It goes like this - in eastern europe and other funny places there was no dealer network for cars and so no service. If you lost a key or similar someone needed to fix it. At first it was quite simple. Read eeprom, change eeprom etc. This industry developed over a number of years as did the skills. If you have no other option for being employed as an electrical engineer this is probably quite ok. Later as markets opened up and the internet became a thing the tools found an international outlet. First auto locksmiths, then thieves stealing to ship abroad (africa etc) and then drug dealers who had and would pay big money to access cars that are used for hits and other work. So it continues. The latest high end cars have real encryption onboard with unique keys. Taking them is much harder...
