Meaning that the XX2247 key would have depths (in the order you
describe) of 5-1-7-3-7-5-7
A locksmith set up for ACE cutting would have the code book to convert
the serial number into the depth sequence, so the number on the key is
the important datum. Knowing the numeric depths is handy when you are
pinning a lock so you know which bin to pull pins from.
Thanks to all who helped. We have now confirmed that XX2247 is a code
number, not the depths, for looking up in a code book.
Ethan's decode eliminates the need for a code book.
(5-1-7-3-7-5=7 is what the locksmith would find in the codebook.)
(You can now put that number in your phone number list :-)
Ethan's and Pete's depth chart and measurements eliminate the need for a
depth chart for cutting with a drill press. The spacing can be figured
out from any other 7 cut key, and is presumably preset on a tubular key
cutter. Now, where the hell is that Hert-Gerty?
Pete's other measurements are almost enough to MAKE a blank.
The XX2247 is now fully documented.
