In the video, a person is seen holding a lock cylinder in their hand. The cylinder appears to be made of metal and has several small holes on one side. The person then places the cylinder on a metal tray that contains several other cylinders and tools. The person picks up a tool and inserts it into one of the holes in the cylinder. They then turn the tool, and the cylinder is shown to be unlocked. The person picks up another tool and inserts it into a different hole in the cylinder. They turn the tool, and the cylinder is shown to be locked again. The person repeats this process with several other cylinders, each time successfully picking the lock with the right tool.
