![]() ![]() Mobile UI is an interface between OEM/TSM and the smart device. It enables service providers (OEMs) to distribute and manage their contactless applications remotely by allowing access to the (embedded) secure element in smart devices. Here, TSM stands for Trusted Service Manager. The high-level architecture from the Car Connectivity Consortium including the interfaces to be standardized. The European version of the Mercedes-Benz E-Class and the European version of the 2019 Audi A6 both have phone-based digital keys, but both systems use near field communication (NFC) to operate. The Lincoln Aviator now has an app that will unlock the SUV and stores driver profiles for comfort settings. They were also able to drive the car away without the phone being inside.Ī few other carmakers are beginning to roll out digital keys. CR testers found they could start a Model 3 when the phone with the digital key app was five feet outside the driver’s door. Traditional RF keyless entry fobs generally must be inside the vehicle before the car will start. And it explains why many observers expect most cars with digital keys to still come with key fobs for the foreseeable future.Įxperience with the Tesla implementation also indicates there are range issues to be worked out before digital keys go mainstream. ![]() Because the Model 3 doesn’t come with a traditional ignition switch or push-button start, drivers must also tap the key behind the front-seat cup holders to “start” the car. To lock or unlock the car, a driver must swipe the keycard along the pillar next to the driver’s seat. Tesla provides Model 3 owners with a backup keycard that can also be used when the car is valet parked. Tesla’s use of digital keys shows how the industry may handle scenarios such as how to open the car door when your smartphone battery dies. CR reports its testers occasionally found themselves unable to open the Model 3’s door when they had closed the app. There are still a few issues to be settled.įor example, CR testers found the Model 3’s virtual key doesn’t work unless the smartphone is turned on and the Tesla app is open and active. When the smartphone goes out of range and the system becomes disconnected, the doors are locked again.Nevertheless, it could be a few years before other automakers widely adopt the virtual key, if the results of a Consumer Reports test of the Model 3 are any indication. Once the smartphone comes into range and gets identified, the central locking system is activated. The receiver constantly searches for the mobile device’s MAC address which is programmed into the system. When the owner approaches carrying his or her smartphone equipped with Bluetooth, Model 3s can be set to unlock their doors and trunk automatically, and starting the Model 3 is as simple as shifting out of Park.īluetooth-based keyless systems use a smartphone’s Bluetooth connectivity instead of the conventional 315/434 MHz RF employed by ordinary key fobs. ![]() The first production vehicle to employ a Bluetooth (actually a BLE) digital key is Tesla’s Model 3. ![]()
