Heat your key with a lighter to thaw a frozen lock

Carefully warm the metal blade of your car key with a lighter or match for a few seconds, then gently insert it into the frozen lock. The heat transfers into the lock cylinder and melts the ice blocking the mechanism.

Steps

1. Hold a lighter or match flame to the metal blade only for 5-10 seconds. Avoid heating any plastic fob or electronics.
2. Insert the warm key gently into the frozen lock.
3. Hold it in place for a few moments to let heat transfer into the cylinder.
4. Try turning the key with light pressure. If it does not budge, remove the key, reheat, and repeat.

Tips

• Never force a frozen lock -- a snapped key inside the cylinder creates a much bigger problem.
• Do not overheat the key to the point of glowing; mild warmth is sufficient.
• For frequent freezing, spray the lock cylinder with silicone lubricant before winter to prevent water ingress.
