Report: Car Won't Start Because of Anti-Theft System That Uses Raised-Chip Key
Cadillac Seville STS Problem
Average Mileage: 125,500 mi (82,000 mi - 160,000 mi)
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.
