[@Murgoh]

I've seen something like this on the door locks of Renault brand delivery trucks we have at work. With the wrong key the core just rotates without engaging the locking mechanism, though those ones have a definite detent at the center position and if I recall correctly you can only insert or remove the key in that position. I took one apart a couple of years ago and figured it out but I don't remember the exact structure anymore. But it was basically a wafer lock with an extra sleeve around the actual core just like this one.

[@penfold7800]

Hmm. That's interesting

[@JPBennett]

The only tension you could apply is lining the sidebars up, and getting the little bit of tension from the two springs through the side ball bearings. I don't think that would be enough to get those wafers to set, but you might feel it just a bit. Trying to pick this would be almost like cracking a safe combination.

[@donjon999]

Yes, I think this is the only way to apply some tension to the wafers, but then the problem is to leave the sliders set after you find the gate. Maybe (if the sliders are magnetic) you can try placing a strong magnet opposite to the brass thing that hold the springs, to see if you can prevent the spring of the wafers to move them back after you, hopefully, set it to the gate.

[@1FatLittleMonkey]

Gangsheng sells the overall lock, but the engineering on the core is so different from the lock-body that it's doubtful they build their own cores. Therefore name recognition isn't useful here. Every single other lock they make could make Masterlock look secure.

[@ИванСнежков-з9й]

Edit: I missed a detail. The outer sidebar locks the middle cylinder and the casing, preventing it from rotating freely. The flaw bellow cannot be exploited. --- This specific model have serious design flaw, that makes it possible to bypass the lock. Basically, you need a tool that resembles the key, but longer and you don't need any cuts for the sliders. You insert it into the lock, press it inward as hard as you can and rotate. You use friction to directly rotate the middle cylinder. The inner cylinder (that has all the sliders) is open on both sides, so the tool/key can pass through it fully. To increase security, you need something to close the inner cylinder on one side. The insert tool may also have small spikes, with the idea of making small holes on the middle cylinder and use them as leverage for the rotation. It would leave marks, but they won't be visible without disassembly. I've read some comments about using a drill, and my first idea was to spin the inner cylinder fast and use the friction between the inner and middle cylinders. Or rotating and pressing the inner cylinder into the middle one, sideways or in depth. Then I watched the video again and spotted that the keyway of the inner cylinder is open on both sides.

[@roysammons2445]

Toughen up the lock and use a hardened pin on the side and you have an awesome lock. What's amazing is this came out of China, we are so used to locks that are poorly made. Looks like the main flaw with this lock is the brass pin holding the core in.

[@caseydarrah]

China can make excellent things, *when they choose to and are paid to*. They can make absolute junk, and have a habit of substituting materials- I've seen 4140L steel subbed in for 1050 (which is not an acceptable substitute). However, if you specify what you want and pay for it, they can do very well. I've seen Chinese fakes of Rolexes that would fool all but the most aware collector, but I've also seen ones that wouldn't fool anyone.

[@wtechboy18]

that's actually brilliant. They've basically just added three moving parts to a regular lock and made something that's nigh-unpickable. Now if we could get that as a modular core to put into some real good lock bodies...

[@Taluvian]

If the side bars are aligned, isn't the lock tensioning itself? Could you feel each wafer for the side bar catching on the gate? Number of wafers I think could make this nearly impossible. You would also need a tool to keep a wafer in place after finding the gate.

[@LaserFur]

just like a combination lock you would only get a feel on the highest two. So it would be a lot of back and forth with the specialized tool.

[@curlyvideos]

Yes, this seems to be the best approach imo. Decode it by feeling/listening for when the slider stops making contact with the sidebar, and decoding the lock. You could use 12 special picks.

[@WorBlux]

@@curlyvideos Given the same springs arcross sliders and same spacing when they are aligned, that's the weakness. If you can find one gate and measure the spring tension on the slider there, you can measure that on the other sliders and decode the lock.

[@samheasmanwhite]

It would need a very intricate tool, basically a key that you can add bitting to like lego blocks, while still being open enough to let you pick freely enough to feel the indent. It would be a feat of engineering as much as a feat of picking.

