In 2017, Volvo will replace the traditional car key with a Bluetooth based smartphone app. The app will automatically unlock the driver’s vehicle when they walk up to it and lock when the driver parks and turns away. The team at Volvo believe that this will give driver’s remote access to their car, and make rental car collections easier and more efficient using this digital key. Also, security concerns were dashed with Volvo stating that a stolen phone is safer than stolen keys. Volvo will trial the new technology in spring at its car sharing firm Sunfleet, based at Gothenburg airport in Sweden. If successful, a limited number of commercially available cars will be equipped with the new digital key technology in 2017.
