Gianni,
I only had one ignition key for Renee. That made me nervous, so I looked around for a place to get copies made. I had no luck at any of the local key merchants. A co-worker suggested
www.keys4classics.com. I wish I could find the original information and sales person but I can't. I had a conversation with them via email, and they eventually suggested an Italian made blank, after I scanned my old key and sent to them. The new keys are labeled "Silea", "Italy", "NE10". I was able to find the key cutting code on my old key, a six digit number. They used that number to cut the key blanks. The keys they sent work well. I would suggest you forward this information and see if they can help you out. You might mention my name, in case they have my order information still in their computers. This is, of course, assuming that your boat and mine have common key blanks.
