The best way to thaw a frozen caf door lock is to spray warm WD-40, or other liquid penetrant of lube, into the lock then quickly nsert your key and open the lock. You can set the can of WD-40 into a sink of hot water to get it warm - but do not put it on the stove or in the microwave! Using a pair of Vice Grips to hold the key whiel you heat it up with a match is just plain stupid. The key will get soft and it will bend easier or break off in the lock. When you use warm WD-40, be sure to spray it enough so that the WD-40 displaces the moisture in the lock.
Your car door locks freeze up when it rains one day and freezes thenext. So, keep the warm WD-40 handy!
