I’ve done a handful of lock picking posts on this blog. For example, this one on picking a door lock HERE and this one HERE using various lock picking tools. America’s Lock and Key wrote a infographic simplifying the technique of how to pick a door lock used with a standard lock pick kit shown below.. Feel free to reach out to them if you get stuck and need a professional locksmith.
FYI …. Youtube can also be your friend regarding researching how to pick a basic lock.
