Maybe not the other stuff, but I would probably not be surprised if Apple's car required an iPhone or Apple Watch to start. Now that they have NFC it probably isn't a battery issue as well.
I'd actually be surprised if it is the other way around. The only way to kill keys is to render them non-compliant.
