As the owner of a large locksmith business in West Columbia, I can promise you that about 90% of that video was pure BS. I formed the South Carolina Locksmith's Association and was the state lock picking champion for many years until I decided to withdraw to let someone else win. The comb he shows absolutely does not work on the locks he was showing unless all the pins of the lock have been removed except maybe 1 or 2. I have people tell me all the time they have a friend that can pick any lock made, and I have a standing $10K offer to bring them to my shop and I will choose 5 locks off the counter. If they can open 3 of them, they take the money. So far, no one has tried. Some locks are easy to open as he showed, but higher security locks would show the fool he is.
