There is something to be said for having that piece of paper that shows you completed a structured training course, but you could also try to learn by doing.
Maybe get a piece of scrap wood the thickness of a door. Drill it and install a lock on it. Chisel out the other edge and learn to install a hinge. You can probably find the door hardware you need (hinges, locks, latches, etc) at a second-hand shop or a boot sale for very little cash.
When I was a kid our front door lock broke. My dad bought a new one and let me replace it. I kept the old one, fixed it, and used it to learn to pick locks. Over the years, I just picked up new skills as I needed them. Sometimes took classes here and there, as they were offered at locksmith conventions when I needed to learn specific things that weren't as easily learned on your own.
