Anti theft system

In the head of the key there is something like a chip that sends a signal to a sensor in the ignition switch. This is how the anti theft system detects theft by an unauthorized key. What I am thinking is the computer has been disrupted by the broken key and maybe you can reset the system by disconnecting the battery for say five minutes and try again. I'm not a computer nerd so this only my best guess. I hope this works for you.

I have actually tried that but I could try it again. I called the service department her in Corpus Christi were I bought the car and the guy Mike Perez. He spelled his name for me. Was a real jerk. He said there's no warranty. He said it was my fault not the cars because I was trying to inquire about a defective system or part maybe and the only advice without even so much as a care he said just bring it in and we'll look at it. He said its $155 an hour !! And then maybe they can tell what's wrong. He said that was just to look at it. Then he could give me a price on what it would take to fix it. I was so flabbergasted. The service department is not available. They don't call you back and when you do talk to somebody. I got him ... lucky me. Anyone with any advice. I'm desperate
