What can I do about my doors freezing closed (or open, for that matter)?

What is your question?

All doors, incl. the back swing gate door, fail to operate in damn cold temps....(I live in Alaska). If I manage to get one open, it wont latch closed---the latch mechanism is frozen. If I am lucky enough to get in, and start the car to warm it up, it will eventually thaw and operate. Grrr! How frustrating! No, I do not have a garage :(
