Changed ignition lock switch and now the car runs but theft system light will not go out. What do I do?
Change the whole system(anti-theft system). this costly solution gives you the dealers warranty.
and/or
if you just want to disable the system permanently,cut the yellow wire on the steering colume.

Measure the resistance of the chip in your ignition key with an ohm meter.
Purchase a resistor of the same value at Radio Schack and wire that into your ignition lock cylinder wire harness.
You will find this harness near the base of the steering column. Two very thin white wires with an orange connector end.

Try this first, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help

Take it back to the guy that installed the alarm system cos mine runs 3 LEDs & its fine

Had similar problem that is a seemingly impossible to bypass (tried 1500 ohm resistor and still could not match the electrical current in the anti-thefy system) so standard pice wont work. But if u swich the whole lock cylinder from another grand am it should work becuase it has the same electrical current is flowing wich needs to be active at all times for the car not to shut off right away (there is no chip in the key at all)

i have a 1997 pontiac grand am and it did the same thing when you go to start car and it won't start after 3 trys you have to turn the key to the on postion and let it set for 11 min no more then 11 min then turn it off and count to 30 then it should start. there is no way to go around this wiring .i have asked everybody also if you disconect the battery for a while and hook it back up that might reset the computer and that will work that is what fixed mine for now its been 6 months and hasn't done i sense
