>Should not be impossible for a third party to replace a component Well, it's not. It's just hard. >if this would be legal for cars we would have been screwed even hard with replacement parts and fixes costs. I don't think you have worked with modern cars, situations like the Face ID issue here are perfectly normal. Try to do an engine swap in a new car, properly installing the engine does not get you a working car.

>Well, it's not. It's just hard. It seems to me that is is impossible, unless you argue that if I repair my device and Apple disables some features with DRM is just "hard" and is my fault I can't make the impossible and bypass the DRM.

  >Try to do an engine swap in a new car, properly installing the engine does not get you a working car. I am sure I don't need to send my Ford car to a Ford shop, third party services have the software needed to handle issues with CPU, maybe Tesla has some DRM and you need to go to an approved person.

    Yeah, often stolen dealership software isn't going to be enough for this stuff. Be prepared to spend your time dumping flash chips, reverse engineering and patching firmware.

      Really? what cars are already doing this? I don't drive a car but people in my family do(second hand Fords so no fancy expensive sport cars), and when they had issues(including replacing core engine stuff or electric stuff) the either bought some after market compatible part or went to the place where they scrap crashed cars and buy original parts from a destroyed car. It would suck if this cars for normal people will get DRMed to hell.

        I think every single new car from the past decade requires proprietary software to reset all the anti-theft features which would block you from changing the engine or ECU. Some manufacturers are more willing to share this software than others. I don't really know when exactly we're crossing the line where it becomes deliberate DRM instead of just poorly available proprietary software. The end result is the same. Another interesting situation is when you lose all of your car keys. Usually it's easy for your authorized repair shop to fix this, although they might need to have the manufacturer do it remotely(!). For independent shops it's not necessarily as easy as just plugging in a laptop, often they'll have to actually physically replace parts of the car in order to pair their new keys. Of course, there's a huge market for reverse engineering all this stuff so the indie shops continue to thrive despite many repairs now requiring extensive software reverse engineering.

  Even the article makes it clear that this repair is perfectly possible, just more difficult as you have to transplant a chip from one screen to another.
