The locksmith pulls the barrel out, removes the old set of pins and puts in a new set with different lengths. Then the key is cut with bumps that correspond to pushing each length to the shear point of the new pin set.

Definitively not unique. Which is why it's not uncommon to find another key that fits.

The pattern makes big difference in trying to manually pick the lock pin by pin. Good locks will have very small room for maneuvering the lock pick.

Older locks, for example the one pictured above, have plenty of room for you to comfortably pick.

The zigzag is called the keyway. While they may increase security somewhat, they’re not unique. I think key manufacturers typically have a few dozen different keyways that they use repeatedly. That’s why every once in a while you may find a key fits into an unrelated lock.
