For some reason, the factory anti-theft device has cut off the starter and it would not let me start the car. When I turn the key to "start", the engine does not try to turn over at all. When I open the hood, I can hear a quiet high-pitch noise when key is turned to "start", and that's all. All the accessories, such as stereo, radar detector, work fine when key is in "on" position. I have to hold down the override switch to start my car. Furthermore, the remote entry/anti-theft device has been completely disabled. Technician at the dealership said the "brain" of the alarm system, or the control module needs to be replaced because it's simply dead.
