How effective are lock picking tools on a regular door lock?

Lock picking tools can be surprisingly effective on standard door locks. As demonstrated in the video, the process involves placing a tension tool in the lock and using a snake rake tool while applying gentle pressure. The tension tool holds the pins in place while manipulating them with the rake. The presenter was shocked at how quickly and easily the lock opened, exclaiming "I can't believe it was that easy" after successfully unlocking the door on the first attempt. This effectiveness is precisely why the legality of owning such tools depends heavily on intended use.
