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.

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.

My car won't crank or anything. When I put the key in the ignition all of the electrical stuff works but when I go to start it the Seville does nothing. On the dash I see a red battery light and I hear clicking from underneath the back seat. It did this twice before but only lasted a few seconds then started. I've only had the vehicle a week or two and don't know too much about cars let alone Cadillac's. Please help.

just wouldn't start one morning "Starting has been disabled due to Security System". We had a number of different people start using the car so I thought maybe a wire broke in the steering column since the tilt had been being used more than normal for a week or so before the issue. got out my ohm meter and looked up wiring pictures for the securitysystem, cut the key reader wires after they exited the steering column under the dash and crimped a resister inline that matched the resistance on the key pellet. Car started right up when I turned the key this time. Only downside is the car always thinks it sees the right key now so anyy key cut to turn the cylinder will start the car.
