You create a digital key through the mobile app. However, you must have your key card with you and be in the vehicle. You will also need your Volvo ID on hand.
Access the mobile app and follow the instructions.
When the vehicle display gives you a notification to do so, place a key card on the card reader located between the two front seats.
Follow any further instructions in the app or the display, such as scanning a QR code on the display with your phone.
To save some customized settings, you should assign a key to a profile.
