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

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.

2001 Cadillac Seville SLS 74,000 mi,
seems to keep drawing power from the battery after you try to start it. Low voltage, clicking, service theft system pops up, radio goes wacky, sometimes seat moves. Will only start if jumped (battery is ok and new alternator) Latest issue, dash wont turn on even if car starts. Neither will temp control.
