Car Won't Start and Security Light is On on Cadillac Seville STS

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.

Every once in a while, I will go to start the car and it will start and turn right back off, and security light comes on!

No prende y la luz de seguridad se mantiene encendida. Revisamos la continuidad de la cableria y reparamos varios cables. Y ya funciona bien.
Last night car started fine now it won't start atall. It won't even turn over and there's this non-stop dinging sound even with the keys out and the door closed. And its a brand-new battery like 3 days old
