 Okay, YouTube, 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. I wasn't a big fan of it, given who it's made by. But it wasn't mine, so I didn't meddle with it. What I did do is I bought 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 you're just doing it in your living room, but that's definitely one there. Seven 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 other people online for that. But what I'm attempting to do is feel for the little edge of the thing, which I got a very positive block on on the other one. And I think, okay, that's my alignment is off. So I've got 9, 5, 7, 2. Let me just double check all of these. More like a 7. You can sort of see the little thing rock up. It's sitting down in the notch. And then when I roll the wheel back, okay. So I know it's not 9, 7, 7, 2. 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. Haha. There we are. Oops. And that's it. Now, first time I did this particular lock, it took me, I don't know, a little longer than that, largely because I had to figure out a tool to get in there. I just had a little better oddly and a little better tellances than that Brinks that Bill did the other day. The tool I've got is a piece of stainless steel, 5,000 of an inch feeler gauge or shim stock that I've cut and used a grinder to sort of shape down and then very slightly tapered or beveled the end just to sort of tap it up against the grinder and then polish 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 then 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 notch is 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 don't even kind of thoughtfully don't see very often. And then the other thing is the reset feature and this resets just like most of these things where we have the combination dialed in you you pull that up and then you can twiddle with the dials. And on so many of these things it's this little bar that moves side to side. I did a really bad job of getting 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 it don't have just the right angle on this it doesn't open. So the physical design of this is reasonably secure. I mean it's all metal I don't know what kind but you know it's probably I would hope it's steel. Let's see shackles steel 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 the 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 if you will. 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 lot geekier to defeat it or use a whole lot more force so anyhow master lock keybox decoded opened and raped I guess and 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.
