Apple Releases 'Car Keys Tests' App for Licensed MFi Developers

Apple has released a testing app for vehicle manufacturers who are working on integrating its digital Car Keys software (via 9to5Mac).

Apple's digital car key feature allows users to unlock and start a compatible vehicle by bringing an iPhone or Apple Watch near the driver-side door. The car keys are stored in the Wallet app, just like a credit card. The feature is currently limited to select BMW, Kia, and Genesis vehicles.

Called "Car Keys Tests," the new app allows licensed MFi developers to test and validate their own integration of the digital car keys technology, which Apple announced in July 2022.

Apple describes the developer tool in the following way:

For use by MFi Licensees only. Use the Car Keys Tests app to test and validate connection, performance, and other key requirements for the certification process of the vehicles you develop that incorporate Apple digital car keys technology.

"Car Keys Tests" isn't listed on the App Store, but there is a direct link to view and download the app. However, only developers with MFi licenses will be able to get past the login screen.

I no longer need to take my wallet, house keys or camera with me. Looking forward to the day I can dump the car keys as well. (oh, and California please hurry with that digital drivers license!)

Add to that the fact that many users, myself included, don’t trust Apple software and third party companies enough to secure things like houses and cars. I use Apple Wallet a lot but there’s a big difference in a bank card and a car for instance.
Your digital key is designed to be only operated by you. A physical key however can be operated by anybody. It (in theory) can’t be as non-secure as the key it’s replacing. But of course if you think that Apple can impersonate you and authorise another person to download your digital key, it’s totally another issue and you should throw away your smartphone at once since it’s much more dangerous than a key to your house.

Getting auto manufactures to do anything quickly is an ordeal. Remember the CarPlay roll out? I mean Tesla just added it like a few months ago.
Tesla didn’t add CarPlay. They did add Apple Music.

My issue is more to do with the p*ss poor reliability and stability of Apple’s software across the board, HomeKit being the most obvious example. I also wouldn’t want to rely on Apple software to power my car’s dashboard displays for the same reason.
