After completing the 45 minute relearn procedure for a 2004 Pontiac Grand Prix message center Now says system not programmed

Relearn for what ? Anti theft system PK3 ? The relearn procedure is three 10 min. procedures for a total of 30 min.
30-Minute Relearn Procedure
Use this procedure after replacing the following components:
The passkey III (PK3) keys


The PCM, see important above

Important: This procedure is not available on vehicles equipped with option code (Z49).
If replacing a BCM with an GM SPO Replacement Part, perform the procedure to setup a new BCM prior to the 30-minute relearn procedure.

  1. With a master passkey III key, turn ON the ignition, with the engine OFF.
  2. Observe the STARTING DISABLED DUE TO THEFT message on the drivers information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
  3. Turn OFF the ignition, and wait 5 seconds.
  4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
  5. Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
  6. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
  7. With a scan tool, clear any DTCs.

Anti-theft light not flashing new fuel pump went in store came out no start.theres no spark,and theres no fuel the just turns over,but wont start

this sounds like the anti-theft system has activated not allowing you to start car.the system shuts down spark and may need to reprogram the key to the car again.i think that if you turn the key in the on position for 3 minutes then off wait for 5 seconds i think and back on for 3 mins and off and again one more time.the 4th time you should be able to start the car.

Hi I own A 98 Chevy Malibu, my ignition locked n i had to put a new ignition switch in, well now my cars tellin me Something Theft Service. Im wonder what I need to do? Iv unhooked battery for hours ect...

You need to reset the theft system. To do this, try to start it. It should start and die. Then after it dies and the theft light is flashing, leave the key on for 10 minutes. After 10 min, the theft light should go out. After the theft light goes out, turn off the key. Count to 5, then restart it. Then it should work.

94 cadillac will not start or turn over because the security light blinks on and off. had a new key made at the dealer and performed the relearn procedure..I put the key in the RUN position...

As the prescribed method isn't working it would seem likely the antitheft system is broken and should be checked by a professional.

Electronics aren't bulletproof and at over 20 years old the ones fitted to your car are 20 years less robust and 20 years less sophisticated and easily damaged by such things as welding, battery charging, jump starting or even nearby lightning strikes. Such instances often do not cause obvious damage immediately but rather have a weakening effect so the final breakdown happens later, maybe years later.
