If both of your keys do not work (turn on but no start, red LED comes on), the PATS system needs reprogramming by the dealer or a locksmith, unless someone else comes up with an idea! This topic I found on google may give you some information:

Good luck, I hope you get that fixed soon and at a reasonable cost...
