Anti-theft Immobilizer: Security system that prevents the car from starting if the ignition key is not the correct one.
Read more
The anti-theft or immobilizing system is automatic and it begins working as soon as the key is inserted. If the key is not the right one, this system activates different blockages in the car to prevent it from starting. It blocks the injection system and that disables the entire ignition system of the car.
