Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

The security light started coming on and staying on and as long as its on the car won't start. It literally just happened one day while I was at work. I can see my car the entire time while I'm working so nothing was done to it. I just went out to get in and it wouldn't start. The problem is still not fixed.
The car periodically just won't start - No noise, nothing. The battery is good. Then wait some time - 5 minutes, 2 hours or whatever - and it starts right up. There is not pattern to it. It happens at random times. Sometimes it goes a long time before it happens, and at other times it happens more frequently. Very frustrating when it does happen though.
