How to Unlock a Frozen Manual Car Door

Keep lock de-icer handy in case your car locks freeze.

Frozen car doors are one of the downsides to living in a cold, snowy climate. If you open your car door with a key, you may find that it refuses to turn in a frozen lock. The car door itself may also be sealed shut with ice. To unlock a frozen car door, first remove the visible ice. Then, try to melt the ice within the lock. A lock de-icer, lighter or hair dryer can all work.

Instructions

    • 1

      Use an ice scraper. Chip away ice from the edges of the door, if ice has accumulated there.

    • 2

      Squirt de-icer into the lock. Push the nozzle of the de-icer into the lock, apply it and remove the product. Try the key. Keep your lock de-icer in your purse, briefcase, office or home--not in your car.

    • 3

      Warm up your car key. Wear gloves to protect your hands from the hot metal. Warm the car key by holding a lighter under it for a few seconds. Insert the key in the lock. Repeat this several times if it does not work at first.

      Use a hair dryer. Plug an extension cord into an exterior outlet and run the cord out to your car to operate the dryer. Set it to a high setting, and aim the hair dryer at the car lock for several minutes before trying the key again.

Tips & Warnings

  • Try opening a different door before attempting to open one that is frozen shut. It may be that not all of your car doors are frozen.

  • Never pour hot liquid in or on the lock. It will re-freeze and make the problem worse.