[@matthewrossilini5808]

Awesome lock. That's how you beat picking. Remove the ability to tension

[@jutonium2169]

Bill could you check if it would be possible to slide a shim between the outer housing and the sleeve? It looks like there is some kind of lip or a bend so I doubt it. Very interesting design! I guess it would be hard to drill out the core because it will just rotate with the drill.

[@nanaki-seto]

Na you would only need to stop the core from spinning. That would be trivial

[@yetanotherstronk]

The sliders look like SS, so I don't know that drilling the centre would actually help, even if you could keep it still. If you are going to drill, why not do what Bill did and drill out the core retention pin? If they change that to SS, then I guess a slide hammer is your best bet to avoid a very messy drilling experience. Or angle grinder, since we're going destructive anyway...

[@jutonium2169]

@@yetanotherstronk I agree with you. This is more a what-if-thought: "Wouldn't it be great to have that locking mechanism on your door?" Not as a padlock but as a mortise or other style of door cylinder. You are probably right about pulling the core with a Wendt Zieh-Fix or slide hammer.

[@penfold7800]

You could drill out the core down through the sheer line, but it depends if the sidebars are hardened. It might be easier to pull the core out because it's only held in by a flimsy circlip. Drilling out the retaining pin would be the easiest way though. Just like bill did.

Good morning Bill new to watching and new to picking learning alot for you thanks

[@mrdiggie3321]

If you put a strong permanent magnet across the lock body and rotate the core so the locking bar is on the opposite side, does it attract it enough that you have a reasonable chance of setting the first or last few wafers on either end of the core to allow the magnet to pull the bar in at one end? If you could do that you'd have some feel on the remainder of the wafers as you moved through them in order.

[@niklasnorberg6106]

If so they should make all the parts stainless and non magnetic

Is the gate in the same place on each wafer, and the inside tooth cut in a different place? Or are the gates cut in different places on each wafer? If the wafers just need to all be centered, it would be possible to build a pair of 6-toothed picks that could bypass the teeth that interact with the key.

[@graealex]

The most secure method still seems to be the screw from the top, blocked by the shackle when it is locked. That way when you're able to reach the screw, you already had to open the shackle some other way.

[@dmscheidtify]

Bolt cutters on the shackle are faster than drilling out a brass pin.

[@lowellforbes3208]

Reallly cool lock. I’d like to try my hand at putting it back together

[@ick5353]

The only "flaw" in the design that I can imagine exploiting is the fact that the wafers become "centered" for this lock to open. How about using some sort of tweezers or forceps that apply parallel force and then try to do a raking/zipping motion with them, while at the same time applying a twist for tension. The use of two picking faces working in opposition/conjunction would eliminated the need for a separate tensioner.

[@CristiNeagu]

You can't apply a twist for tension because there is no tension. Not only do all the gates need to be aligned, but the inner core has to be aligned with the middle core too.

[@curlyvideos]

Interesting idea, but it would only work if the sidebar spring is very strong and the slider springs are very weak. The inner sidebar has to drop into the groove faster than the 12 sliders come unaligned. Simply getting all their gates to align at the exact same second as they're all springing shut would probably be harder than just decoding the lock.

[@lemmonsinmyeyes]

Or a ‘blanked’ key with a bunch of little leaf springs on it for each wafer. Insert key and each wafer will find its own tension

[@CristiNeagu]

@@lemmonsinmyeyes Will find its own tension against what?

[@samheasmanwhite]

@@CristiNeagu Yeah, this is a lock where you would need to "feel" each slider and hope that you can discern some slight resistance as a gate passes the sidebar with the tiny force that is on it. And then it gets even worse because you have to somehow keep that slider in position as you tackle the others. This lock would require an intricate custom picking key that you would place bitting into as you pick each slider. Not impossible but also not practical, and adding any amount of false gates would make that method take exponentially longer.

[@RevMikeBlack]

Great video... and a very interesting lock.

[@LabRatJason]

Bill, pick it with superglue... lol. But seriously, if you have a very small needle: can you bend it 90 degrees, insert it half way and try to bypass though the side bars? If you can get it up into the area where the outer side bar is it will not only tension it, but fully bypass it.

Yep, or why not a full blown superglue or loctite attack and simply glue the inner chamber and containing sleeve together

[@loganlachance1890]

That is amazing. What happens if you try to tension from the shackle?

