When the security light comes on in a 1994 ponitac Bonneville and the car will not start what do you do?

Answer 1

If you have a resistor embedded in your ignition key, it means your vehicle is equipped with a theft deterrent system, and from experience, the most common problem is a severed wire at the ignition cylinder. This would normally require replacing the ignition cylinder, which could get quite expensive because not only does it require replacing the cylinder, but would also need to cut new keys with the same resistence as the old keys. Keys cost in the $20 to $30 range, each! This cost is in addition to the cost of labor and the ignition cylinder. The way to fix this problem without replacing anything is simple: 1st, measure the resistence of the pellet embedded in the ignition key, using a digital volt/ohm meter. Then go to your nearest Radio Shack and get a resistor/s to match what you measured on the key. Then, cut the two thin white wires at the base of the steering column, the wires lead up, into the column and to the ignition cylinder. Connect each end of the resistor you got from Radio Shack to the wires you cut at the base of the column, doesn't matter how you connect to the wires. What you are doing is bypassing the resistor embedded in the key. good luck.
