That is indicating the Anti Theft system is engaged. If could be for many reasons. I hate to say it, but a dealer is the only place that will have the proper test equipment to diagnose the problem. If you have a different key, try it. Sometimes the sensor in the key goes bad. If that doesn't help, then you need to see a dealer.
