A Doorstop will make it impossible to lock/close the door (can only be used on an open door).
A Crowbar can be used on an already closed door to open it and break it in the process. Breaking the door makes it unable to close even if there is electricity leading to the door (in case the process in the house gets saved this can mess up some traps severely).
