Imagine never having to fumble for your car keys again—your iPhone or Apple Watch could soon be all you need to unlock and start your Cadillac. But here's where it gets exciting: Apple’s Car Key feature, which has been a game-changer for iPhone and Apple Watch users since 2020, is reportedly expanding to select Cadillac vehicles, according to newly discovered backend code. This means Cadillac drivers might soon join the growing list of car owners who can ditch traditional keys for a seamless, digital experience.
Here’s how it works: Using Near Field Communication (NFC), Apple’s Car Key allows drivers to lock, unlock, and start their vehicles directly from their iPhone or Apple Watch. The keys are securely stored in the Apple Wallet app, enabling users to access their cars simply by standing nearby or remotely. And this is the part most people miss—it’s not just about convenience; it’s also about security, as digital keys can be easily shared or revoked without the hassle of physical key replacements.
Currently, over 30 vehicle manufacturers support Apple’s Car Key functionality, and the list is growing. At WWDC 2025, Apple announced that 13 additional brands, including some under the General Motors (GM) umbrella, would soon adopt the feature. In October 2025, further evidence surfaced, hinting that GM-owned brands like Cadillac were on the verge of integration. Now, internal code suggests Cadillac, alongside Voyah and Smart vehicles, has been added to Apple’s Car Key-compatible list.
But here’s the controversial part: While the convenience is undeniable, some critics argue that relying solely on digital keys could pose risks if your device runs out of battery or gets lost. Others worry about potential security vulnerabilities in NFC technology. What do you think? Is the future of car keys digital, or are we moving too fast?
Cadillac’s adoption of Apple Car Key is a significant step forward, blending luxury with cutting-edge technology. However, it’s still unclear which Cadillac models will receive the feature first. As MacRumors notes, the integration is expected but not yet confirmed for specific vehicles. One thing’s for sure—this move could set a new standard for automotive convenience, leaving us to wonder: Are traditional car keys on their way out?
Thought-provoking question for you: Would you trust your iPhone or Apple Watch as your primary car key, or do you prefer the reliability of a physical key? Let us know in the comments—we’d love to hear your take on this evolving technology!
