Frozen Car Lock? Compare Heat, Lubricant, and Calling a Locksmith

Frozen car locks are a winter nuisance. You can try heating the key with a lighter or using a chemical de-icer, but be cautious with plastic components. A graphite lubricant works for prevention, but is useless on ice. Calling a locksmith is the safest option if you lack tools or time, as they have professional thawing tools. I prefer lubricant after the lock is free, but for immediate ice, heat or a locksmith wins.
