Car makers actually have the same thing. Not on bumpers, but on ignition keys and ECU (and possibly more). You can't swap out the ECU without getting keys reprogrammed by the dealer.
Specialized smaller shops also have the ability.
Currently there is NO WAY for me to change a screen on apple device without an annoying message or faceId issues on the 13. I cannot purchase a programming software.
Or some guy that figured it out with or without insider knowledge (which also usually means anyone can make a key for your car).
