    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.
