Most people don&#x27;t have the resources, knowledge, or desire to replace their car&#x27;s engine parts. Does that mean it&#x27;s ok to sell a car with a locked hood, that requires a manufacturer-controlled key before the engine can be serviced?<p>No, even if they personally don&#x27;t want to touch the engine, they turn to knowledgeable friends&#x2F;family or pay a professional mechanic to do the work.<p>This unfortunately-common view that most people should never even have the option to do anything technical is insulting and maybe even monopolistic (it bans 3rd party repairs&#x2F;parts).
