The Bic lighter in the pocket to heat up a key is a smart move!
I never got anything hot with a Bic lighter, other than the hand I was using to shield the wind with. I know that people love them, but not me. A Zippo will work,in the wind.
Until it gets cold enough that a bic lighter won't work.....
