The Tesla app now supports ultra wideband (UWB) in the 2024.2.3 version of the app for iPhones. Spotted by Not a Tesla App<\/em><\/a>, <\/em>it promises more reliable and secure use of phones as digital keys than Bluetooth does because UWB\u2019s precision tracking lets the car know exactly where the key is, which also helps protect against replay spoofing attacks<\/a>. <\/p>\n<\/div>\n The article says this even comes down to knowing which user is on the driver\u2019s side of the car in the event that two people who have phone keys for the car are getting into it. It\u2019s the same type of precision tracking that lets you accurately locate Apple\u2019s AirTags<\/a> even when the thing they\u2019re attached to is lost in the cushions of your couch.<\/p>\n<\/div>\n The change isn\u2019t available for Android users yet, but some recent Pixel and Galaxy phones include UWB chips, so support could come to them eventually.<\/p>\n<\/div>\n After downloading the update, users should be prompted to \u201cUpgrade Your Phone Key,\u201d followed by a request to give the app access to Nearby Interactions, an iOS setting that opens up the iPhone\u2019s U1 chip to the app. That can be found under Settings > Privacy & Security > Nearby Interactions.<\/p>\n<\/div>\n According to Not a Tesla App, <\/em>only the newest Model 3 and 2023 Model X support the feature, while the newer Model X and S and Cybertruck should get it down the line. All iPhones from the 11 onward come with UWB, excluding SE models<\/a>.<\/p>\n<\/div>\n
