Apple today announced Car Key, a way to wirelessly unlock your car with your iPhone, at its at Worldwide Developers Conference. The feature is part of the newly revealed iOS 14, and it will work over NFC, Apple says. The first car supported will be the new 2021 BMW 5 Series, which comes out next month, and Apple says its working on an industry-wide standard that would use its new U1 ultra wideband chip instead of relying solely on NFC.
Once you’ve paired your iPhone or Apple Watch with a car that supports Car Key, if you want to unlock your car, you’ll just need to hold your Apple device near an NFC reader that’s in your car (for example, in the car’s door handle)…
Car Key could be using the Car Connectivity Consortium’s Digital Key Release 2.0 specification, which was officially finalized in May.
