It says Adam on it.

But it's now the Folger Adam company, which still makes these locks, and they are also still used in prisons.

You really need to see this, though next to a normal locked to fully appreciate how big both the cylinder and the key really is, they're both absolutely massive.

Now, before we get to picking, I want to talk about these keys and what is horribly wrong with them.

This lock actually did come from a prison, and though the Keys air knew the bidding in the lock is original, it's master keyed, as are most of these.

And a cardinal rule of Master King, particularly with restricted key blanks, is that the master key should always be physically larger than the operating key, at least in one or two positions.

That way, it's impossible to create a master key by filing down a normal kay.

Unfortunately, whoever set this prison up apparently never learned that lesson, because if we look at the operating key and the master kay, the master key is smaller than the operating key in every position.

But more concerning about this lock is the ease with which it can be picked open.

Let me show you just how fast it iss using this big fat Z bar.

Because I need something to fill that huge key way up.

And this wave rake.

Wow, that was pretty quick.

Let's do that one more time.

Once again, in very, very quickly.

Now, At first I thought I got in so easily because of bad bidding.

So what I did was I pulled out another identical lock.

I have this one came from a different prison and decided to try it on this one as well.

It's okay.

Uh, this one does not have a backer, so I'm gonna need to Let's pick this a different way keeping my finger over the front So this whole thing doesn't fall apart once again very, very quickly.

Now, I'm not going to go into how picks might be improvised in a prison setting for obvious reasons.

But suffice it to say it can be done, and this is an issue that really needs to be examined anywhere.

These locks are used.

Okay, let's take one of these things apart so I can show you what's inside.

Let's do this one.

It's a little bit newer and I can lock this up.

Since I do have the keys.

Let's start by taking those screws off the back.

And here we can see the cylinder and the master ring.

Let me show you why they have them.

If I insert the operating kay, you can see just that center cylinder turns.

And then if I insert the master cake, you can see that the cylinder and the master ring turns.

That's a way to master key locks That doesn't well, doesn't decrease security quite as much as normal.

Master King might.

Now, since I don't have a follower, the size I'm going to do is just slowly pull this cylinder out and hopefully I can manage to use the cylinder itself as the follower.

Okay, so we have This is slot five.

So one two three, and it's normal to find that many pins because of the Master Kane and that keepin doesn't want to fall out will come back to it later.

It's all standard pens and the last one Okay, that was really greasy inside this master ring should slide out after I get these springs.

One, two, three, four And the 5th 1 There we go.

Okay, let's see about getting these key pens out.

Now, I think maybe the best way might be to push them out with a lock pick, and each one of these is going to have a ball bearing behind it.

I just lost the ball bearing on slot one.

And the reason they have that is because these locks are used an awful lot and the key pins would wear down and the lock would stop working.

So by putting a hardened ball bearing there, you make it such that the lock does not wear out quite a CE fast.

You usually only find that on some higher end commercial locks.

But these air obviously built to last.

Not an awful lot to see in here.

Okay, we're on to pin four or chamber for and chamber five.

Okay, so not a whole lot to see in this lock.

It's unfortunate the level of security here.

However, there are options for replacing these locks with, for instance, ASA twin cores that would be much higher security and would be very, very difficult to pick with improvised tools in a prison setting.

And that's certainly what I think current users of these locks auto Look at.

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