To a vehicle equipped with an electronic anti-theft system (immobilizer*), additionally apply 3 code keys: 2 black - workers and 1 red - training.
* The immobilizer blocks the engine from starting without first reading the key code and thus provides additional protection for the car from unauthorized use. Remember that the APS system is only an additional barrier in the way of an intruder and does not provide absolute and complete protection of your car from unauthorized use.
