To order a key you will need to take your registration (Proof of ownership) to your friendly dealers parts dept. I also had to show proof of insurance(why I don't know). Keys are kinda pricey and they come in a few different configurations. There are master keys w/ & w/0 light, valet keys, and emegency plastic wallet keys. The plastic emergency key was something like $68 which was cheaper than the right side door glass that I had to break since I didn't have the emergency key. )c;
