Do you have a remote button? If so close and lock the doors. wait 30 seconds and look at the security light, it should be blinking. Unlock the doors and try to start the car, if it starts the alarm system is okay and reset. If not repeat proceedure with the key. Go through the steps carefully, any change will not work and you will have to start over. Thanks, Joe

HelloCustomer if your vehicle has activated the theft deterrent system then try this and it should be fine if that is the only issue:

  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON (vehicle will not start).
  3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds.
  5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the password XXXXX the next ignition switch transition from OFF to CRANK).

    Important: The vehicle learns the password XXXXX 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 password).
  7. With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).

Is it possible you crossed the jumper cables when jumping your car? Thanks, Joe
Customer: replied 7 years ago.
No I had positive on battery and negative on frame.
Expert:  JOES SHOP replied 7 years ago.

You may have a different problem then the alarm. Try to reset it again if it still does not work we may want to confirm the problem is in the alarm before we go further. Thanks, Joe
