I think the design of this lock is to prevent ghost keys, meaning, that if you master key a lock with 2 completely different bittings, you will have "intermediate" keys (which is a mix of the 2 different bittings) that will fit aswell. The use of multiple shear lines, allows 2 completely different bitted keys to fit a lock, while still disallowing a "intermediate" key to fit. And I can understand why this is a "pump lock". If a gas station wants to buy gas from different suppliers, they would need to have different locks, because each supplier don't want to carry a big keychain with one key for each gas station. But on the other hand, the solution with multiple locks arranged so a single lock opens the gate, like on certain gates, isn't as secure either. So basically, I think it works like this: You order the lock from one of your suppliers, which will give you a "gas station owner key" (which is a leaf key). The supplier retains the master key. Then you can "add" a supplier to this lock, which is encoded in the second shear line. This supplier's master key is then encoded in the second shear line. Now you have a lock that takes 2 master keys, and one leaf key. I think it might be possible to add even more keys to the lock, by replacing one of the spacers with a additional ring, and replacing the spring holder with another ring with a screwhole, creating 2 additional shear lines. And thats why the middle ring is always fixed with the screw, because a lock with 4 shear lines, with nothing holding the middle part fixed would get very sloppy. Then you can have 4 different suppliers serving your station. Howadays, you usually have electronic access control systems for this. Sometimes with a key box so the supplier scans their card, the box opens, and then it contains a key to the locks on the pump (or fill neck for the underground station).
Reminds me a lot of an Ace lock with warding added. FWIW, Pollux is a Latin word, adapted from the original Greek, Πολυδεύκης (Polydeukes). Pollux is the elder of the twins, Castor and Pollux, represented by the constellation Gemini. It's also the name of the brightest of Gemini's stars.
What a fascinating lock. I remenber watching you pick a pump lock or two before (🤔?) But this one is very cool. Yeah the others were just cool. 😂 Love your explanation and picking as always and you are a brave man taking that lock apart. 😉👍
Nice pick. I was thinking of using tape just as you pulled it out. I think some lock manufacturers are purposely designing locks for us not to disassemble.
This seems like a minor upgrade to a tubular lock. The machining for this probably means it is far more expensive than it should be for the utility and security it provides. Perhaps its odd construction will confuse potential intruders, but not for long.
Do you have any idea how expensive this lock was as a new? The manufacturing of this lock seems even more demanding than Abloy Protec and this is definitely easier to pick.
@Lock Noob I am a big fan of these companies who take the time to innovate and make the effort to improve their locks. Thanks for the video Lock Noob. If I tried to explore that myself, I'm sure it would have never gone back together the same. Better you than me. Hehe. Appreciate your work, mate. 👍 Ps. How did you go getting it back together after making this video? 😁
@@mathieuvillegas Tubular picking tool doesn't need different height stacks to work. It works by friction from the sides of the pins instead (and the friction is applied by tensioning the lock core). The dual shear line might be able to block this kind of tool but I'm not sure which is why I'm asking.
@@MikkoRantalainen anyway, tools exist for this kind of lock (Pollux 5, Pollux 7), but it doesn't work with the dual shear line version like this one or the Pollux 7000.
Okay I think it's the algorithm, let me see if I can get around it. There is something involving you, which I did as a gift, which I think you would enjoy. Follow the bread crumbs my friend.
Looks a very scary lock, well done!
Also great gutting.. so many parts.
Great Job all around ⭐️
Thank you!
Never mind the Pollux. Here comes the pins...😂
Lol
Amazing design. Perfect for drilling out. 🇺🇸
😂😂😂
É uma péssima imitação dos mecanismos fichet 😂

Interesting!
Here we are again talking Pollox 😉🤣🤣
Lol
This thing is a total trip.
It’s very cool though
Yes, brevetay is the pronunciation and it means patented. Cool lock too!

It was an absolute nightmare putting it back together
Very interesting lock design indeed! WOW! Have some pins! Braver man than I, dissembling that one lol
Nice pick. I was thinking of using tape just as you pulled it out. I think some lock manufacturers are purposely designing locks for us not to disassemble.
This was so hard to put back together
What a load of Pollox! xD
Lol

It’s very over engineered imo lol
a cool lock Ash mate great video 👍👊🇬🇧😎😊
Thanks Leon mate!
So much engineering went into this lock, you sure its french and not german? 😆
Def French
stuff like this is why I stick to pin tumbler pad locks. I won't run out of challenges anytime soon. Interesting design, though.
Very!
The multiple shearlines are similar in 17:57 Small Format Interchangeable Cores
Or the Corbin master ring locks
The coolest key I've ever seen
It’s so cool
Do you have any idea how expensive this lock was as a new? The manufacturing of this lock seems even more demanding than Abloy Protec and this is definitely easier to pick.
About 270 new
Double euro format
@@clefmentine That's insanely expensive!
8:20 is it particularly easy to impress while on the in-between position?
I guess so
7:00 I guess you could use plug spinner here to avoid picking it multiple times to open the lock, right?
Unless you can do 360° in ond go very fast it's not going to work

It took over an hour. Closer to 2 most likely
@@LockNoob What a pain. Thanks again mate, your efforts are very much appreciated. 👍
Is this vulnerable to typical tubular picking tool (the self-impressioning style) if you simply had suitable picking head for this lock shape?
Not at All. All stacks have the same length so you can't impression it and it has a dual shear line, so picking is way more difficult

Is it similar to a bramah style or Chicago
Similar

I saw the vid. Very funny thank you 😁
@@LockNoob Woohoo! It made it to the man. Thanks for watching Lock Noob, love your channel!
Which product is that?
Variations of a Bramah
In a way I guess
May I challenge you to a 14 lever Chubb Mersey/ NATO lock.
Hard to beat even with a portable x-ray scanner.@@LockNoob
