We remember that carkey is an API introduced with the first beta of iOS 13.4 that allows you to use a iPhone or an Apple Watch to open and close the doors of a car, but also to start it. The system designed by Apple can be used in all cars compatible with NFC systems: just keep the device close to the vehicle to use it as a real key. The car owner will not have to authenticate with the Face ID, but only need to have his iPhone near the car.

Users will then have to place the iPhone over the NFC reader in the passenger compartment during the initial process, after which CarKey will be available in the Wallet app. Subsequently, the key can also be added on Apple Watch.

CarKey can be shared with other people, for example with family members. Drivers can invite other people directly from the Wallet app, so as to enable access to the car on their iPhone and Apple Watch.

The digital car keys they can only be sent to other people through the Messages app. This sharing can only be done in private chats and not in group conversations.

Sharing a CarKey will allow that person to use their iPhone or Apple Watch to access a compatible car by keeping the device close to an NFC reader located inside the vehicle. Keys can be permanent (for a spouse, for example) or temporary (for a friend or mechanic).

People who receive a digital key through the Messages app will also see a text message which explains how to use this function:

[Proprietario del veicolo] has invited you to use his [Modello di veicolo] with unlock access and guide. This allows you to use iPhone and Apple Watch to unlock / lock the car, start the engine and drive.

Access to CarKey by people other than the car owner is biometrically authenticated using Face ID or Touch ID to make sure that the person holding the iPhone is the same authorized to access a car, although there is a “Express mode”Which supposedly should work without the need for authentication. There are no further details on this function.

Apple will work with auto manufacturers to popularize CarKey which, remember, requires an NFC module integrated into the vehicle. The company is also part of the Car Connectivity Concortium, which has announced a new standard for the creation of digital keys. called Digital Key Release 1.0, this technology aims to provide a single standard to all car and mobile device manufacturers in order to provide users with a single protocol for digital key.

The first compatible cars should be ready with the release of the public version of iOS 13.4.
