Getting started with Apple Car Key: Use your iPhone to start your car

Car Key enables you to unlock your car by simply by having your iPhone on your person.

Apple Car Key is a digital version of the physical key fob you use with your car, and was introduced with iOS 14 at WWDC 2020. It allows you to lock, unlock, and start your car from your iPhone or Apple Watch via NFC.

Why Car Key is useful

If nothing else, it means one less item to carry in your pockets - your car key. However, it also has other benefits.

In addition to NFC, Car Key makes use of the iPhone's U1 chip. This allows more precise spatial awareness, so it can unlock your car as you approach the door.

It also prevents your car from starting without your iPhone being inside, or you from locking your iPhone inside the car.

Your car key is cryptographically stored in the Secure Element and is viewable in your Apple Wallet. This means that, if your iPhone is lost or stolen, you can disable your car key remotely using iCloud.

And if you want to lend someone your car, you can also share a copy of the key via AirDrop or apps like Messages, Mail, and WhatsApp. Then you can revoke access at any time.
