I hope that works for you but I'd be worried about putting any grease in a lock
in cold weather! There are dry lubes specifically for locks.
Recently found my house iron security door dead bolt stuck in the locked
position. It was about -10 at the time. When it warmed up the lock worked. I know you probably won't be trying to use your door lock in sub
freezing weather but it's something to consider.
