 Hey, this is Alex in the continuing saga of the commando lock. I have a few more discoveries Which I made while I was fiddling with the pieces after shooting the previous video and waiting for it to edit and upload This is the these are the internals of the lock that the what came out of this poor guy So this is the locking cam. These are the ball bearings Chackle lock. Okay, no big deal And so the way that this operates is that the key You have the key in the lock Except I have this upside down But when the key would rotate there we go this way like that Then the ball bearings can fall in these little grooves and the lock can open and all that good stuff, right? We're all familiar with that now Back to the point. So We found this extra little part in here. So Let's talk about this part This part is the is the bit that is responsible for holding the shackle in really it keeps the ball bearings in place Ball bearings keep the shackle in place. This thing fails doesn't matter how good this cylinder is So let's talk about that This is made out of metal that I would call well soft This is a tension wrench. It's already got some scratches in it for my previous experiments, but I'm going to just make two Start and this is not sharp and this is just however south or it's sent it to me, right? I'm just gonna make two marks there okay, and You can see right where the Right at 12 o'clock. That's where I just marked it Okay, it scratches really easily with just a piece of Just a piece of wiper blade, which is not a particularly hard Not a particularly hard metal as far as I'm concerned Definitely not as hard as these ball bearings, which nothing except for my My carbide thing would cut. So these are in fact pretty hard steel But we'll get to those in a minute now back to this so this Puzzled me that this would be you know soft steel given that it's how critical it is in the locking mechanism And so it occurred to me that if this is easy to is easy to defeat Well, then that means I can probably drill out the lock well That's got to be really hard right because we already discussed all the great properties of this metal. Well In fact, it's not that hard There's a hole drilled in the same lock It's a 5 16th hole just about just about right to to punch right through this little guy and certainly enough to clear these ball bearings and Now you may say ah well You must use some special tool. I did I used my used my DeWalt 18 volt power drill and this cobalt Drill bit who cobalt Well, it is very exotic. They they only carry it in One aisle at each of the local hardware stores, and I think to buy one of them. It's perhaps six dollars So big investment You know a lot more expensive than bolt cutters Not really But that in about three minutes. I timed it cut right through there I didn't I didn't cut through the cam because I Wanted to show it to you so There's the cam So I would call this a vulnerability guys So if commando if you're watching I would consider making this out of a better metal Maybe invest in the same or similar kind of metal you use to make your ball bearings Speaking of the ball bearings where did my scribe go there it is now the ball bearings according to the literature are made out of quote 420 hardened stainless steel There it is right here in black and white Focus 420 hardened stainless steel ball bearings now The last time I looked at stainless steel It did not attract magnets And I'm trying to find something here that is stainless steel And Not succeeding But anyhow did not attract magnets now. This is a very strong magnet, but this is Clearly magnetic now. Maybe I don't I could be wrong Maybe these are in fact stainless steel They are hardened the only thing that would cut them that I had was this this carbide tip on this thing But I just have to question whether that's really stainless steel or not I guess I could both put in some salt water and find out this little guy Might be steel He did there's some iron in there somewhere because it kind of attracts the magnet, but not very strongly So maybe this is the 420 stainless and this is just carbon steel, which is nothing wrong with that But could just be an error in there. Anyhow those are ball bearings. That's vulnerability one That's the security vulnerability But the other thing I did while I was watching while I was waiting for the video to render the previous videos I was looking at there some other some of commandos actual videos and I noticed that they had a line of padlocks which I don't have which I did not buy one of Where you can actually take the shackle out and they have all sorts of different shackles that you can put on their different Kinds different lengths. They have long one short ones fat one skinny ones, whatever And this other line of padlocks that I can't remember what they're called, but They cost a dollar or two more. I think and you can remove the shackles. That's pretty cool. Well when I was looking at this Cam I thought to myself why do they have this enormous hole on the side of the cam zooming back in Why do they have this enormous hole on the side of the cam and then I saw the video and I was like, huh Maybe my locks can do that too so I Reverse picked one of them and in fact if I turned the cylinder the if you turn it Counterclockwise 90 degrees with the lock open sure enough. I picked it open and the and the Jackal fell out. So I said to myself. Well, that's kind of neat I bet I can make a key that will do that by taking a hint from Sergeant and Greenleaf on their control keys and unlike the Those big military padlocks and just cut some notches in the key So that's what I did. I actually filmed this but it took forever Because it I'm always very slow with that Weakens the key a little bit, but if we put the key in Open the lock Rotate the shackle to there Bring the key back and rotate it to there. Aha Shackle comes out Pretty cool. Put another shackle in if that's the shackle you use to do your your penetration testing put the put the shackle in return this to the Unlocked position put that back in Pull your key out and you're done and then of course you can just give the regular key to your Your friends and they can only open the lock, but they can't remove the shackle because the Thing is in the way now the other way you could affect this change is simply to remove These two metal tabs here Which kind of look like drill protection, but they're not they have no real structural value based on our previous testing so you could just file those off or cut them off and You'd have a removable shackle lock So I thought that was pretty interesting So maybe that's just a little bonus for those of us who are geeks and take our locks apart And if you're willing to do that then you find out that you have a removable shackle version of the same lock I suspect it's probably More likely that they only wanted to make one type of this little cam Which is reasonable and so they made the same one and they just put the little wings there to keep you from Doing that with a normal lock At any rate guys commando this this cam So it's costing you security on your products, and it's Possibly costing you money if people you know realize how simple with the simple differences Between your your products, so I would suggest enhancing this part. I can't cost that much To make this out of something better and maybe to have two different kinds that you use depending on the lock So there you go, and I think that is everything I have to say and that everything I know about commando locks at this point in time Despite all of the things in this video. I still like them. I like them in the US. I like the cylinders They're fun to pick and I can tell that they're they're trying to do a good job they're they're trying to do quality and You know looking forward to seeing what they have neck have in the next model line, so any rate Thanks for watching. This is Alex have fun, and please keep it legal Cheers
