    You don’t have to have paired parts for secure authentication. You just need parts that have been set up and authenticated beforehand. That is not the same as part pairing.

      What’s to stop me from going to a junk yard, paying for a key and the modules in question, attaching them to a different car and stealing that car?

        Literally nothing stops you from doing that with paired parts. Nothing. Keyless cars get hacked, stolen, dismantled, and rebuilt all the time, just like any other car.

        Encryption and authentication are equally secure with or without physical part pairing.

          That’s not true. The paired parts are attached to the VIN. Literally programmed with the VIN of the car and a lot of them are single use for specifically this reason. You don’t know and you’re very insistent.

            You can get whatever paired modules with a paired key from a wrecked car and plug them into a different car and start it.

              You can’t. That’s the point. Once those parts are configured to a vin they only work with that vin.

            I guarantee you that the paired parts can and will be swapped out or stolen. It does nothing to protect consumers. Give me an example of a manufacturer who uses paired parts and I’ll find examples of thefts, hacks, and replacements.
