How a lock works explained in one perfect cutaway video

I'm a big fan of cutaway things, specially if they are real like this lock. It's fascinating to see how machines and mechanisms work, with the little pins and springs moving to fit the shape of the key, leaving the barrel free to move when everything clicks.

Much more satisfying than the good old 3D animated version.

Good video. It would be nice if it also included a lock that has had master key setup in it. Looks the same but the pins will be split in various locations to make it work with the main key and the master key.

Keying locks can be Pretty fun.
