I've used a Combination Lock for years but I've never really understood how it works until I made this video. The combination lock that I used in this video was from Master Lock but there are other companies to make them too. Parts of a Combination Lock include: Case, Shackle, Shackle Collar, Lever, Latch, Cams, Washers, Spring, and the Backplate.
This video has been dubbed in over 20 languages, you can change the audio track language in the Settings menu (click the gear icon in the lower right hand corner of the video).

That was glorious. I could watch videos like this all day. Didn’t know exactly how it worked before but now I have a really clear mental model in my head. And I love a good mental model.
-
My mans researching how a friggin lock works and animate it for hours so we can enjoy it in 6 minutes.
-
I love this guy because he explains things so well. If I actually tried to explain something I would horribly fail and everybody would be confused.
-
How a Master Lock works: 1. And it's open.
-
What about locks that you can set the combination yourself? How does that work?
-
Time for bed I have school tomorrow YouTube: how do combination locks work? Me: Good question!
-
Whoever invented this was a goddamn genius.
-
One thing that was shown (but not talked about) during the 'how dial sets code' animation was the first disk having bumps/notches in it. I believe they are called 'gates' and their purpose is to make it more difficult to pick the lock by lightly pulling on the shackle, spinning the dial, and feeling for true notches to line up under the latch.

"This is the LockPickingLawyer and today we have..."

You modeled, animated, and made this whole video in 60+ hours so we can enjoy 6 minutes of it? Damn! I give you respect and a sub for that! Absolute dedication.
-
Really good animation. There's something you might have missed though, cos it's not that obvious. When you pull the shackle open, past where the locking lug is, the edge of the shackle retainer clip also knocks the combination rings and moves them all out of place. (That's why it's shaped a bit weirdly).
-
This has been explained to me several times over the years but without a visual, my grasp on this concept was fuzzy at best. Thanks for the time you took to make this!
-
Do a collab with the lockpicking lawyer on how picking one works
-
Very cool animation! But all of this doesn't help me since I somehow always manage to forget my code 😀😀😀
-
Being able to explain things vividly and thoroughly is a skill many, many, many people lack. You're a great communicator and I dig that.
-
Great explanation! One note I have at 4:40 is that the jolt from locking it often isn't enough to move the cams out of alignment, and so unless you turn the dial again to move them, there's a good chance your lock will just open if someone pulls on it
-
Now everytime I open my lock imma think of this
-
Your videos are amazing :)
-
Wow, that was great! After opening a locker multiple times per day for all those years in school, I finally know how the locker combination locks works. There are so many things that we take for granted but don't know what is actually happening behind the scenes.
-
You’re a great teacher Jared. My mind is blown! I never knew how how it worked but now it’s simple.
