From physical key to smartphone, this is how Digital Key evolved and these are its models in Mexico

The relationship between the driver and the car key is changing. From metal, we moved to remote controls, then to cards and mobile apps, and now the smartphone can directly assume the functions of a key .

The Car Connectivity Consortium (CCC) , an organization that brings together car manufacturers, technology companies, smartphone developers, and component suppliers to establish connectivity standards, is involved in this transition .

One of its main developments is CCC Digital Key , a specification that defines how a digital key should function and how the vehicle and the user’s device can communicate. Its evolution has incorporated various wireless technologies, including NFC, Bluetooth Low Energy, and Ultra Wideband, which allows for more precise determination of the phone’s location relative to the car.

Evolution has also changed how the key is used. Early solutions were primarily associated with manufacturer-specific applications. With Digital Key, the CCC aims to establish a common architecture that allows the key to be stored on compatible devices , shared with others, and with different access permissions to be defined.

Examples of this transition can already be found in Mexico. BMW offers Digital Key in various models across its range, including the X1, X2, X3, X5, X6, X7, i4, i5, i7, and iX , although availability depends on the model year, equipment, and device used.

Kia also incorporated Digital Key 2.0 into the EV3 sold in Mexico . The system allows the use of a compatible smartphone as a key and combines different wireless technologies depending on the device used.

These cases are part of a much larger ecosystem. The CCC brings together companies that typically compete with each other but need to establish common rules so their technologies can work together. Its members include Apple, Google, Samsung, BMW, Ford, General Motors, Honda, Hyundai, Mercedes-Benz, Nissan, Toyota, Volkswagen, Kia, Mazda, Stellantis, Renault, Volvo, and Porsche .

Suppliers such as Bosch, Denso, NXP, and Qualcomm also participate , while Chinese manufacturers like Geely, BYD, NIO, XPeng, and Xiaomi are part of this ecosystem. Ceer , the new Saudi automotive brand, is also a Core member of the CCC .

The consortium’s role is not to manufacture a digital key, but to define the specifications and certification processes so that products developed by different companies can be compatible.

The evolution of Digital Key thus reflects a broader shift in the automotive industry . The key is no longer just an object, but has become a software function that forms part of the vehicle’s digital ecosystem.
