However, after taking a close look, I found a design flaw that allows it to be opened in moments with a very low skill attack.

So what we have here is a pretty normal looking, 50 millimeter, brass bodied padlock.

It has an eight millimeter hardened steel shackle, and it does have spring loaded locking lugs inside, so this theoretically could be shamed open.

However, the tolerances around the shackle are so tight that I was unable to get shims in both sides.

They did a fairly good job with pick resistance as well.

In fact, let's look at that.

First, let's see what it takes to pick this open, going to put some bottom of the key way tension in here with a fairly narrow wiper insert to give me lots of room for my pick.

And I'm going to be using a standard hook in 25 thousands.

Okay, Number one is binding.

Click out of that and a little bit of a false set.

Little counter rotation on two counter rotation on three.

Got him set.

But we lost our false set, Looking at one and two and looks like we dropped one.

So 12 three are all set.

Let's go back to four little counter rotation there.

I got four set, but once again, we lost our false set.

C one, too.

A number of three.

Looks like we dropped him.

And number one, we dropped one as well.

Okay, let's see.

12 34 Okay, five is our last pin.

Little counter rotation there.

Okay, Number five.

I feel like I might have pushed him a little too far.

Maybe over.

Set him.

Okay?

We dropped our I think pin number one, we lost our false set.

No pin number two.

There we go.

Let's see.

34 five.

There we go.

One is binding again.

And we got this open, so it may not have looked like it, but the combination of spools and very tight tolerances makes this a pretty tricky locked open.

It does require some skill.

However, as I said before, there's a flaw that we can exploit to open this much, much faster.

I'll show you the problem on this model first.

Usually, when a lock is opened, the key and driver pin stack is raised to the point where the plug can turn due to the gap between the key and driver pen.

But imagine if you could lift both the key and the driver pin above that sheer line.

Now it's not possible on this model, and that's the case for most locks as well.

But sometimes a lock maker overlooks this and leaves enough room for that toe happen.

And that's the problem with this lock.

And there are tools specifically made to exploit this flaw.

They're called comb picks, and they push up on each of the pin stacks and lift them all the way above the sheer line.

Just that fast, we got it open, and I have one more of these locks here once again opened it very, very quickly.

So as you saw, this exploit is very fast, and it is a great example of how a small oversight and either design or manufacturing can translate into a major security flaw.

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