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. Awesome job +bosnianbill! Bi-Lock is going to have to change the claim on their website. Their website says:

    "There are claims of people picking a BiLock cylinder. In every case we have researched, the operating key was already in their hand and they refused to let us examine the actual lock. This leads us to believe that the locks were "modified" to make it look easy to pick. The locks manufactured by BiLock are to the highest standards and quality. We have yet to personally witness any original BiLock cylinder being picked open without a key. We donate our locks to picking contests around the world to maintain this confidence."

  2. made a tension wrench from stainless steel rod 1/16 to fit nice and snug with a bend for comfort. my prybar was stripping out my cores.

  3. An awesome achievement! A 12 pin, double sidebar bi-axial is really getting into the supplemental oxygen "death zone" scale of a mountainous challenge -( supplemental some-thing any way! ) If I got started on one of those – I would be worried I would look up, one day, from a deeply scarred, deformed key way and pile of broken picks – to realize life all but was over! :)

  4. "THERE WE GO BABY!!!! YES, OH YES" hahahaha, I'm enjoying your vids Bill, as a new-to-lockpicking man myself I thoroughly enjoyed, and agreed with, your excitement there lol keep it up :)

  5. This locks construction makes me wonder about the definition of "high security lock". Usually "High Security" means that there is a secondary locking mechanism, so the "picking and pin binding" is no longer a linear process, since secondary locking mechanism is supposed to work in parallel with normal pin tumbler action. For example in a medico lock the side bar and pin sheer line can both bind the pin and picker does not know which mechanism is the binding one. However in this lock, or for that matter Schlage primus or ASSA there is still only one way to bind each pin. Medicos with non-ARX pins have other security flaws, essentially breaking the "parallel action" of the sidebar; however the "Idea" behind ARX pinned medeco is the best one of the bunch; but execution of that idea is a fail.

  6. How would you rate the high security locks you have picked or couldn't pick. Bi Lock , Medeco, Assa, Multi Lock? Others I didn't list?

  7. Ah, I've always been very intrigued by these locks, as every school I've been to here in Australia has had them. Do you just not use very secure locks in the US or what? :P

  8. Hi Bill, I just watched this video and I'd be keen for you to dismantle the cylinder and show us the actual pins. There is a way to set up a BiLock cylinder so it can be picked but the proof is in seeing the pins.
    Cheers from Australia

  9. I work in Canberra, the capital, and bilocks are very common in government offices and other places. I have two keys for two different buildings, but either will open the padlock on the front gate.
    It's nice to know they aren't a simple pick :)

  10. Bilocks have side pins which he does not pick. These locks cannot be picked unless you screw around with the side pins. Rigged, Your full of shit.

  11. Thanks bill im gonna go an try this i have few different locks what am i actually feeling for is it the tension from the spring loaded pins in the lock sorry if its late were you are im in the uk !!!

  12. Hi bill im a new subscriber very interested in locksmithing as a hobby i can get picks etc from amazon just wondered what would be the best first lock to try an pick padlock or standard door lock?

  13. damn fine work Bill, looking forward to getting a couple of these to learn on.  This is not the (newer)model with the active element, but I'm sure it's just a matter of developing a technique for it.  I'll see if I can't get my hands on one for you.

  14. Can I please break your heart a little bit?
    I live in Australia and spent 5 years working, keying up and installing Bi-Lock locks to the Australian Defense Force.
    That lock that you have is many years behind, there is a type '2' Bi-Lock that has a '13th' Pin in the very front behind that little spigot that you have bent with your tension wrench.
    The key has a little pivoting pin that pushes up on that 13th pin when you insert the key.
    I will have to post you the newer model Bi-Lock to prove yourself and their 'anti-pick' claims.

  15. I remember working on a camping ground where the entire system was bi-locks. About 40 locks in total. My friend who was an activities manager lost his master key and it was going to cost NZ$36,000 to get the system replaced! 

  16. Great job on the pick of the BiLock. Six years ago they installed these in our new county facility on all doors and the power electricians have a bunch of padlocks with BiLock slugs in them for tagging out electrical contacts.

    BiLock key duplication process is very interesting how they first cut the blank then fold into a "U" shape still maintaining precise tolerances.

  17. Lol…ur funny…it's good to hear you celebrate when you get a hard lock open.  I feel the same way when it happens to me.  Good Job buddy. 

  18. There is a building in Minneapolis that runs this lock, my dad was issued some keys and the replacement fee per key was around 300 bucks……..Glad I deal with Best
