_presuming_ they can code-cut a 7-pin round key (not a universal
expectation). My experience with code-cut keys is that a) they cut it,
you pay, fit or no fit, and b) it's a few $$$ more than a copy.

Old Fred, XX2247 isn't the depth cut of the

"XX2247" is a "CODE NUMBER". Notice that it is SIX digits, two of
which
are 'X's. (which is NOT normally a cut number). The digits of "XX2247"
are presumably COMPLETELY arbitrary, and serve to identify a given code,
NOT give you the depths.
(There ARE rare exceptions, where the code number and depths are
algorithmically related, such as 1975 Honda door keys where the code
number is just the list of depths in reverse order. I don't see an
obvious algorithm. "XX" COULD be a "don't care, no pins in those
slots",
but we would still be missing one of the seven? cuts.)
X X 2 2 4 7 is presumably the INDEX, not the VALUE (seven ints)
stored in KEYS[XX2247]
int KEYS[][7]; /* look up that key, get cut numbers */
/* apparently 7 spaces for this model lock */
float DEPTH[10]; /* look up each depth number to get distance */
/* # of different possible depth cuts may be */
/* other than 10, but is a constant */
/* for the particular model of lock */
A well equipped locksmith can look up "XX2247" in a "CODE BOOK", and
receive a seven digit number, where each digit IS referring to a specific
depth. Then, a quick glance at a "Depths and Spacings" chart will provide
the actual depths of each cut number, although most code-cutting machines
have databases (often in the form of dial cards) to look that up for you.
If somebody MEASURES the cuts, or looks up "XX2247" in a CODE-BOOK and
looks up the seven depth numbers in a Depths and Spacings chart, and then
POSTS those depths, then the key can be cut manually (drill press
recommended, if an appropriate keycutting machine is unavailable).
