Many locksmiths, including most big-box home improvement stores (who no 
longer keep a decent array of keys), will cut a duplicate of a key that 
has a piece of masking tape over a "Do Not Duplicate" stamp!
It is illegal to duplicate a DO-NOT-Duplicate key for anybody too stupid 
to cover the staamp.

Howzbout: list any that are reported, and a count of how many report that 
particular info.  That way, a single instance provides a hint of possible 
inaccuracies (easy to do), or even completely different than standard 
lock.   A dozen people reporting identical data is a pretty good 
confirmation, and if it doesn't work for you, then YOUR lock may have been 
replaced at some point.
If only one other person has that machine, I'd rather have their 
unconfimed measurements than a void in the database.


BTW, a decent machinist could easily build an Ace lock picking tool that 
is calibrated - the sliders could be set to me the same depths as any Ace 
key.  Without knowledge of commercial availability, I designed one (but 
didn't build) in high school half a century ago.
