Need Help - How to reassemble a 140 aka How do I rekey a 140 on purpose?

@thenetnetofthenet Hee Hee Hee... Not seen one pulled apart like thatšŸ˜†

Usually that last pin (6) is held in solid without a spring. They are or use to be assembled via the top pin side through holes in the lock body. Tiny brass caps are forced into the holes and then they are sanded flat to the body. Hard to see the caps at that point. Check out LockpickingDev's video here for what the side looks like with the caps removed.

haha! I’m glad to be a trailblazer for the community 😜

I didn’t even know what I did was possible. I tried my best to find something online that showed how to rekey a 140, and while I saw many posts showing the 140 as someone’s first pick, I didn’t find any videos showing the disassembly process. It never occurred to me that I could pull out the whole cylinder like that, using just a comb.

Thanks for that video link, it helped me understand a few things. I couldn’t see the caps on the side of my lock body, but I did see one on the front. I’ll take a picture later.

@thenetnetofthenet Usually there is a larger cap for shackle latches on one side near top. I don't have a 140... but image of an old G. C. W & Co. padlock that shows caps. Pretty much all brass padlocks with just a core fit into the body like that are built this wayšŸ¤·ā€ā™‚ļø

This is a four pin core, the fifth pin is for retaining the core and maybe limiting rotation.

It also looks like Master used a 5 pin core on your lock but didn't populate the 5th holešŸ™„

oh, I see. I was expecting them to be a lot harder to see. I can’t easily see these caps on the side of the body.

@thenetnetofthenet The rough sanding done when they're made hides the caps quite well.

Haven't tried this... I'd try sanding the side down to a smoother, shiny surface and see that helps to reveal themšŸ¤·ā€ā™‚ļø

FYI I did sand the side a little bit, but either I still need to keep going, or there’s something I’m missing. It’s not that easy to see in the pictures, but I am sanding some of the coating away for sure, and I feel like it’s starting to sand off some of the actual body material. I’m still not seeing anything close to your picture.

Oh well, thanks for the tips! I’ll keep the lock as a souvenir and at some point continue sanding and tinkering with it.

@thenetnetofthenet I looked at a new Master 140 in the store yesterday. Could just make out the caps through the plastic clam-shell package. How well they're hidden varies.

It's really vague... but it looks like one is starting to show here. Pointer is just touching the top of a caps edge, maybe...šŸ¤”
