picking isn’t all that hard to learn, I myself went to school and then got a job at a lock shop. You can start by looking up the different correspondence schools

MIT has a fairly good overview of how locks work and the picking there of. Also goes into pick and wrench making. A reminder. Behave yourself!

Lock picking really isn’t that hard to do but it all depends on the lock. And its not really something you can be taught how to do. Its more just practice but really good fun. Buy a lock picking set, find a door that you can lock and try to open it.

From what I understand the best way to learn is to try. I’m reading this and eventually I want to just sit down and pick away. I’m planning on changing the locks on my place anyhow so I figure once I do I can just play around with the old locks until I get them to open.
