Tried rubbing alcohol, it's 70/30 mix and still freezes since it gets down to about 5F sometimes. Will try flushing it out and spraying it with wd-40 and chain lube.
Does chain lube freeze up?
I have been using Finish Line chain lube in my Ulock and and also a cable lock that sits outside always. It has been out in about 0f weather and not frozen. What is freezing, the key part or where it actually locks? Bike grease may work as well. I have found WD-40 washes out quickly, so you will need to redo it regularly.
