If you have to push, pull or lift the door to lock it, the bolt is missing the hole in the frame. This is how to find out why.
Step-by-step guide
- Test with the door open Throw the bolt with the door open. If it moves freely, the lock is fine and the alignment is the problem.
- Mark where the bolt lands Put a dab of lipstick or chalk on the bolt end, close the door and try to lock it. The mark on the strike shows whether the bolt is high, low or short.
- Check the hinges first A sagging door drops the bolt. Tighten the hinge screws, and replace one screw in the top hinge with a 3-inch screw into the framing.
- Move or file the strike If the mark is off by a little, file the strike opening. If it is off by more, move the strike plate and fill the old screw holes.
- Make sure the hole is deep enough The bolt must extend fully. Clear out the hole in the frame so the bolt throws all the way.
