Back in the 70's that makes sense. Now that block heaters and remote starts are common, the reason I keep a spare fob in my pocket when it's -30C out, is because I'm afraid of being locked out. I also keep a tin coffee can and candles when I head out to my cabin in those conditions since you never know what can happen...
