Problems with the 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 the key and ignition lock cylinder must be replaced to correct this condition.

Same problem with key. Mech. thought it was the starter but even with a new one no starting at all. They tried to re-program but no positive results at all. Put it in neurtal and started once but would not start after. My Security light was on for about 8 months prior but no problem starting the car at that time. Security light turned off for about 3 weeks before this so I thought it was OK-reset.

Took extra keys/items off key ring so that car key and house key are only objects on key ring. No problems since then (almost 6 months ago).

I tried to start my car, it was in perfect working condition, and it wouldn't start. I took the key out of the ignition, put it back in, made sure I had it in park and it started. Now the Security light is on all the time. After reading this page I know what to tell my mechanic to fix it!
