Tesla’s iPhone app gets better digital car key support with ultra wideband

The Tesla app now supports Ultra Wideband (UWB) in version 2024.2.3 of the iPhone app. Spotted by Not a Tesla app, It promises more reliable and secure use of phones as digital keys than Bluetooth, as UWB's precision tracking lets the car know exactly where the key is, which also helps protect it against hacker attacks. identity theft by proofreading.

The article says it even comes down to knowing which user is on the driver's side of the car in case two people with the car's phone keys get in. It's the same kind of precision tracking that lets you accurately locate Apple AirTags even when the object they're attached to is lost in your couch cushions.

The change isn't available to Android users yet, but some recent Pixel and Galaxy phones include UWB chips, so support may eventually come to them.

After downloading the update, users should be prompted to “Upgrade your phone key,” followed by a request to allow the app to access Nearby Interactions, an iOS setting that opens the chip U1 from iPhone to app. This can be found under Settings > Privacy & Security > Nearby Interactions.

According to Not a Tesla app, only the newer 2023 Model 3 and X support this feature, while the newer Model X and S and Cybertruck are expected to offer it across the board. All iPhones from 11 are equipped with UWB, excluding SE models.
