I had the same problem.
One morning the skim doe's not recognize my key.
I had a few "experts" look into it.
1 said I need a new 700$ part(not the computer), which I can get only from the dealer - "yeh, sure"!
I tried buying some more keys and cutting them, which was not easy as older car models(need special key - I got from ebay 13$, need special code locksmith could get - paid 40$ a key to cut. One dealer wanted 200$ for 1 key!).
Turned out wrong diagnostic.
Eventually I ended up buying a new computer(rebuilt of course).
After checking the dealer 700$ without installation! I found an online store both on ebay and web
www. Autocomputerexchange. Com
i bought for 200$ a computer programmed to my exact car(they require to send the old one after you receive the new).
By the way you could get it for 70$ or so less if you send yours first, it will just take longer of course.
Installation is a peace of cake, but I paid some one 100$ never the less.
Problem solved for me.
Good luck
