Samsung has announced partnerships with Audi, BMW, Ford, and Genesis to do just that, saying the feature may be available as soon as August 2021. And excitingly, those digital car keys should work with Apple iPhones and across other Android brands, too.
Samsung is part of multiple standards bodies that are working on the tech, including the Car Connectivity Consortium and the FiRa Consortium, of which Apple is also a leading member. “You’ll even be able to share your digital key across smartphones, regardless of brand or platform,” Samsung’s Kevin Chung announced during the company’s Galaxy S21 event today.
Unfortunately, it’s not yet clear which automakers will support the coolest, securest version of this tech: UWB. It uses small, standardized beacon-like pulses of low-power energy, preferably from multiple parts of your car at once, to figure out exactly where you are in relation to your car’s handle from a sizable distance away.
Samsung says with the new digital keys, “you’ll be able to unlock your car door when you reach it, no sooner, no later,” but I’m pretty sure it’s only referring to UWB there. The fallback is NFC, where you’d likely need to pull your phone out and tap it to your car, like you do with tap-to-pay NFC transactions today.
Samsung’s also introducing a UWB-based tracking tag for finding your lost gadgets later this year, though like the car keys it’s starting off with a less impressive Bluetooth version instead that won’t let you locate them as precisely.
