Apple is taking part in a week-long industry test to measure how well the technology behind Car Key works in real life. The goal is simple. Make sure your iPhone and Apple Watch can unlock and start cars safely, reliably, and without friction.
The event brings together major carmakers and tech companies to test the digital key system under real conditions. This matters because more drivers now expect their phone to replace a physical car key. Apple wants its system to work across brands, not just on a few models.
A joint test of the digital key standard
The Car Connectivity Consortium runs the Plugfest to check how well different vehicles and devices work together. This year, the focus is on version 4 of the digital key standard, with added testing for version 3 to ensure backward compatibility.
BMW, General Motors, Hyundai, Mercedes, Rivian, and Volkswagen are part of the test. Other technology and testing firms are also involved. The aim is to find gaps early and fix them before new vehicles and devices reach customers.
The Car Connectivity Consortium said, “The event convenes leading automotive and technology companies for real-world interoperability testing of CCC Digital Key, the global standard for secure, smart device-based vehicle access.”
Digital car keys are no longer a niche feature. The group behind the standard says adoption has reached a tipping point.
The Car Connectivity Consortium stated that 2025 marked “an industry-wide turning point as digital keys move from early innovation to expectation.” It also reported that most of its member companies now see vehicle access as a core business priority.
Testing covers security, privacy, and reliability. That includes how well passive entry works. With this feature, your car unlocks automatically when you approach it with Car Key on your iPhone or Apple Watch, without tapping or opening an app.
iPhone and Apple Watch users
For you, this effort means fewer compatibility issues and stronger security across brands. As more vehicles adopt the standard, Apple’s Car Key feature should work more consistently, whether you drive a BMW, a Hyundai, or a Rivian.
The industry is pushing toward one shared system for digital keys. This week-long test is another step toward making your phone a trusted replacement for the key in your pocket.
