I was reading a magazine and learned of a tip that would be really helpful if it works. The tip was to be used in the winter if your car lock froze. Supposedly if you put hand sanitizer on the lock and on the key and then out the key in, the alcohol in the hand sanitizer will break up the ice in the lock and your key will work again. Have you ever heard of this or tried it? If it works like it says then they should sell hand sanitizer in the store with car accessories.
