The igniton key will have to be coded for the car as well as any remote fobs you have. If you are going to change the igniton you might look on EBAY and buy a batch of keys and fobs so you can have a few spares. The dealer will code as many as you want for the same price so you might as well get as many as you want when coded. You will find that batches of keys and fobs are very cheap on EBAY. Just make sure you are getting OEM keys and fobs.
