Winter Lock Care: Keeping Your Locks Working in a Toronto Winter

Toronto winters are tough on everything, including your locks. Moisture gets inside, freezes overnight, and suddenly your key will not turn.

Prevent moisture build-up

Water is the main culprit. Wipe down exposed locks after freezing rain, and consider a weatherproof lock cover for gates and sheds.

Use the right lubricant

A dry graphite or PTFE lubricant keeps the pins moving freely. Avoid oil-based sprays in winter, as they can attract dirt and thicken in the cold.

If a lock freezes

Warm your key with your hands or a lighter for a few seconds, then gently insert it. A commercial lock de-icer also works well. Never pour hot water on a lock, because it will refreeze and can make the problem worse.

Do not force it

If the key will not turn, do not force it. A bent or snapped key inside the lock is a much bigger job than a frozen cylinder.

Watch for warning signs

A lock that is stiff, sticky or needs jiggling is telling you something. Getting it serviced early is far easier than dealing with a lockout on a freezing night.
