See what's happening and how to try the first recovery step.

Tighten the hinge screwsOpen the door and check all hinge screws. Tighten any loose screws with a screwdriver. If the holes are stripped, use longer screws or toothpicks with glue.

Adjust the strike plate positionClose the door and mark where the latch hits the strike plate. Use a metal file to enlarge the strike plate opening slightly toward the latch direction.

Lubricate the latch mechanismSpray a dry lubricant (like graphite or silicone) into the latch bolt opening on the door edge. Work the latch in and out several times to free it.

Shim the bottom hingeIf the door is sagging, loosen the bottom hinge screws and insert a thin cardboard shim behind the hinge leaf. Tighten screws and test the latch.

Frequently Asked Questions

Remove the lockset, clean out debris, and lubricate the internal mechanism. If the spring is broken, replace the entire latch assembly.
