Starting with the Enzo, Ferrari then used that basic design on nearly all Ferrari's until they started delivering cars with key-less ignitions. Besides buying an original Enzo key (many $$), the options were limited to poor quality imports. I know, I bought one.
Just wanted to point out that if you have a Ferrari made between 1989 and 2005, there are now very high quality newer-style keys available for your car. These keys are blank (not cut) and the original key is easily duplicated onto it at any locksmith. The key head is solid acrylic. No cracking, no peeling.
