A method for using a vehicle system that has stored a portable identifier is proposed. The system and the identifier are configured to communicate using a UWB communication protocol within a first perimeter around the vehicle and to communicate using a BLE communication protocol within a second perimeter that includes the first perimeter. The method comprises, while a user carrying the identifier is approaching the vehicle, detecting that the identifier is located within the second perimeter and performing two distance measurements between the user and the vehicle. The method then comprises determining a speed of the user and predicting a time remaining for the user to reach a predetermined near distance from the vehicle. After the predicted remaining time has elapsed, the method comprises initiating a communication using the UWB communication protocol. The method provides for improved use of the portable identifier.
