How Is A Combination Lock Made? | How Do They Do It?

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 Lock Picking Lawyer: Are you challenging me?

[@davidlarson2534]

All locks are pickable (I’ve seen a few of your videos). At 12 I picked all the locks on my elementary school campus, even the safe. In the Air Force I picked the 5-combo dial top secret vault in our shop. Who’s gonna call the commander at 2:00 in the morning? Hehe. Yet, while watching this video I came with a new lock idea that would be unpickable.

These 'How they're made videos are so fascinating to watch!!!

[@cgamejewels]

I did that with a combination lock i got for school and was surprised it worked. I forgot my combination. 😂😂

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

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

[@SeanBZA]

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.

cracks me every time

[@Lyf4rMusic]

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

[@vizor4u]

Asking for a friend I guess?

[@teslacoiler]

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).

1:50 If I put a mechanical clock that makes a loud ticking sound, will he able to open it?

[@luchvk]

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

[@JeepinBoon]

Yes, absolutely. No reasonable amount of noise can prevent detection. It's more than ticking you gotta pay attention to. You gotta watch the width of the lever gate. It all depends on the quality of the lock. When the fence falls into a gate, the lever gate usually becomes narrower. S&G's are fine locks and are quite difficult because their fence doesn't touch the wheel packs when turning. Audible cues are almost never present on modern good quality locks. Cheap/antique safes sometimes can be defeated by audible cues alone. Some, by feel alone. I love safe cracking!

[@lockolot6704]

@@JeepinBoon uh have you ever cracked a safe😂 the fence is always touching the wheel pack on S&Gs

[@JeepinBoon]

@@lockolot6704 You are wrong. The fence of the S&G is raised off the wheel pack by the drive cam and only allowed to contact the wheel pack at a very small degree of rotation. Please do not use sarcasm as you know very little of what you speak.
