What is the flashing red light after locking the car?

[MatthewFitz]

Locking the car after a flashing red light is the anti-theft light, located at the angle where the front windshield meets the A-pillar. After the owner presses the lock button on the smart key, the car's anti-theft system is activated, and the anti-theft light will flash. Some anti-theft lights are red, while others are blue. Normally, the frequency of the engine anti-theft light flashing should be about once every 2 seconds. If this state persists, it means that the car's engine has entered the anti-theft state, and the engine anti-theft system is functioning. Introduction to the engine anti-theft system: The technology involves shutting down or deactivating all systems inside the car before unlocking. Even if someone forcibly starts the starter motor in the engine, the EF system will not inject fuel, and the ignition system will not work, preventing the thief from stealing the vehicle.
