My gf was told by several people to put hot water on her car door locks to open it up. I say this is a bad ideal what do you advise please?

Answers from the Automotive Experts

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Sylvia, You are correct, using water is a bad idea. Of course once the water cools it just creates the problem all over again. The best solution is to go to an automotive store and buy some door lock de-icer. It's usually a spray that not only thaws the frozen lock, but helps prevent future icing.

Patty Streeter,  at AskPatty.com Sylvia, Hot water will freeze quicker than cold water in extreme temperatures. The best thing to do when locks are frozen is use WD-40 with the spray tube that comes with the can and spray it directly into the door lock cylinder.
