What does engine anti-theft authentication failure mean?

[HavenLee]

Engine anti-theft authentication failure is mostly caused by the following two reasons: 1. One is due to the matching problem between the remote key and the engine computer. There are many specific reasons: for example, electromagnetic interference nearby, large power equipment nearby, or in very open areas, etc. 2. The second is water ingress from the front windshield film (this reason is quite common), where water flows along the glass into the center console. Pay attention to this situation when applying the film, and it's best to place a towel on the dashboard. Content extension: With the above conditions, the symptoms are mostly brake failure, steering wheel becoming heavy, and failure to start the car. This is because the engine anti-theft system is activated, the car is cut off from fuel and power, cannot start, and thus there is no oil pressure, so the brake and power steering systems basically stop working.
