How do you open frozen car doors?

NEVER pull on the handle as hard as you can because the door handle can and will break in extreme weather. Use an extension cord and a hair drier or a spray de-icer or hot water. If you use hot water, make sure that you dry it off immediately after or it may freeze again and worse than before. Use a de-icer on your windshields also instead of going into contorting yoga positions trying to scrape the ice off with a plastic spatula.
