iPhone Car Key Support Coming to Select Cadillac Vehicles

Monday November 17, 2025 3:44 pm PST by Juli Clover

Apple appears to be gearing up to add car key support to select Cadillac vehicles, based on backend code found by GeekWebGuides. Cadillac is now on an internal Apple list of vehicles that offer car key integration.

iPhone Car Key Kia

Apple has supported NFC-based digital keys in the Wallet app since 2022, and vehicle manufacturers have been adopting the feature since then. Digital keys allow users to lock, unlock, and start their vehicles with an iPhone or Apple Watch using NFC.

At WWDC 2025, Apple confirmed that 13 vehicle brands would "soon" add support for digital car keys, and Cadillac was on the list. Other brands included were Acura, Porsche, GMC, Chevrolet, Rivian, Smart, Lucid Motors, Tata Motors, Hongqi, WEY, Chery, and Voyah.

Apple has now added backend support for GM, Voyah, and Smart vehicles, but car manufacturers have yet to add support. For car key to come to Cadillac vehicles, GM will need to add the functionality.

GM has not yet provided details on which Cadillac models will support car key.

Some newer vehicles from BMW, Genesis, Kia, Audi, Hyundai, Lotus, Mercedes, Volvo, and more offer car keys support, with a list available on GeekWebGuides.com.

RIP, MacBook Ultra

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

I guess you've never had a valet park your car? What would happen in that situation? You'd have to give the valet your phone?

Tesla has Valet mode so they can drive your car without a key. I usually keep a keycard locked in the glovebox and give that to valet’s, mechanic’s etc.

Can someone explain to me why this is better than actually having a physical fob (or key) with you? I just see it as a solution in search of a problem.

I always have my phone, so not having to bring a car key means I can leave my house with just my phone. It’s not a couple of hundred to replace a digital car key or even Tesla’s keycard(€25 for 2). I can share temporary keys with friends or family. The devices that are being used to boost key fob signals from inside houses to unlock cars in their driveways don’t work on cars like Tesla that just use NFC and Bluetooth/UWB so they’re harder to steal.

What happens if your phone battery dies……🤔

It still works for a number of hours after your phone dies. To use the NFC chip uses a tiny bit of power which is held in reserve. It’s the one reason I want Tesla to implement it. Tesla’s app works fantastically well as a key, but if my phone dies then it won’t work.

It's so you don't have to carry the fob. For many people, carrying and keeping track of more things is not desirable, no matter how small and light--but also some key fobs are big and made of heavy steel for some dumb reason. There are also other advantages of digital like giving temporary keys to family or friends remotely. So the problems may not be huge for everyone, but they are there and significant for some.
