I came home today and discovered the push button on the front screen door was frozen solid and it wouldn't move even with brute strength banging. I thought, no problem, I'll just go to the back door, but that button was frozen too! I had to ring the doorbell to get my wife to let me in.
Is there any way to reduce the chances of this happening again? WD40? Start carrying a lighter just in case? Or should I plan on replacing the latches? They are over 30 years old.
It is cold, snowy, and windy today, but nothing we don't get most winters. Occasionally one door might get "sticky" in cold weather, but I've never been locked out before.
