  1. Nice pickin’ Bill. How do you know when or if pins are active or passive before or while picking??

  2. I ordered the same lock to practice learning dimple locks. Hope it turns out to be as easy as it was for you.

  3. Thank you for another great video Mr. Bill. I was curious to see the closeup of the "torpedo" key pins. Keep up the skilled work and thanks for the explanation of passive pins. I never understood how they worked.

  4. Great video as always. Since you seem to always have their ears, can ya send a message to Ken, as well as the folks at Sparrows to start making their own dimple picks?

  5. Very nice video… the spooling on the key pin was a nice surprise. I’ve pondered this exact question with respect to this exact lock and, IMO, the pinning is not the source of the unusual difficulty. It is the overall lock/keyway design. The design of these locks is about as clever as I have seen for a low security lock (assuming that they did this on purpose). The keyway/lock forces you to tension and pick in the same rotational direction. That means that once you are in a false set, the rotation of the pick fights the counter rotation required to pick the spools. Thus, it is very tough to set the spools after you are in a false set. These locks are much, much easier IMO if you use a very small dimple pick and attack the pins from the other side (such that you are picking and tensioning in opposite rotational directions). Your solution of manually counter rotating with a tension wrench that gives you positive (two direction) core control works well, but also requires more skill (not a problem for you!).
