The Most Weather Resistant Padlock Ever Made — S&G Environmental

This is the Lock Picking Lawyer and what I have for you today is probably the most weather resistant padlock ever made it’s the railroad version of the sergeant and Greenleaf environmental padlock, and it was sent to me without a key by Chris in Florida. This is a really beefy lock that you can leave out in the rain and snow and dust sand, ice, salty Marine conditions for years or even decades, and you can depend on it to work. So you can see why this might be attractive to a railroad, to lock a seldom used gate or switch or storage shed. Unfortunately, that’s where the good news ends, because, despite this heavy build, it’s not very secure now Chris asked me to do two things. First, he wanted me to pick it and then disassemble it, so we could see what’s inside.

Sadly, I’m going to have to disappoint him on both counts. As for disassembly, the only way to do so is drill a pin out to allow this top plate to be removed and as for picking while it certainly can be picked, no one who knows this lock would ever do so. You see this is a disc detainer mechanism with only three discs and each disc only has three possible combinations. That means there are only 27 potential keys of those 27. Only about 10 or 12 were actually used and, as you might expect, I have either an original or homemade version of each one.

This is an example of a homemade version, and this is a factory key. So despite Chris not sending a key, it took me about 20 seconds to figure out that the 102 key was the one that opened this lock. So Chris, that’s how someone who knows this lock would open it up. Looking at this homemade key, you can see just how easy it was for me to hand file this out of brass Rod stock though it just so happens. I have an extra original 102k, so that will join this lock in my collection now.

The real question here is why railroads would use such an insecure system on critical infrastructure. I mean sergeant and Greenleaf does have a higher security version of this very lock. So on that question, your guess is as good as mine. In any case, that’s all I have for you today if you do have any questions or comments about this, please put them below if you like this video and would like to see more like it please subscribe and as always have a nice day. Thank you.
