How do I pick this lock?

[Keyskeyskeys]

Got a couple of lock that I picked up in Asia that I can't open. I've dismantled one of them and the inside looks like this:




The red bar is one single bar, not five separate pins.

I'd imagine that it would look like this when the pin is set:


The problem is, if I applied any sort of torque, the red bar you see in the drawing gets stuck. If I don't apply any pressure, the spring that pushes the red bar
doesn't have enough force so that the bar would hold the blue pins up.

I've also tried turning the lock so that the red bar is pointing down, so that gravity and the weight of the red bar could help trap the blue pins but it's not working.

Any ideas? Thanks.

I haven't got even one single pin set yet. I think it's because of the red bar so I have to have all the blue pins in the right position at the same time for the lock to unlock.

Hi kkk,

you found an interesting lock. Do you mind to PM me how to get one?

It looks similar to mine but, as Fredmad pointed out in that thread, has a different mechanism.
Also, you may find this article interesting.

Please post a photo of your locks, we are all interested to learn more.

Thanks!

Does the lock seem to be extremely well manufactured? If so, the tolerances are likely very tight. Alternately, a slope on the sides of the pins with greater spring tension on the pins than the sidebar would do a lot for making it difficult to pick and I'm guessing that's where your problem is coming from if it's not a very well manufactured lock.

Out in the wild I'm betting this lock would be meeting the rotary pick or I'd be shining a light down the key way to try to visually decode it.

Can you feel the red bar slightly hook on the blue pins grooves when u push them up without any tension? Maybe if you can get the bar to be positioned correcly for just one pin and then apply tension, maybe then the second binding pin would bind abit more. But you will have too keep the first pin in place with ur pick and release tension so the red bar can release to bind on a blue pin. It probably wont work if the tollerances are very high. Very clever desighn though! Let us know when you have figured it out.

You find an interesting lock. Its better that you can send some images of your lock.
By these pictures I assumes that ,may be if you can get the bar to be positioned correctly for just one pin and then apply tension, maybe then the second binding pin would bind a bit more. But you will have too keep the first pin in place with ur pick and release tension so the red bar can release to bind on a blue pin.

Sorry for the late response, guys. Been busy working for the past couple of weeks. Anyway, here are some pictures of the lock. If you're seeing yellow frogs, then you might need to get an imageshack account.

As you might notice, the pins go all the way to the bottom so that means if the combination of 626 or even 646 (or anything with a deviation of two or more) appear in any of the combination, it's virtually impossible to pick it without a special tool, even without the side bar.

I think the lock is susceptible to brute force though, since you can get a lot of leverage from the W shaped design if you have the right tool but what's the fun in that?

Thanks for posting the pictures

I think that without the sidebar the lock will be free to rotate, without the need of setting any pin. The sidebar is the only thing that blocks the plug, if the pins aren't at the correct heights.

Seems like it works similar to the design of the Medeco cam locks, minus the rotating pins. Just key pins that interact with the sidebar. Very cool lock.
