For the vintage vibe, Ignition 911 in Gold, has been precision machined from the same material as the OEM factory Porsche key, 303 Stainless Steel. The only difference being that the key has been crafted in the USA. It has been PVD coated in gold to create a hard coat capable of withstanding heavy usage. It is extremely corrosion resistant and nearly indestructible. This key has been made to exact factory specifications and can be duplicated to your own key at any reputable locksmith.
