I have zero knowledge about the topic and something in the video confuses me:

In the YouTube video explanation around 2:30, when individual positions (not sure if it's the correct word: talking about the different parts of the lock's inner array moving based on the position of the key/pick) are picked, why doesn't the inner mechanism at snap back to its initial state by the spring's force when key/pick is moved out of that position?

And how do they reset when lock is turned and unturned back to initial rotation state if they don't reset when individual positions are released?

(Sorry if I used a terribly wrong terminology)




The pins usually don't fit exactly (because they still need to be able to move up and down), meaning that you can turn the lock slightly even without the pins at the right positions.

If a pin is pushed up completely, and you turn the lock slightly, the pin can get stuck in the right position. This is done with a torsion wrench, keeping torsion on the lock while trying to get the pins in the right position with picks, hooks, or rakes.
