Why don't the headlights turn on when locking the car?

[LaIsabel]

When the headlights don't turn on while locking the car, it's usually due to a sensor malfunction. First, check if the engine hood and trunk are properly closed. If they are confirmed to be closed, then you need to open the engine compartment to check if the rubber stoppers near the upper edges of both headlights are still in place. There's a sensor underneath where the rubber stopper should press down. The system only functions correctly when the rubber stopper properly presses on the sensor. Sometimes these stoppers might get accidentally removed during car washing. The car's remote locking system utilizes the wireless remote control function of the central locking system, allowing doors to be locked/unlocked without inserting the key into the lock cylinder. The working principle involves the key emitting weak radio waves, which are received by the car's antenna. The electronic control unit then identifies the signal code and activates the system's actuator to perform the locking/unlocking action.
