If the signal is not recognized, the fuel or ignition system is disabled, effectively immobilizing the car. Several factors can lead to car immobiliser problems, ranging from a weak key fob battery to a faulty immobiliser control unit. Common symptoms include the engine cranking but not starting, flashing security lights, and the inability to unlock the car.
