Hi Guys, thanks for all the help.
Yes, I don't really want to destroy the locks.
I have had some luck (I think).
The original .US supplier has offered to get some keys made.
However there is a 2 week lead in time, plus shipping time from .US to .AU.
Is US$11 each an OK price for these?
I have to order a rather large qty but I'm prepared to wear that.
The blanks supplier refuses to ship outside the USA.

I would have been interested in getting these blanks regardless but what can you do. I really can't understand the attitude of some USA sellers. It all goes through the exact same USPS store who cares if it's going to .AU instead of .US personally I think it's an elitist attitude.
I have asked the guy with the key to give me a picture looking down. He is pretty slack though and tends to be difficult to deal with.
See if he eventually comes through.
It could be a month or more before I know if I will have an outcome.
But I'll let you guys know how I go.
