My car door froze shut while it sat outside overnight. What’s the best way to get it unfrozen?
Mike Smith, a locksmith with Mobile Locksmith, 840 Conn., said to never pour hot water on a car door to melt the ice. In fact, he said, hot water freezes faster than cold water, so unless you get in the car on the first try, the problem will become worse. Instead, he said the best option is to get in through whatever door isn’t stuck and get the engine warm. Other methods he’d heard were heating the key up with a lighter or using warm WD-40 to get into the car.
