If you don't have two working keys then you will have to go to the dealer or to a locksmith with the special equipment needed to program these types of keys. This will cost you from $20-$40 to have this done. If you already have two keys then you can program it yourself for free! Your only cost is the price of this keyblank and the cost of getting it cut.
