Abstract
A key blank for manufacturing a key for a disk cylinder having rotatable disk tumblers has a key shaft that extends along a longitudinal axis. The key shaft further has a plurality of notches that extend transversely to the longitudinal axis, that extend at equal spacings from one another, and that have the same depth. In a key, these notches may form chamfers of drive slopes for driving the disk tumblers.
