He described the basics, in regards to the XX2247.
With a code book, the key number (XX2247) is all that is needed.
Without a code book, but with depth and spacing info, the list of cuts is
what is needed.
Without depth and spacing info, the depths of the cuts are needed, along
with where to put them.
Since we can not assume convenient acces to code books or even depth and
spacing charts, (any locksmiths here besides Ethan's brother?) we should
keep track of all three levels.
