Barrier 2


And that is Barrier 2M


Lock "cylinder"


There are three groups of pin chanels. Each group has three pin chanels.


Each chanel has spring, two pins and ball bearing.

That looks very solid! The cylinder mechanism reminds me of the Polish Gerda locks. Is your lock pickable? Has anyone made a tool or pick for it?

Thank you for sharing so many nice photos, including the lock installed!

Yes,Gerda and Barrier is similar lock. But Barrier has many differences from Gerda.

As I know, today has not method to unlock Barrier (2M and higher) with picks.

Does the hole in the key above the two bitting cuts have anything to do with how the cylinder is driven (turned)?

I think you mean the hole in the A-position? This hole is zero(lowest) depth key cut. B is first depth, C -second. No cut-4th depth

[kerti]

how the cylinder is driven (turned)?

The key engages with cylinder with rectangular cut to turn cylinder clockwise or contrclockwise.

And this is one from a few differences between Gerda and Barrier.

N.B. The keys at that pictures are for Barrier 4! That is why these keys have other key cut structure.

Copying Barrier key

[GWiens2001]

Ahh, thank you, Kerti. My son has a key (but no lock) for a steering wheel lock that uses that drive principle. Think using some thin wire, you could make a tension wrench that would fit the metal tab and get that lock open. Thinking of getting a Gerda to try the theory.

Pin chanel inside



Ball bearing also makes problem for picking and blocks possibility of bumping. I think the decoding will work for that lock only. John Falle style instrument.

[GWiens2001]

Would probably try making a pick shaped like a letter F on the end. Place the two flags on either side of the ball bearing and lift it.

May be. Needs not usual torque key. Needs special picks. This is cylinder lock, but not usual. Big 3D cylinder lock

Barrier 4








Bolt removed

Side view


Barrier 4 has new key cutting system. Pin chanels have random position into cylinder space.(may be manufacturer lie )

Interesting stuff!

Do you think there would be enough space to use a dimple pick next to a square rod-tension wrench?
