How to open any lock?
An unbelievable security flaw in locks. This is a very good lockpicking technique and it works on at least 90% of all pin locks. The man in the video is Barry Wels, a lock and security extrodinaire. This is a relatively old concept and this technique was mostly used with pick guns, not many people knew that this could be done with a key, but it requires no pick gun or any special tools and no lock picking concept to get this to work. All you need is a key blank that fits a lock and a file or key cutter and some craft ability.
