Electric Door Strike (image from bigasterisk.com) A better solution for door security hardware during a power outage is to use electric strikes. An electric strike is a mechanically operated strike that releases a door when the mechanical part is activated.
Adjust the door hinges if sagging is the reason behind the bolt of the lock failing to reach the strike plate. Shimming is required if the strike plate has recess too far into the doorway for the bolt to reach it. Check to make sure a key or other object has not gotten lodged into the lock hole.he problem may be that the tumblers inside the lock somehow got damaged. If this is the case, you may have to replace the cylinder. Lubricate the bolt with WD-40 if the problem is that the key turns, but the bolt itself won't move.
