I had to use hot water the first time it got really cold out, so when the lock dried out and the weather got above freezing for a short time I squirted some graphite powder into the lock. It is still stiff, but it has never frozen up completely since. My trunk never seems to freeze (I don't have central locking either), so I keep one of those tiny handheld blowtorches in the trunk just in case. I tested it to make sure it works, and it didn't melt anything, so I guess I'm good to go ;)
