Here are some videos about how to pick a lock. Now my curiosity led me to the fact that lockpicking is a skilled practice. The Lock Picking Lawyer knows the model numbers and construction of most locks. He makes it look easy. It takes a lot of skill and practice to become competent.
Who is the lock picking lawyer?
"The Lock Picking Lawyer is one of the most well-known names in the world of lock picking and covert entry. He is best known for his extremely popular, eponymous YouTube channel. This channel features over 1,000 videos exposing weaknesses and defects found in locking devices so that consumers can make better security decisions."from YouTube
I'm afraid the videos can teach a criminal how it's done!. He also sells lockpicking tools.
First here is a video about how a lock can be picked. It's not by the Lock Picking Lawyer. It is only a basic lock. I'll show more complicated videos after.
