Why does my car say immobilizer but does not start?
If the battery is low then there will not be enough voltage available in the car to deactivate the immobilizer system and start the vehicle. If the battery is fine then I would try an extra key. If the extra key does not work then the immobilizer system needs to be reprogrammed to see if it is a programming issue.
What happens when you put the ignition key in the Immobilizer?

Is there a button to disarm the immobiliser?
