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.

During Tesla’s Q1 earnings call, Tesla talked about its plan for its upcoming robotaxi network and even showed off a design for the app that would allow customers to request vehicles, much like Uber and Lyft.
While Tesla plans to unveil the robotaxi, officially now called CyberCab this August, a true autonomous taxi is at the very least, a couple of years away. So why is Tesla so eager to show off an app and start offering a Tesla taxi service?
in 2023 Uber had a revenue of 37.28 billion, while Lyft had a much smaller revenue of 4.4 billion. For comparison, Tesla’s revenue last year was 96.77 billion. A taxi service, even one operated by humans can be incredibly lucrative. While Tesla’s ultimate goal may be an automated taxi service, they may be itching to get into the space.
Tesla’s robotaxi was initially supposed to be a taxi service owners would lend their vehicles to. While that’s still the plan, Tesla wants their own vehicles to be a part of the service as well.
Will the Robotaxi Service Start With Tesla Drivers?
Tesla comparing themselves to Airbnb and Uber during their earnings call is intriguing. While Tesla can start producing robotaxis almost whenever they want, it’d likely be smart to wait until autonomy is solved so they’re not limiting themselves to current FSD hardware.
While full autonomy is likely several years away, Tesla seems to be eager to make this push toward a Tesla-owned service. Is Tesla thinking about operating their own Uber-like service? Tesla could be thinking about releasing their future robotaxi app and service in “beta,” letting current Tesla owners operate their own vehicles on the service.
This could result in several benefits for Tesla, not only letting them test their service but also opening up another revenue stream. This would allow Tesla to start operating their robotaxi network as soon as this year, and then slowly replace drivers and owner vehicles with Tesla-owned robotaxis.
Tesla Shows Off Robotaxi App

At the earnings call, Tesla also showed off a design of their robotaxi app. While it feels early to design an app for a service that could be years away, Tesla appears to be preparing itself for the future and getting customers excited about the prospect.
Tesla showed off five screens of the app, essentially showing how you’d request a robotaxi, how you can view its progress, and control certain features of the vehicle. Through the various screens, you can see most of Tesla’s Autopilot features coming to fruition in terms of autonomy, such as summon, self-driving and eventually Autopark.
Summon - Much like Tesla has re-thought the interior of a car and so many features, you can see the same mechanics applied to the app. To request a vehicle, you simply hold down a summon button and you’ll be presented with an estimate of when a vehicle will arrive.
Set Preferences and Destination - On the second screen, you can see the vehicle’s current location on a 3D map, possibly alluding to future FSD visualizations. It also lets you set your destination and set the climate temperature to your preference.
Trip Progress - While you’re traveling in the vehicle, you’ll be able to view trip information as well as set entertainment options.
Recap
Tesla had a lot to talk about during their earnings call and specifically about the Robotaxi — more information was revealed than ever before.
While there are various things at play to make a service like this come together, we can easily separate them out into separate components.
There’s the robotaxi itself, which Musk recently said would be similar to Tesla’s next-gen vehicle without a steering wheel. However, during this earnings call, he revealed that Tesla will save its new “unboxed” manufacturing process for the robotaxi and use a more traditional method for their next vehicle.
Then there’s FSD itself, while it’s crucial to operating a driverless robotaxi network, it’s not necessary to start a Tesla taxi service.
The last piece is the ride-hailing component itself and how it’s managed, and Tesla was happy to show this off, which makes us believe that it may be closer to reality than many think. While Tesla needs all three of these components to come together to operate a true robotaxi network, they piece them together separately, much like they’ve done with Autopilot. Initially, Tesla only released auto-steer then slowly added on summon, Autopark and city driving.
When we look back at Tesla five years from now, we may very well look back to this earnings call and say this was the pivotal moment when Tesla started transitioning to a services company.
Tesla has invested billions of dollars over the years toward vehicle autonomy. The mission continues as Elon Musk and Tesla now prepare to unveil their ride-hailing product, Robotaxi this August. Or, as Musk called it on Tuesday, Tesla CyberCab.
Early Days
Five years ago, during Tesla’s Autonomy Investor Day in April 2019, Elon Musk said he felt “very confident predicting autonomous robotaxis for Tesla in the following year [2020]”. At the time, Musk added a bolder claim, predicting that Tesla wouldn’t even make cars with steering wheels or pedals by 2022. While timeliness may not be Musk’s strong suit, he has a track record for getting things done that others were unwilling to try or thought were impossible. Musk later admitted he can be overly optimistic and said “sometimes I am not on time, but I get it done.”
Now, 5 years later, we have the robotaxi unveiling scheduled for August 8th. After the release of FSD v12, it’s clear that we’re much closer to autonomy than we were in 2019, although FSD v12 is still a far cry from full autonomy.
While Tesla still has the robotaxi unveiling scheduled for August, Tesla announced yesterday that it’d be prioritizing a simpler “next-gen” model that could be released by early 2025.
Latest Updates
On the conference call, Musk added that Tesla now has over 300 million miles driven with FSD v12 since it was launched just last month. He added that it's becoming “very clear that the vision-based approach with end-to-end neural networks is the right solution for scalable autonomy”.
Tesla said it has been investing in the hardware and software ecosystems necessary to achieve vehicle autonomy and a ride-hailing service. The company is confident that it can establish a scalable and profitable autonomous driving business by employing a vision-only architecture.

Tesla = Uber + AirBnb
Later on, Elon Musk unveiled that the new service will operate and result in a mix between Uber and Airbnb where the Tesla driver decides if and when he wants his Tesla to be used and by whom. Tesla stated:
“We believe the Tesla software experience is best-in-class across all our products, and plan to seamlessly layer ride-hailing into the Tesla App.”
Tesla’s CEO clarified that the owners will be able to add or remove their car from the fleet “whenever they want” adding that it will be up to them to decide if they want to only let the car be used “by friends and family or only by five-star users or by anyone at any time”. The flexible program will, just like Airbnb, allow the owners to take the car out of the market when they want.
The upcoming ride-hailing service will enable users to easily request a Tesla vehicle, control the car's temperature, monitor its real-time location, and adjust the audio system. The only question is when.
