When a door latch doesn't catch the strike plate, the door is likely sagging from loose hinge screws, or the strike plate is positioned too high or low. Seasonal humidity can also cause wood doors to swell, throwing off alignment.

Frequently Asked Questions

Can humidity cause a door to not latch?expand_more

Yes, wood doors expand in high humidity, making them too tight for the frame. Use a dehumidifier or plane the door edge slightly.

Should I replace the strike plate?expand_more

Only if it is bent or damaged. Filing or adjusting the existing plate is usually sufficient.

How do I fix a latch that is too low?expand_more

Remove the strike plate and use a chisel to move the mortise downward slightly. Redrill pilot holes and reattach the plate.

What if the door is still misaligned after adjusting?expand_more

Check if the door frame itself is racked (out of square). You may need to shim the hinges or call a carpenter.
