This key is made of platinum, onyx, and a whole lot of sparkly diamonds that make it look more like some kind of jewelry than a car key. It was made by Optimal Innovative Solutions, which is the same company that makes the diamond hood ornament for Rolls Royce.
There are 40 carats of diamonds on this exclusive key which isn’t a factory option just yet. There’s no official price, but estimates put it at around $250,000 which make it possibly the most expensive car key available.
This is a one-of-a-kind right now, but Koenigsegg will surely offer it up to anyone if they feel there’s enough of a demand. If you’re going to get a supercar, might as well have a key that’s just as impressive as the car, which itself costs $2.8 million.
