I own Snapon diagnostic equipment capable of servicing anything up to 2016 model year and by extension a few more years unofficially if the model line continues.

It is very expensive but became reasonably priced after Snapon declared it unsupported and stopped making updates available.

The security excuse is not valid because there are many people like me who have electronics background, are willing to invest into right tools, and can fix anything but who have little desire to operate a shop.

My tool can reprogram keys, modify airbag parameters, troubleshoot anti-lock brakes and so on. All of that is safety systems.
