Apple today released the first beta version of iOS 13.4 for developers, and now 9to5Mac has found evidence of a new feature that will make it possible to use the iPhone as a car key, and more.

iOS 13.4 contains references to a “CarKey” API, which will make it possible to use the iPhone and also the Apple Watch to unlock, lock, and start a car. According to the system’s internal files, users will be able to use CarKey in NFC-compatible cars, as they only need to hold the device near the vehicle to use it as a key.

It will not be necessary to authenticate with Face ID, similar to what happens with Express Transit Cards. This also means that the feature will work even with iPhone or Apple Watch out of battery.
