Okay, you too. This is Alex. I have one of these master lock things on my front door at the moment. It doesn't have a key in it, but the realtor wanted to use it to leave keys for some inspector or something that was going to be looking at my house. It wasn't a big fan of it given who it's made by. But it wasn't mine, so I didn't metal with it. What I did do is I ball one to see how easy it would be to decode or bypass. And I'll show you. It's pretty much the same technique that you may have seen on other of these types of locks, where you use a little feeler to sort of read the little notch on the side of the wheel, which of course is much harder on camera than when you're just doing it in your living room. That's definitely one there. Like seven. The newer ones that they use in this area are made by a company called Supra. They made other much crappier ones back in the day, but these are electronic. And I'm pretty sure I can work out a way to bypass them, but it would be pretty tricky. And they seem to be made reasonably well. I don't know about how secure the software is, but I'm not a crypto geek. So, there's people online for that. What I'm attempting to do is feel for the little edge of the thing, which I got a very positive lock on on the other one. Okay, that's my line method. So, I've got 9.572. Let me just double check all of these. That's more like a seven. You can sort of see the little thing rock up, because it's sitting down in the notch, and then when I roll the wheel back. Okay, so I know it's not 9.772, but it's going to be something relative to this. So, I'm pretty sure it's not one click off, so I'm just going to start with two clicks on each wheel. Okay, that's not it. There we are. And that's it. First time I did this particular lock, it took me a little longer than that, largely because I had to figure out the tool to get in there. I just had a little better, oddly, and a little better tellances than that Brink's that Bill did the other day. The tool I've got is a piece of stainless steel, 5,000ths of an inch, feeler gauge, or shimstock that I've cut. And he's the grinder to sort of shape down, and then very slightly tapered or beveled the end, just very to sort of tap it up against the grinder, and then polished it a little bit. So it would slide in there better. So here's the box, zooming out again. And I haven't taken it apart yet, but... Okay, so this doesn't want to come apart. I think there's two more screws on the bottom here than, and this thing is pinned in, so it's not going to come apart. But I can tell you about two other actually good design features on this. One is the shackle. The shackle is run by this little, is released by this little lever here. You pull that up, and then you can lock it onto something. And it works by, there's a bar with two little notches, and when it slides this way, the notches move out of the way of that thing, and you can go in and you close it at that thing returns. So in order for the bolt to open, that little lever has to move this way. There's no other way for it to go. Okay, turns out, and I can just show you this, if it's open, and this lever is back, because it can't return, because the notch is there, or the notches hitting the shackle. You can't close this, and it's because part of the body of the lock here runs into this little guy. The corollary is that if this is locked, and this is closed, there's no way that you're going to be able to shim that open, or stick something in there, and manipulate that lever open. So that's kind of a nice design, something you'd have some kind of thoughtfully don't see very often. And then the other thing is the reset feature, and this reset's just like most of these things where when you have the combination dialed in, you pull that up, and then you can twitle with the dials. And on so many of these things, it's this little bar that mid-side to side. I did a really bad job of getting that on frame, but so it's this little thing here, push that in. But this little pin comes out, and if you notice that pin runs into the side of the case when, or the body, when it's extended, and when the thing is closed, it would sit against the inside of the door here. So two things, you can't close it with the reset button engaged, probably a good thing. And the second thing is that if it is closed, you can't somehow manipulate that release button into position, because that little pin has to come out and hit the, and move, and it would hit the body. The other thing is if you're done, don't have just the right angle, and this doesn't want to open. So the physical design of this is reasonably secure. It's all metal, I don't know what kind, but, you know, probably I would hope it's steel. Let's see, shackle steel. The body is, I don't know, some of the parts are steel, some are not. This might be steel, it might be aluminum. But, you know, it's made out of metal, and, you know, decent construction, you'd have to bash on it a lot to get it open. But, the primary locking mechanism, this combination lock is vulnerable to this standard decoding technique, which, I don't know, to me, I don't really want this on my house. It's no better than that Brinks that the bill was working with. And unlike the Brinks, this ends up stuck on your front door, hanging off your door handle. So everyone in the neighborhood walking by can see that you have the key to your house in a crappy padlock, hanging on your front door, just waiting for someone to get in. So, and the last thing is that my realtor uses the same combination for pretty much all of her locks, and it's pretty predictable. This is not yet, because this is my lock, but, so there's not even good sort of key control. So, if your house is on the market, and they want to put a box on your house, have them get something a little better, at least one of the dial combination locks that are a little harder to manipulate, or one of the electronic ones that requires some encryption. At least the person that needs to be a log geekier to defeat it, or use a whole lot more force. So, anyhow, master lock, key box, decoded, opened, and raped, I guess, in discussion. So, this is Alex. Have fun. Keep it legal, and remember, only pick your own locks, or locks you have permission to pick. Cheers. Thanks for watching.
