security system prevents car starting
Jaguar vehicles come equipped with anti-theft systems that may prevent the car from starting. If the key fob isn't recognized, the immobilizer feature can disable the ignition system. Try unlocking the doors manually with the key fob to reset the system. If your Jaguar car doesn't start, it might be due to a dead battery in the key fob, or a problem in the immobilizer system. If the problem persists, the vehicle may need professional diagnosis and repair, possibly in a Jaguar authorized service center. Remember, trouble with starting your vehicle might not always be due to the security system; it can also be a more standard mechanical problem.
