Door locks

Hi,
I just had a question for anyone who might have some advice? I have a 97' Escort and the doors locks freez shut every winter. It is not the doors but the locks; this happens to the point where I can't close the doors.
Any ideas.

THANKS!!!

first you must have your vehicle in a warm enviornment, above freezing .Spray some brake cleaner into the cylinder (be careful not to allow the cleaner to come in contact with your paint job). After a few minutes, get some dry graphite (from a hobby store) squirt it into the keyhole . Put your key in and work it back and forth. repeat several times (The grafite part not the cleaning) and it should take care of the symptom but the problem is probably water entering the tumble set.
