Lock on dixie narco

I bought a dixie narco machine at an auction yesterday.  I do not have a key for it.  How do I get the machine open without damaging the machine?  The lock is a standard circle key lock on a DC 150-5.  The machine is beautiful and runs, but I would love to get  look on the inside before I resell it.  Can anyone help?

I wrote a quick "how to" on drilling out and replacing these locks.  Hope this helps!
