Founded by James Sargent in 1857, the Sargent and Greenleaf company is well known as a manufacturer of safes and vaults. But, how exactly do the combination locks that keep intruders at bay work, and how are they made?

The way the narrator pronounces “pentagon” reminds me of Benadict Cumberbatch pronouncing “Penguins” as “Penglings”

Search for "lock manipulator" on YT. He shows how to find the combination of a S&G (and others of similar construction). You don't need a stethoscope. It does however take some time until you become proficient. It's not rocket science.

Are these newer locks still crack-able with the Stethoscope breaking technique ?

Yes, can still be done. But it is not (and it wasn't in the past) quick and easy as you can expect.... you need a lot of skills and few hours of time to discover the combination (almost always more than a forced entry).

I think it would prevent a lot of people from opening it but I think that there are people who would be able to.

Ok so how are you supposed to know the code if it randomly selects it and no one knows the code????

Printed on the assembly sheet, next to the lock. Yes everybody in the packing line can see it, but once in a sealed pack and in a box hard to find without damaging the sealed pack. Plus you can change it in the field as well.
