reprogramed new key now security effed?
ok i have an 06 cobalt i lost my keys and got a new cylinder and key, i tried to do the 30 min reprogram it worked somewhat, the car will turn over but the security wont turn off so its starting then stopping within a few seconds, i cut tha fuelpump and ran it to a seperate fuse to keep constant current and still it cuts off so im guessing tha comp is telling the fuel inj. to shut down.. so my question is why is my security light staying on even after i do the 30 min relearn procedure.. i changed tha tdm also and did another 30 min relearn with it.. im stumped any help would be much apprec>

your probably going to have to get the theft deterrent module reprogramed at the dealer. The ecm may need to be reprogrammed also. the tdm sends data to the pcm. if valid, the pcm sends a challenge code back to the tdm. there may be a problem in the message the pcm is sending back to the tdm. dealer reprogramming should fix it.

Do you not have a recall for the ignition switch and cylinder? if you do get her done and all will be good. you can go to gm website enter your vin to see if you have the recall.
or
30-MINUTE LEARN PROCEDURE
Turn ON the ignition, with the engine OFF.
Attempt to start the engine, then release the key to ON, vehicle will not start.
Observe the SECURITY telltale. After approximately 10 minutes , the telltale will turn OFF.
Turn OFF the ignition, and wait 5 seconds .
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes . The vehicle is now ready to relearn the Passlock(TM) Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
Start the engine. The vehicle has now learned the Passlock(TM) Sensor Data Code and/or password.
IMPORTANT: The vehicle learns the Passlock(TM) 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.

again if the recall has not been done just get it done and your problem will be solved.
