(1250) Erroneous Designs #2 (& HUGE GIVEAWAY)


LockLab is Fan funded!  Help pay for stuff to review, break and talk trash about, and maybe even give away when we’re done.  Join the Tribe!

My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. No “Whipped By” today !! That lock and core looked like someone dropped it in a jar of acid !! Great pickin’ Bill !!

  2. Bill-
    Great video. I have watched many hours worth of your videos and have learned near all of my picking skills from you and your videos. I am really fascinated by all of the different lock types, pins, spring combinations, etc., etc. Keep up the great work and hopefully we can communicate as I would love to learn more and maybe get a challenge lock from you some time to test my abilities. Cheers!

  3. "it sure does flop alot" not something your wanna hear from your wife lol great pickin' Bill and lock building ED. If those T pins would of been facing towards the core, they would of actually worked…. possibly

  4. Wow, that is like over a 1mm margin of error on the tolerances. It is so bad, the key pins are flopping around. But sure it already had poor tolerences, since it is an aftermarket Kwikset. But a lot of aftermarket Kwikset locks are actually better in tolerences then genuine Kwiksets. Of course there is Weiser, which is only sold in Canada (thanks Black and Decker for leaving most homes in the US not as secure), but I do think Black and Decker is made it worst by forcing then to copy Kwikset.

  5. Based on that finger light and the mylar tape, I’m starting to think Erroneous Designs has the same employer (at the same site) as me. ED, let me know if you see this.

  6. I have a praxis kit, is there anyplace to buy just the picks without buying the entire kit again if you break one? I have searched the internet, and not come up with the same picks individually.

  7. A trash lock transformed into a good challenge lock. Very nice use of scraps.
    And the upside down t-pins make me think they were going for a type of drunken spool driver… and it kinda worked. Now the mods to the core.
    I am a bit puzzled, why wallow out the chambers like that. But again I think I see what ED was going for though. I think that is. LMAO.

    Amazing goodies given away for sure.
    Thanks to all who donated and to the Webmaster who draws the names, the (Unsung heros)!!
    Thanks to you as well Bill without you the unsung hero would be out of an amazing job. Lol
