It's a lot that allows the user to both re key the lock and change the bidding on the key to match it.

It was the product of an Indiegogo campaign a few years ago, and I'm not sure if he's air still made, but because the mechanism is so unusual, we're going to do things a little bit different today.

I'm going to take it apart first to show you what's inside, and I think that will help.

You better understand what's going on while I'm picking.

Taking it apart is very easy.

When the keys in the unlocked position, we can stick anything sharp down this little hole that pushes a D tent that releases the core.

Now, if we look at the core and the K, we can see each one has four rotors, and each of those rotors has six numbers on it.

When the rotors air set so that the numbers on the core match the numbers on the key, they will work together.

In this case it is 1431 nowthe lock rotors are particularly interesting.

Each one of them is a stand alone lost court with three pins actually arranged.

So when all four of these rotors are bound together, they essentially create a 12 pin lock.

Now, a word about the key space that is the total number of possible keys.

With four rotors and six positions, there are about 1300 possible combinations.

That may seem like a lot until you realize you can look down the key way and in a couple of moments, narrow it down considerably.

If there is a pin at the 12 o'clock position, we know that rotor set on an odd number.

If there is not a pin there, we know it's set on an even number.

That may not seem like a huge advantage until you do the maths and realize it narrows it down from 1300 possible combinations to just 81.

That's few enough that you could probably try them all if you had some time and one of these user configurable keys.

Okay, let's put all this back together and see what it takes to pick it open.

Okay, that is locked up.

Tensioning is done from that little notch there, and I just bent a piece of music wire to reach in and grab onto it.

It's fairly easy because we have such a wide open key way.

I'm using this thick 50 thousands pick and that Make sure I don't slide off the sides now as far as strategy goes, because there is some take up between each of the rotors.

This picks a lot more like 43 pin locks than it does 1 12 pin lock.

So I'm gonna work.

May my way back, setting each of the three pins on each of the rotors.

That's writer one number one, too, of three is binding tightly.

Gotta click there.

Felt some movement.

Number two one two three felt some movement.

I think two is set going back to the 3rd 1 two three.

I think we have the third Roeder set and fourth rotor one two for his binding very tightly, and we got this open so not too hard to pick.

It really is an interesting concept, but between decoding attacks and picking, I think it could definitely use some improvement.

In any case, that's all I have for you today.
