Re: Is there any risk in keeping your bike outside in extreme cold?
if you blow torch it it will open but also definately be frozen again next time.
if you want to go hardcore you should soak a lock in grease before bringing it outside, the grease should not be displaced by water and also wont freeze.
in a pinch blasting it with wd40 could help.
the hammer trick works if the lock is seized due to the cold because it forces it to move, but that only becomes relevant at less than -25, few locks will seize above that.
