ACE Key codes (xx2247 etc.)

I have one of those dang round keys on my Nicolt 1080.
I just took the lock out to a real lock smith and he made two keys
for it in a day for $25.
I regret to say his shop has moved or he quite the business.
I took another lock to another shop an they said they didn't
have anyone that could make a key for it.
I guess they were just the key copy and tumbler replacement
type lock smith.

I can only increase the sample size by one for the moment, but my System
Three does indeed use XX4306.  I have access to a pair of Z2 machines in
a few days, so I can check them too.
