MemphisMan Posted March 17, 2011 Report Share Posted March 17, 2011 Welcome to the forum. I'm sure you'll find the answer to your issue here...it's just not going to be me because I don't have a clue on what you need to do. The forum members collectively know these cars inside and out and they're a great bunch. Quote Link to comment Share on other sites More sharing options...
MonteCarloChick Posted March 17, 2011 Report Share Posted March 17, 2011 You'll needs to bypass the VAT system. search google for vatslikeabigdog. There's a great writeup. It's very easy to do. I did it very quickly. I'd link you now, but I'm on my phone lol Oh, and welcome! Quote Link to comment Share on other sites More sharing options...

Welcome aboard!! If the problem truly is the passlock system, and you're not a do-it-yourselfer (no that there's anything wrong with that), audio installation places (specifically those who deal in auto-starters) are the best place to go for help bypassing that stuff. Also, I would consider the key suspect, I have a suspect one myself, and it doesn't always want to start the car, and the security light will come on infrequently while using it. Fortunately I have two others. I'm not sure if there's a way to test the key, but it's been known to happen. Quote Link to comment Share on other sites More sharing options...
MonteCarloChick Posted March 17, 2011 Report Share Posted March 17, 2011 You can test the resistance between the chips to see if they match up. Most times it's the reader in the ignition Quote Link to comment Share on other sites More sharing options...
