Did you have the 2 original keys that came with the car? From what I understand you can only add more keys if you already have the 2 originals, otherwise you have to go to the dealer to have them reset the key list on the vehicle's main computer.Well, that only took me three months.I ordered a pair of keys through eBay for about $12. My local Ace hardware cut them for me (for free!) after warning me that if the keys didn't work or the chip was damaged they weren't liable. Programming them per the owners manual only took a couple minutes and they both worked fine.
