"BMW has announced an upgraded version of its mobile car key technology dubbed Digital Key Plus. It promises to allow iPhone owners to unlock select BMW cars without having to take out their phones. The feature relies on ultra wideband (UWB) which has been included in Apple’s flagship iPhones since the iPhone 11 thanks to the U1 chip. Digital Key Plus will debut on the all-electric BMW iX which launches later this year in Europe and next year in the US."
