How is it that one key, different from others, can open the same lock assigned to the different locks?

Nothing on one, slight click on 2, counter rotation on 3…..
Inside the lock are a bunch of pins in a row. Each row contains 2 pins, one on top of the other. The pins are different heights. When you insert a key the pins are lifted. This aligns the spot between the two pins with the outer edge of the cylinder, allowing it to rotate. If the arent at the right height at least one of the pins blocks the cylinder from turning.
For locks with a master key there are three pins in each row instead of two. One of the spots between the pins aligns for the master key, the other spot aligns for the lock’s individual key. It basically allows two different keys to work in the lock.
If you are having a hard time visualizing it from my description there are tons of pictures and short videos available with a quick hoogle search.
