I can cut a key by the code.
I believe your in Canada, me too.
$20 mailed to you.
Finally, I don’t need a 818 key anymore as I decided against restoring the Z1-R and I sold it. However, I do have quite some 1981-1984 KZ that needed some spare keys. I contacted rstnick that cut all of them accordingly to the "zxxxx" code stamped on the OEMs. I received the keys very fast and all of them works perfectly. So, do not hesitate to contact him with any of your keys request.
