Apple lays groundwork to use iPhone as a car key via NFC

Apple is seemingly taking the first steps to making an iPhone or Apple Watch function as a key for a car or van, with the presence of references to a CarKey API within the first iOS 13.4 beta indicating it could be used to unlock or even start a vehicle. In terms of what the CarKey API could do, it is thought its capabilities would include unlocking a vehicle, locking it, and starting the car.
