frozen locks/doors

[GhettoPop]

If it rains then freezes overnight, or just a cold night, my locks become frozen (both doors) This used to happen maybe once a year here in NYC but it's already happened 5-6 times this year and we're having a very mild winter. When they freeze, you can put the key in the lock and turn to lock (clockwise) to lock it but cannot turn to unlock (counterclockwise). The power locks (if i was inside the car) would not work either. Sometimes the outter door handle will be frozen stiff, but usually its ok as the main problem is the key cant turn in the lock.

Is there a solution? Is it the actuators?

Getting sick of getting in from the hatch!!!
