A method for operating a start and entry system of a motor vehicle, including the steps of: detecting whether an authorization of the starting of the motor vehicle is carried out on the basis of a key signal received on the vehicle side, which has been sent from a transmitting and receiving unit of a vehicle key, or whether the authorization of the starting of the vehicle is carried out on the basis of a near-field signal received on the vehicle side, which has been sent by a near-field communication system of a mobile communication device. If the authorization of the vehicle start is carried out on the basis of the key signal received on the vehicle side: the start and entry system is operated in a key operating mode, in which, following the starting of the vehicle, only the availability of the vehicle key in a vehicle interior of the motor vehicle is monitored.
