UPDATE:

TLDR; The answer to my question is – you don’t 😜.

Thanks to everyone that entertained my question. It seems that without drilling, it would require a seemingly impossible balancing and compression act to slide everything back in.

How do I reassemble a Master Lock 140?

Black Friday was my excuse to finally get some lock picking tools. After trying an acrylic lock and a practice lock, I decided to go after one of the Master Lock 140s that I had laying around.

I was able to get it open with a single pick and then a rake.

Then I tried a comb. I went from “yay it’s turning”, to “oh, it’s really turning”, to “uh, oh, it’s still turning”. 🤣

Not really realizing what was happening until it was too late, I ended up removing the whole cylinder (is that what it’s called?) as pins fell out, without paying attention to which pin goes where.

The shackle wasn’t actually unlocked at that point, so I fiddle around inside the lock some more and fully unlocked everything.

I assume I inadvertently started the process to rekey the lock, but now what? How do I put everything back together again?

I know the pins are out of order, but I assume short key pins go with the taller parts of the key, so I’m thinking it’s something like 1+B, 2+A, 3+C, 4+D. I seems like 5 only fits into #6.

My main questions are: (1) Can I just shove everything, or do I have to worry about whatever it was inside the lock that actually unlocked the shackle? I don’t know if it has to be in a certain position or not.

(2) From using the CI practice lock, I assume the process is to put in the key pin, pointy end down, then driver pin, then spring. Is that right?

(3) Do I start from the back (i.e., #6), putting the pins in, pushing the spring down and using the lock body to keep the spring compressed?

(4) Related to (1), does the cylinder need to go in at a certain orientation (or avoid a certain orientation?

(5) Finally, what is the correct pin order if I want to keep using that same key? Was my guess correct, 1B, 2 A or C, 3 A or C, 4D?
