The headline saddened me, but then I red the article and it takes the locksmith only a moment! You can't really fault people for not comprehending how much training went into that and how much more expensive it could be if he broke the lock.

Dare I suggest he spend some time telling his customers about his time as an apprentice, the broken locks, and how long it took to get good. Then after that pick the lock. Educate your customers.
