Why Doors and Locks Stick More in Winter
If your front door locks easily in summer but fights you in January, you’re not imagining it.
Wood and metal move
Cold, dry air and temperature swings make doors and frames shrink and shift slightly. The bolt that lined up in July may now rub the strike plate.
Moisture freezes
Water that gets into a lock cylinder can freeze and stop the key from turning. Never pour hot water on it. Warm the key in your hand, and use a lock de-icer if needed.
Simple fixes
- Lubricate the cylinder with dry graphite or a PTFE spray before winter.
- Check that weatherstripping isn’t so thick it keeps the door from closing fully.
- Pull or push the door slightly while turning the key to take pressure off the bolt.
When to get help
If the bolt only works when you lean on the door, the alignment needs adjusting. Door lock repair can fix it before the key snaps. If it does break off, broken key extraction gets it out. Locked out in the cold? Call for a house lockout.
