Tesla is improving its phone key with ultra-wideband support

Maxim

In Tesla update 2024.2.3, Tesla is rolling out support for ultra-wideband, a wireless protocol that will drastically improve how Tesla phone keys work.

Ultra-wideband (UWB) requires hardware support on the user's phone and the vehicle, so only some of the most recent models will be supported.

What is Ultra-Wide

Ultra-wideband is similar to Bluetooth in that it uses short-range radio waves to enable devices to communicate, although it’s a separate protocol all together. It uses less energy than Bluetooth while providing high-precision location tracking beyond what can be achieved with Bluetooth. The technology is often used to accurately locate devices and determine the precise distance between multiple UWB devices.

Improved Phone Keys

Tesla phone keys are fantastic and give you a way to lock and unlock your vehicle without having to carry a key. They also let you share temporary or permanent keys with others without ever having to hand something over physically. It's one of the ways Tesla can now offer self-serve demo drives without any staff on hand.

While phone keys are great and work reliably most of the time, occasionally the car doesn't recognize that the phone is nearby, requiring you to take out your phone and unlock it or even open the Tesla app before it recognizes that the phone is nearby.

The addition of support for ultra-wideband should solve these issues almost completely by precisely knowing where the phone is in relation to the vehicle. UWB support is also expected to improve other features that rely on knowing your phone’s location, such as selecting the correct driver profile depending on which phone key is closest to the driver’s side.

Enabling UWB Phone Key

The new phone key won’t work out of the box. To use the improved UWB phone key, you’ll need to set it up in the Tesla app. The app will prompt you to “Upgrade Your Phone Key,” and you’ll then need to grant the app access to UWB, which the iPhones call Nearby Interactions. You can remove or check on whether the app has access at any time by navigating to iPhone Settings > Privacy & Security > Nearby Interactions.

Release Notes

Tesla states that its new feature "Ultra-Wideband Phone Key" will improve your phone key due to greater accuracy and better responsibleness.

The release notes read:

"Ultrawide band (UWB) technology is now available for Phone Key. So your vehicle and Phone Key can communicate with greater accuracy to more responsively lock, unlock, and open Automatic Doors.”

“In the Tesla app, choose Phone Key > Upgrade and follow the instructions. After setup, keep your iPhone Settings for Nearby Interactions on for Tesla. Requires iPhone 11+ and Tesla app 4.29.5+."

Cars Supported

Since ultra-wideband requires specific hardware, it can’t be added in a software update unless the hardware is already in the vehicle. Only some of the latest Tesla vehicles appear to support the new wireless protocol.

We have confirmed that the new Model 3 is supported, as well as the 2023 Model X. All refreshed Model S and Model X vehicles include the new UWB frequencies in the certificate of conformity and are likely to receive this feature, but it doesn’t appear to be going out to all new S/X models yet. The Cybertruck is expected to be supported as well.

The first-gen Model 3 and current Model Y unfortunately do not have UWB support.

Phones Support

In addition to the vehicle having support for UWB, the phone must also support it. All models since the iPhone 11 have included support for ultra-wideband. This spans across all models and sizes.

While some Android phones also include UWB hardware, Tesla is launching support for the iPhone first, but we can expect supported Android phones running Android 13 or later to be added at some point in the future as well.

On the Android side, the Pixel 6 and above have support for UWB on the Pro models, while the Galaxy S series phones support the protocol since the S21, but only on the Plus and Ultra models. The Galaxy Z Fold 2 and above also include support as well as other flagship Android phones.

Tesla App Support

Tesla started adding support for ultra-wideband back in July 2023 when Tesla updated their app to v4.23.5 and included references to ultra-wideband. Tesla says that you’ll require the latest Tesla app, v4.29.5 or higher to use the new feature.

Ultra wide-band will bring greater accuracy and reliability to Tesla's phone keys. The phone key is already great and the only thing holding it back is its ability to work reliably 100% of the time, but it looks like that is about to be fixed if you own a new Tesla model.

New Tesla Charging Visualizations Expected in the Future

October 10, 2024

Tesla’s Alex Guichet, Mobile App Engineer and Designer, posted on X that they are hiring a new C++ UI Engineer. According to Alex, this position will be focused on building the charging UI in Tesla vehicles.

While the charging UI received some basic updates back with the big Spring Update, it hasn’t really seen major changes in a long time. So, let’s take a look at what this position is exactly, and dig into what we’d like to see in the future.

Senior Software Engineer

The position that Tesla is hiring for is a Senior Software Engineer, Vehicle User Interface Charging – working out of Tesla’s Global Engineering Headquarters in Palo Alto, California. The position will be specifically responsible for the look and feel of the user charging experience, focusing on Tesla’s in-vehicle Infotainment UI.

Tesla expects the position to also work alongside business, product, engineering, and design teams to build simple, intuitive, and fluid user experiences.

That’s a broad job description, but Tesla pays well for what it offers – with the position starting at $120,000 a year, up to $210,000 a year. If you’re interested in the position, you can read more and apply here.

Charging Visualizations

Tesla’s current charging visualizations are fairly simple and to the point, both in the app and in the vehicle. Adding some flare to both visualizations would certainly be nice. If Tesla’s new parked visualization in AMD vehicles is any indication, we’re in for a treat with these upcoming visuals. Tesla could even add different visualizations depending on whether you’re charging with a Supercharger, Wall Connector, Mobile Charger, or a third-party charger.

Imagine if Tesla implements some of these visualizations directly into the vehicle’s visuals. You could pull up to a Supercharger and see them rendered directly on the screen and maybe even see how much each vehicle is charged, so you have a better idea of which stall will be available first.

We’d also love to see better and improved integration for Charge on Solar and PowerShare. There’s certainly a lot Tesla can do.

We’re excited to see the future of the charging UI but don’t expect these changes anytime soon since Tesla just started hiring for the position. However, it’s great to know where Tesla is headed and what they’re planning.
