To give the correct secret answer to a question of the ECU you need the MB SKG Tool, which is able to calculate the correct answer. The unlocking challenges are kind of a question/answer game between ECU and diagnostic equipment. The Mercedes Benz Seed-Key Generator Tool (MB SKGT) was designed to unlock MB controllers in different levels to get access to critical diagnostic procedures and functions. ![]()