[@yetanotherstronk]

You can see from the little scratches/dents on the actuator on the end of the outer sleeve that pulling the shackle just pushes the ball bearings directly into the side of that brass actuator without exerting a turning force on the cylinder.

[@jdrissel]

Are either of the sidebars or the ball bearings magnetic? If so you could use a very powerful magnet to apply force to the sidebar without using tension at all. Then once you pick it, you would have to keep the sliders in place until you got the second sidebar down and rotated the cam a little.

[@JoelBergmark]

Awesome Chinese padlock!

[@Jester-Riddle]

... well, the lock itself is amazing ... the Padlock itself, maybe not so much ...

[@thelockpickinglebowski633]

Picking the first 2 or last 2 is not enough to gain tension. I have a cam lock version of this with a different shape keyway. The key must be inserted all the way until the final slider engages in order for it to turn the core. (Just FYI: the keyway is standard slider lock flat bar shape.) It's my favorite cam lock out of my entire collection of cam locks. Interesting note: i found it on EBay around 6 years ago using a one-word search term 'unpickable" and I've been unable to source another one like it anywhere ever since.

[@LostTheGame6]

So if I'm getting this right, there is a first sidebar interacting with the sliders, that in the locked position is flush, and recessed in the unlocked position. When it becomes unlocked and recessed, the second sidebar can catch the groove and rotate the actuator. Wouldn't it be possible to get feedback without any tension then ? If you line up the two sidebars, the springs are pushing against both, and so against the sliders. So, they are being tensioned by the sidebar spring itself. Granted weak springs would imply very weak feedback, but that should work ?

[@delta3244]

Weak feedback on sliders, from my understanding, is either exceptionally difficult or impossible to work with. But yes, the lock seems to tension itself. Perhaps adding some tool that applies outwards rather than rotational force would be enough to get sufficient feedback.

[@danareed1656]

[@redbugg99]

Heat treated harden steel ... this is the perfect clinker beyond high security. This cylinder can definitely be miniaturized to fit in a standard lever lock .. I hope this people are paying attention to this video.

[@b1tf1ghter]

the springs pushing the ball bearings on to the outer side bar are already tensioning the lock, as the outer side bar pushes on the inner one, when the core is aligned correctly. It is probably not a lot of tension delivered by these tiny springs, but its all you get ;) But I still think, that is not single pin pick-able, as the sliders have that V-groove and springs themselves, that will probably overpower those two tiny springs. but maybe you can decode it slider by slider (one should bind very lightly) and fix them in place once decoded...

[@14768]

Bill, I could see 2 potential exploits here. For one, if you could manipulate a single slider to the center with the core in the right spot, you could create a binding situation. It would take some time to find the correct slider which is the first binder. Then once it is bound you should be able to pick it. Second, it appears from the video that the sliders are accessible from the left and right sides of the keyway through the milled pockets, that they are all identically shaped, and they all need to be in the dead center. Could you grind some bumps on a wiper insert with the same spacing as the milled out pockets of the center core, and insert them on the left and right sides and push them out at the same time to center all of the sliders. I'm curious where can I get one of these locks, I would like to try these 2 methods. Or if you could get this lock back together and you can get me some dimensions I could try to 3d print a tool that would do this.

[@theparajaim8428]

clever ideas...props

[@yetanotherstronk]

The first idea other comments have pointed out probably wouldn't work as the slider springs are likely to overpower the springs tensioning the outer sidebar. The second idea seems more likely to work though. The tools would be a bit like comb picks. One facing outward on each side of the keyway, jiggle them a bit to pick up the correct set of sliders and push both outwards at the same time to centrally align all the sliders. Manufacturer could presumably defeat by redesigning the sliders with variations on where the gate is positioned on the outside.

[@14768]

@@yetanotherstronk True. I'm not sure how much they could vary it though, those sides are fairly thin already. The best thing for them to do would be to mill the core in a way that they don't have to expose the sides, but that might be basically impossible with a milling machine.

[@curlyvideos]

First, manipulating a single slider into the right spot for the sidebar to align with the groove wouldn't create a binding situation because the other 11 sliders would prevent it from dropping. Second, the sliders aren't identically shaped. The gates are in different positions, which is why the key isn't a straight line. Please post any additional ideas! We can think of a way to pick this!

