What does immobiliser activated mean?
The immobilizer system is responsible for keeping the car from turning on with an unregistered key. If the system is not allowing you to turn on the vehicle with a registered key, it is likely because of the presence of a second registered key, an automated payment device, or an automated toll road device.
What causes immobilizer active?
Many immobilizer problems can be fixed simply by simply replacing the battery in the key fob. If the actual immobilizer system in the vehicle is to blame, then it could be due to the wires being corroded or damaged. Perhaps the engine control unit or its sensors are malfunctioning or faulty.
