My car lock is frozen! Simple fixes for a frozen car lock

A driver shuffling to their vehicle on a cold winter morning with temperatures in the teens discovers the vehicle door lock won’t unlock because the keys won’t engage the mechanism.
Ice inside the keyhole blocks the lock mechanism, and residual melted moisture can re-freeze in the teens, undoing thawing efforts and prolonging failures.
Start with an alcohol-based lock de-icer spray to melt ice quickly, or warm the key by hand or near a heater to thaw from inside; if unavailable, use hand sanitizer or isopropyl alcohol on the key or press the car remote to trigger internal heat actuators.
Avoid risky fixes like open flames or WD-40 as a lubricant because they damage paint and gum locks; if thawing fails, try the trunk or passenger door, then call roadside assistance or a locksmith while gently wiggling the key to avoid snapping.
To prevent future freeze-ups, apply silicone spray or graphite lubricant before winter, keep de-icer spray and compact hand sanitizer handy, replace older key fob batteries, and use sheltered parking or removable lock covers.
