What does engine anti-theft authentication failure mean?

[Felix]

Engine anti-theft authentication failure means that the car key is not detected. This situation mostly occurs because the car key has no power or there is a problem with the receiving module. When encountering this situation, the car owner should check the car key. The remote key of a car has a module specifically designed to start the engine. If the key has power but this module is damaged, the engine cannot be started. If the vehicle is equipped with a one-button start system, the engine can be started without inserting the key after getting into the car. Vehicles equipped with this system have a special position inside the car to sense the key. When the key has no power, the key can be placed in this sensing position to start the engine.