[@14768]

​@@curlyvideos You 100% did not read what I said. The SIDES of the sliders are identical. Watch the video again, the left and right sides are identical, and they are also accessible through the milled groves in the side of the cylinder. Ignore the top sliders, that's not what I am talking about. And I do believe my first option would create a binding situation. That's literally the ENTIRE premise of lock picking is that minute differences in manufacturing tolerances create a situation where one thing will give or slide, while another will bind or rub. You would just have to find the correct slider to be the first binder. It would be an absolute nightmare to do, the second option is far more feasible.

[@richardkirka5977]

My theory is that these are "bets test" versions of an ultra-secure future lock. These are passed around to talented pickers for an assault on the core, and don't need all the ordinary hardening tricks for this phase. Imagine the frustration if there was an impressive level of hardening before anyone even got to the core. They'd all go into "naughty buckets" before anyone even started in on the hard parts. They don't need all the world's best pickers depressed and suicidal. Impressive craftsmanship on the core, which must have been costly to make, especially with consistent quality. The next step would be coming up with a faster/cheaper production method that wouldn't significantly degrade security. THEN the upgrades to the body and shackle would just be the frosting on the egg roll.

...gonna say it, impressed but... as soon as I saw the core spinning I knew there was an intermediate sleeve of some kind. I'm pretty sure that came from hard core puzzle sport which is where I've seen it used before. I can see lock picks being powered by drills, and the picks being pretty much carbide drill bits.

If you're going destructive, a pair of wrenches would be enough :-)

So you can probably (maybe) pick this the opposite way you pick a normal slider lock. If you put a tension tool in it and sweep it past the position where the first side bar engages with the second side bar, you'll *start* getting resistance when you have a slider in a gate. It might take a special tool, but I'm guessing if you just used a double rake that mimics the general bitting of the key, you should be able to feel for more and more tension as you get closer to setting each gate. Eventually the lock should bind up when the inner side bar is in enough to lock with both the core and the middle sleeve. It seems doable. lockpickworld has a rake/pick tool set for VAG car locks. Something like that, only with rakes on both sides instead of just one.

the end hurt my heart

[@DavidFMayerPhD]

FINALLY, a lock that even the great Bosnianbill cannot pick open. Where can I buy it?

[@The_Hanter]

That's really amazing core design but that pin holding the core you just drilled out is a huge weakness

[@PanduPoluan]

Imagine if this core is put in the Abus Rock 83/80 body ... see LPL's [567] : kzbin.info/www/bejne/gobQm3-CjdFrj5Y

[@Gollywog]

It's not just anti pick, it's anti drill - which is a better feature against the average criminal. Most criminals will usually use a drill to dismantle the core

[@anthonym2499]

if you prevent it from spinning, and stick a flag pick in it to maneuver the wafers - will the side bar spring provide enough push to 'set' a wafer? or does the spring tension of the wafer prevent it from 'setting' ?

[@BrooksMoses]

It looks to me like the spring that pushes the pair of wafers apart is as strong as the spring that is pushing on the side bar, and since the wafer notches are V-shaped they can easily just push the sidebar back out. Especially since for the first aligned wafer the side bar will only drop a tiny bit anyway, and those V-shaped notches are rounded on the corners.

[@BrooksMoses]

Actually, on second thought, there's a solid piece of evidence that that won't work. When you pull the key out, the spring tension of the wafers is what "unsets" the lock -- unlike a normal lock, you didn't "de-tension" it by pulling the key out.

[@phorzer32]

Wow, I wanna have this Lock to secure anything! Is this Lock LPL approved?

[@BD90..]

So unpickable at the moment. Did you try to tension the sidebar with a shim down the gap between the inner core and outer core?

[@PomlacAvdu]

So, certified unpickable? Way simpler and more elegant than the unlockable design in my head.

[@RyanRapetti]

I wonder if a sufficiently powerful magnet could apply tension to the secondary sidebar and allow picking that way. You'd just have to rotate it to the right position before you started picking. Without false gates, if you can tension the sidebar, it should pick relatively easily.

[@AlexanderBurgers]

Oh I see what went wrong. The impenetrable warranty sticker was supposed to be over the brass pin. Ah well. Very neat lock, and yes, I found it on Ali for like $12.
