The gold "CVO" keys can still be ordered through dealerships, you'll need your key code and the CVO VIN to
Don't have the p/n in front of me, but it's in the back of the P & A catalog along with the other keys.
I believe that they like $70, and you can surely find a dealership that will offer 20% off the list price.
Some people apparently like keeping them for jewlery or momento's.....figure that one out. You can also probably still order the CVO cover for a while longer, but you'd have to get the p/n from someone for your particular model CVO.
