Ocariz Security Cylinder
I found on OLX (ebay's little son ) a cylinder for sale which I found interesting. Mainly because of the key. So here it is!
As you can see It's a regular pin tumbler but the key has dimples on both sides. Making a total of 15 pins!
So I had to gut it
First, Sorry for the flashy pics, I only noticed it when I opened them on the computer, but it's understandable:
The key with all pins aligned. The pins on the right and left are the ones that are operated by the dimples.
I found this pretty odd. And the cylinder had no springs nor driver pins for those, just a small "ramp":
Here's the plug BTW:
I found this system pretty strange, had never seen it before. So When I assembled the plug back I understood!
With a key, everything is aligned, as normal:
But... without key, instead of the side pins being pushed inside by the driver pins, like regular pins are, they are pushed outside by the key pins:
So they block the plug unless the key has dimples to let them go inside the plug, allowing it to rotate!
So although it has 15 pins, only 5 of them are active.
I haven't picked it yet, but I believe it's just a matter of picking a regular 5 pin tumbler. And I believe that the dimples on the key are just to confuse you, as it would need just holes, not encoded dimples. I will probably be making holes on those dimples and see if it interferes with anything.
I have also found that the lock has an anti-drill pin, and the 2 first pins on each row are also hardned, you can see that on the previous images:
Have you ever seen something like this?
For the price I think it's a pretty reasonable lock.
