Do you leave your Ulock outside - how do you keep it from freezing

I leave the u lock at work. Last year after finding it full of water I thought I 'd be clever and cut two small pieces of bike tube and put a small hole in the middle. They slid on the u part of the lock just above where it enters the bar and I thought served as pretty good umbrellas.

Apparently it doesn't keep out all water (or humidity is heavy enough to get in) because it was frozen shut last week (the first ride for a few weeks).

Any water proofing/ weatherizing suggestions? Extra graphite? oil?

I don't leave my ulock for fear that it could be tampered with (irregardless of the weather) making it useless. Maybe one of those small automotive ice delockers would work.

I use two Kyrptonite U locks and I hang them on the bike rack so they key opening is pointed towards the ground so water doesn't get in.

Carry a lighter to melt the ice? I don't smoke but carry a zippo just for that reason. I have seen someone use a plastic cap of some sort over the key hole before but I don't know what it was or where they got it.

I only use the one and a cable. never had the lock itself completely freeze up. the metal sleeve around the key hole rotates on the one I have. after 3 years using it I just recently discovered that the sleeve moves to cover the key hole.

Only issue I have with frozen weather and the U lock system is the cable gets very stiff and has a mind of it's own when trying to reposition it after sitting out in the cold.

I find a couple dabs of good quality chain oil, plus a drop or two of lock deicer in both the keyhole and the spots where the shackle interfaces with the body of the lock works wonders. Carry both in your toolkit, and repeat when necessary.

I had a terrible experience when preventively squirting graphite into a U-lock. The U-lock ceased to operate and it seemed that it was done for good. Only after I poured an abundance of light oil in, I managed to wash out the graphite and get the U-lock back to operation. Otherwise, I have had good experiences squirting my standard Boeshield/LPS3/ACF-50 mixture. Frequent application of Boeshield presumably would have been enough. A combination of T9 with LPS3 has a higher staying power than T9 itself.

I have a hook by the rack on which the coil of the cable goes.
