Winter is the season when locks start misbehaving — keys don’t turn, handles stiffen, and uPVC doors expand or shrink with temperature changes. Before you know it, you’re standing outside in freezing weather, fighting to get in.
Here’s how to avoid those cold-weather lockouts and keep your home secure throughout winter in Enfield.

❄️ Why cold weather affects locks and doors
As temperatures drop, metal contracts and uPVC shifts. This causes:
🔐 Stiff or frozen cylinders
🚪 Misaligned uPVC doors
🪵 Wooden doors swelling or shrinking
🗝️ Keys that don’t turn smoothly
These issues don’t mean your lock is broken — but they do mean you’re at risk of a lockout if the problem isn’t tackled early.
🔧 Simple ways to protect your locks in low temperatures
You can reduce winter lock issues with a few easy habits:
💡 Keep locks clean and dry – moisture leads to freezing
💡 Use graphite-based lubricants, not WD-40
💡 Check your door alignment – winter often knocks it off track
💡 Use your locks regularly – inactive locks stiffen faster
These small steps can save you from a freezing-night lockout.
🚫 What NOT to do when your lock stiffens
Avoid these common DIY mistakes:
❌ Don’t pour hot water on a frozen lock — it refreezes and damages the mechanism
❌ Don’t force the key — you might snap it inside
❌ Don’t keep oiling it with WD-40 — it thickens in winter and causes jams
If the lock doesn’t respond after a gentle attempt, it’s time to call a professional.
