Tesla has announced an update to its Phone Key feature, which integrates iPhone’s Ultra Wideband (UWB) technology to improve the performance of vehicle access. The update allows for more precise and responsive locking, unlocking, and automatic door operations. Users can upgrade their Phone Key through the Tesla app and switch from Bluetooth to UWB connectivity. This upgrade requires an iPhone 11 or later model with UWB and the latest Tesla app version. The feature is currently available for certain models, such as the Model 3 and the Cybertruck, and is exclusive to iPhone users. Tesla’s adoption of UWB technology for the Phone Key feature highlights the potential for further collaborations between automotive and smartphone technologies.
