How do you start your land rover discovery 1 when the car with a key dashboard light is on?

If the "car with a key" dashboard light is on in your Land Rover Discovery 1, it indicates a potential issue with the immobilizer or key recognition system. First, ensure that the key is functioning properly and is not damaged. If the key is fine, try using a spare key if you have one. If the problem persists, you may need to consult a professional mechanic or a dealer to diagnose and reset the immobilizer system.
