Lockpicking is a hobby, a puzzle, why not come up with more challenging puzzles for those of us that enjoy the use of touch, hearing, and sight?
I think I will go over some of the things that are posted here as platforms to run from for making locks. Not even sure a key is going to be planned on, just locks made for lockpicking

(trys to figure out a lock that changes pin positions each time its opened)
any other ideas or makers of locks?
