Number Theory/Duplicate key making machines.


Dear Prof Scott

Are there duplicate key making machines available in the Market?.


I'm not sure what is meant by a duplicate key making machine.

Do you mean a key pad for a machine that has duplicate keys?  If so, keyboard for PCs already have them for the numbers 0,1,2,3,4,5,6,7,8,9,<enter>,<shift>,'.', and even more when necessary.
Keypads with different duplicate keys are also in use at many stores.

If you mean a machine that is able to duplicate another key pad, they have those too.

If you mean a machine that has the ability to produce many keys of the same symbol,
they have them as well.

Whatever is meant, they most likely already produce and sell them to various grocery stores, retail stores, car dealers, mortgage places, schools, and whoever else needs them.

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.


I have known about number theory since the mid 80's. I have answered over 250 questions on Number Theory with this software. Altogether, I have answered over 8,500 questions in mathematics.

You're looking at it ... I've answered over 8,500 quesitons in mathematics right here.

My credentials are an MS in Mathematics at Oregon State in 1986; I received a BS in Mathematics at the same place in 1984.

Awards and Honors
I graduated with honors in Mathematics when getting my BS degree and my MS degree.

Past/Present Clients
I have assisted many students in mathematics at OSU. Perhaps I have assisted one of you're friends in math on a computer somewhere else, but you don't even know... That would be late last night, perhaps with thousands of miles between us ... Then again, if you're in Washington, so am I ...
