If the car is already started, you can usually drive it even if the key is not inside. However, most modern cars will give a warning sound or display a message indicating that the key is not in the vehicle. This is to alert the driver that the key might be missing. As a chauffeur, if you reach the destination and the owner cannot find the key, it's important to inform them about the situation.
