Please let us know what happens.

The only thing you can do is have the dealer diagnose the problem. You can't bypass it and they are the only ones that have the proper test equipment to check it.

I wish I had better news, but that is it.

Let me know if you have other questions.

If the security light is staying on and preventing the engine from starting, I hate to say it, but you need to take it to a dealer. They are the only ones that has the proper test equipment to check and diagnose the problem. Also, they need to reset it.

Let me know if you have other quesitons.

Probably need to have the BCM scanned while it is going off if possible to find out what the Anti-theft controller isnt happy with. Is this a factory alarm or aftermarket?

Could be the ignition switch itself is bad, or the key sensing part of it. How are you at testing with cotiniuty?

A TSB means they know about it, and are helping thier mechanics, but it's not a recall, so you pay for the repair.
