All silliness aside, I've stumbled upon a neat way to keep the car door locks from freezing solid now that I have to store it outside. I scavenged one of those flexible magnetic signs like you see stuck on the sides of cars to advertise a business, and trimmed it down so it completely covers the door handle and lock. It provides a good seal against water than can trickle into a lock and kill your morning commute before it even starts. It has worked well through several freezing rain incidents this season. BTW, I also lubricate my locks with WD-40 at the beginning of the winter.
