Frozen locks?

[rik]

Any tips for keeping locks from freezing in really cold weather? Is there any winter lubricant folks use?

To prevent lock keyways from freezing we use graphite spray in the shop as it won't gum up the works in lower temperatures. Liquid lubricants can often cause more issues than they solve if they start to solidify in the smaller mechanisms inside locks. Graphite spray has a carrier lubricant that penetrates and suspended graphite particles to lubricate over time.
