If the car has been stolen then the owner can contact a Volvo On Call service centre (via phone or the Volvo Cars app) or the authorities.
This also applies if the car was opened and stolen with the associated key.
After having been in contact with the authorities, the Volvo On Call service centre deactivates the keys in order to prevent the car from being started. A deactivated car can only be restarted by contacting Volvo On Call service centre and PIN code verification. Following which, Volvo On Call service centre performs activation of the car.
