HelloCustomer if your vehicle has activated the theft deterrent system then try this and it should be fine if that is the only issue:
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.
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
P.S. do you have test equiptment?
