Apple’s Car Key feature is expanding to Lexus vehicles, giving iPhone and Apple Watch owners the ability to unlock, lock, and start select Lexus models without a physical key fob. The addition makes Lexus the latest automaker to adopt Apple’s digital car key standard, joining a growing but still relatively small list of compatible brands.
The news, first reported by MacRumors, confirms that Lexus will support the Ultra Wideband (UWB) version of Car Key, which means you won’t even need to pull your phone out of your pocket. Just walk up to the car. It unlocks. Get in, press the start button, and drive. That’s the pitch, anyway — and in practice, UWB Car Key has worked reliably on supported BMW and other vehicles for a couple of years now.
Why This Matters for the Auto Industry
Lexus joining Apple Car Key is significant because it signals Toyota’s broader willingness to integrate with Apple’s protocols. Lexus is Toyota’s luxury division, and Toyota has historically been conservative about third-party tech integrations. The company was one of the last major automakers to adopt CarPlay, and it still doesn’t support Android Auto across its full lineup. So this move represents a genuine shift in posture.
Apple first introduced Car Key at WWDC 2020, initially partnering with BMW. Since then, adoption has been slow. BYD, Hyundai, Genesis, and Kia have added support in various markets, but the list remains shorter than you’d expect six years in. Adding Lexus — and by extension, signaling potential Toyota brand support down the line — could accelerate things.
The UWB implementation is the version worth caring about. Apple’s original NFC-based Car Key required you to hold your iPhone near a reader in the car’s door handle, which wasn’t much better than tapping a key card. UWB changes the equation entirely. It uses spatial awareness to detect your phone’s precise location relative to the car, enabling passive entry. No taps, no gestures. And it’s more secure against relay attacks than older Bluetooth-based keyless entry systems.
For Lexus owners, the practical upside is obvious: you can share a digital key with family members or friends directly through iMessage, set restrictions on speed or volume for younger drivers, and revoke access instantly. No more hiding a spare key in a magnetic box under the bumper.
The Technical Details
Apple Car Key is built on the Car Connectivity Consortium’s (CCC) Digital Key 3.0 specification, which standardizes UWB-based vehicle access across manufacturers. This isn’t a proprietary Apple protocol — it’s an industry standard that Google also supports for Android devices. But Apple’s implementation is currently more widely deployed on the automaker side.
Supported devices include iPhone models with a U1 or U2 chip (iPhone 11 and later) and Apple Watch Series 6 and later. The key is stored in the Secure Element on the device, the same hardware-level security used for Apple Pay transactions. Even if your iPhone dies, NFC-based Car Key still works with the device’s power reserve — a detail that matters more than most people realize until they’re standing in a parking garage with a dead phone.
Lexus hasn’t confirmed which specific models will get support first, though MacRumors indicates it will likely debut on 2026 model-year vehicles equipped with the brand’s latest multimedia system. Expect the NX, RX, and TX crossovers to be early candidates, given their sales volume.
And here’s where it gets interesting for fleet managers and enterprise buyers. Digital car keys can be managed remotely, provisioned and revoked without physical access to the vehicle. That’s a meaningful operational advantage for rental companies, corporate fleets, and car-sharing services. BMW has already leaned into this with its fleet partnerships, and Lexus entering the fold opens similar possibilities in the premium segment.
What’s Still Missing
Despite the progress, gaps remain. Android support for UWB car keys is still inconsistent across automakers. Google Wallet supports digital car keys for some vehicles, but the experience varies wildly depending on phone manufacturer and car brand. Apple’s tighter hardware-software integration gives it an edge here — for now.
There’s also no word on whether Toyota’s non-luxury models will follow. That would be the bigger story. Toyota sells roughly ten times the volume of Lexus globally, and bringing Car Key to the Corolla or RAV4 would put the feature in front of millions more drivers.
But for now, Lexus support is a solid step. One more brand. One fewer reason to carry a key fob. The slow march toward a phonecentric car experience continues.
