I can't look at the pictures from work But I think you are referring to this key http://www.cloverkey.co.jp/product/collection/index.html also here is the process on how they make it http://www.cloverkey.co.jp/product/collection/popup/gk_process.html It's made by the Japanese company called Clover Co. Ltd You simply send them a picture of your OEM key and they'll cut one for you . It's a nice key ,Since I has one for my RX-7
Thanks for the info mate. When you see the pics you will notice it's different to the one you linked. But is from that company. How they make them and the detail they put into them is amazing. Beats the 2 cent keys that get batch made in the thousands from china or Malaysia etc. Shall have to keep ours safe. Nice little momentum to go with the oddities of our zed.
