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.

Tesla Expected to Offer FSD Transfers in Europe

It has been a long wait for FSD for European customers, many of whom paid for the feature years ago on now legacy hardware. While the FSD transfer program has come and gone multiple times, there’s something to be said about having it available in North America, where it can be used, and in Europe or other countries, where it still just remains the same as Enhanced Autopilot (differences between Autopilot, EAP, and FSD).

FSD Transfer is a nice goodwill gesture from Tesla that in theory doesn’t cost them anything. Instead, it keeps customers, especially those who have been waiting for years, loyal and happy. It also incentivizes them to upgrade to a newer Tesla with HW4, where FSD will hopefully be achieved.

In a reply to a post on X, Elon agreed with the suggestion that offering FSD transfers in Europe would be a fair solution for those who have already purchased FSD but can’t use its capabilities.

Sounds fair

A Fair Solution

FSD Transfer directly addresses a growing concern for many long-term European Tesla owners. Thousands of customers purchased the full package, often many years ago, with the expectation that FSD would eventually be capable and approved for use. However, the reality is that FSD, even as an advanced driver assistance system (ADAS), continues to be pushed back in Europe.

As the regulatory process continues at a snail's pace, many of these early supporters are now reaching or have already passed the point where they’re ready to upgrade to a new Tesla.

Without the transfer program, it's a difficult choice: either throw away your original investment in FSD and pay for the package a second time (FSD price history), or subscribe to it in the future.

Offering FSD transfers is a good way for Tesla to meet them halfway. It's a difficult situation, and one that’s being hindered by processes beyond the control of both the customer and Tesla. However, a transfer helps both parties. Tesla sells another vehicle, and the customer gets to keep FSD.

When Will it Be Available?

Based on how FSD transfers have worked in the past following Elon’s announcements, this feature is likely to become available for a limited time period in the coming days or weeks. If it happens, we should expect an announcement from Tesla Europe on X and emails being sent out to Tesla customers.

Once the program is in place, all you need to do is complete your vehicle purchase and then inform your Tesla sales advisor that you’d like to transfer FSD. You don’t even have to sell or trade in your old Tesla; FSD will simply be removed from it as a feature.

Hopefully, Tesla enables FSD Transfers for everyone, regardless of region. It should be an ongoing offer until at least FSD is approved in the given country or region.

Tesla Increases Robotaxi Fare Fee, Up from $4.20

The introductory price for Tesla’s Robotaxi Network has finally been updated. In a post on X, Elon Musk confirmed that the new fare would be rolling out to complement the new Robotaxi geofence expansion.

This change marks the first adjustment to Tesla’s fares since the initial $4.20 launch price 23 days ago. While the price increase may seem significant in terms of percentages, when compared to other options in the ride-hailing area, it is still drastically cheaper.

But the price is now a princely $6.90, as foretold in the prophecy 😂

Context Matters

Robotaxi currently operates on a simple, flat-rate model. The new $6.90 fare gets you a ride to anywhere within the recently expanded geofence.

So far, this is the opposite approach compared to other services, such as Waymo or traditional ride-sharing options like Uber and Lyft. All these services use dynamic pricing based on distance, time of day, and demand. A comparable trip on any one of these services could cost anywhere from $30 to $65, and potentially even higher during peak hours.

That doesn’t even include the tip fees for human drivers either - another win for Robotaxi (can you tip a Robotaxi?).

Even with the adjustment, the flat $6.90 fare remains less than half the price of a typical competing ride, making Robotaxi the most affordable point-to-point transportation option in Austin, aside from mass transit, for now.

A “Maturing” Service

The price change, moving from one meme-worthy number to another, is a sign that Robotaxi is finally graduating from its initial pilot phase. Following the first major expansion of the service area, this adjustment is a logical next step towards finding a more sustainable flat price.

While the new fare is a 65% increase over the old fare, the key takeaway is that it is still far cheaper than other options, and still just as meme-worthy. Tesla is aiming to have its early access riders complete as many rides as possible during these early months, and this pricing is still very reflective of that.
