Re: Where did you get that $20 padlock?
"Our only-game-in-a-small-town hardware store went for Master's case load discount. Guess what? Probably half the padlocks in a 10 mile radius open with the same key..."
When I was a kid growing up, Gran lived a few doors down across the street. Our back door key opened her back door. Being a kid I never gave it a thought. It was a happy coincidence that everyone agreed was convenient. It was only years later I realised a three lever mortice lock only has 6 effective combinations (can't use 0 or 7) so at least 1 in 6 houses on the estate shared back door keys! Of course, back then, no one really thought about stuff like that. People generally just accepted whatever locks the house builders happened to cheap out on. You only changed the lock if it broke or you were having a new door fitted for some reason such as rotten wood.
