and "well, i gave my girlfriend a key, and she's a crazy bitch, so i had to change my locks"

hopefully none of these will ever be necessary, but no such thing as being too careful
