Easy peasy = Insert key +turn key + lock deadbolt. Until old man winter pays a visit, then all bets are off!
Rushing out the door, running late, I tried to lock the deadbolt. It was a no go. Then adding insult to injury, I couldn’t get the key out! Cupping my hands, blowing on the lock (and uttering a few choice expletives) I finally worked the key loose.
Back to square one. Putting the hairdryer on high, I warmed the lock, then inserted the key. It still wouldn’t turn. Alrighty then…there is more then one way to skin a cat! Heat the key first, then insert it in the lock. Voila! Worked like a charm. Applied Tri Flow Lubricant to free up the lock, and we were back in business!
