When you try to start a car with an immobiliser and the key isn't recognized, the engine won't start. Immobilisers are security devices that prevent the engine from running unless the correct key is present. They do so by disabling at least one of the systems needed to start the car, typically the fuel supply or the ignition. If your car doesn't start due to an immobiliser issue, ensure you're using the correct key or fob, and if issues persist, it may require professional diagnostic services to identify and resolve the issue.
