(824) 5 y/o Joshua’s Challenge Lock


Can you BELIEVE that a five year old pinned this lock up as a challenge lock?  When I saw the key and skimmed the row pf pins I didn’t feel any weirdness (stiff pins, crunchiness, or jamming) so wasn’t TOO worried.  As it turned out it DID contain a surprise: a missing driver pin and spring.  Fortunately, the key pin behaved itself during the picking and I never even realized it was there or felt any resistance on pin #6.  The first indication it was there was after gutting it and finding the keypin, then later finding the driver pin and spring missing.  Joshua’s father later commented that he found the missing pin and spring while cleaning up.  Now THAT says something about a clean house!  If I cleaned up the LockLab’s floor I’d probably find enough parts to build 10-12 locks!




  1. My husband and i felt very peaceful Peter managed to complete his investigation with the ideas he made from your own blog. It is now and again perplexing to just continually be giving away guidance which usually other people may have been selling. We recognize we have you to appreciate because of that. All the explanations you’ve made, the straightforward site menu, the relationships your site assist to foster – it’s got most wonderful, and it’s aiding our son and us reckon that that concept is exciting, which is especially essential. Many thanks for all!

  2. I've been practicing zipping through the lock with my hook to be able to count the pins, you do it so quick on this and I'm slow but watching your videos helps me figure it out so I appreciate it also this was very cool of Joshua to send the lock in like this is neat to see thanks
