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

It is not about the key. Nothing about the key is special.
It’s all about the lock. The lock’s “code” is determined by the length of the pins.
By putting multiple pins in the same hole, we can allow for two (or more) different key cuts to rotate the cylinder. A building with a master key has every lock set to use two different key cuts. One of those key cuts is the master key cut.
