Why is the car lock icon flashing?

[MacKai]

The flashing car lock icon indicates that the anti-theft system is activated. This is the anti-theft system indicator light. It is normal for it to flash after locking the car. The car anti-theft system is designed to prevent the theft of the vehicle itself or items inside the car. The primary function of the car anti-theft system is to prevent unauthorized individuals from using the vehicle's own power to steal it, specifically by preventing illegal engine startup. The vehicle anti-theft system and the engine immobilizer system are essential for vehicle security, consisting of electronically controlled remotes or keys, electronic control circuits, alarm devices, and actuators. The engine anti-theft system automatically activates when the key is removed from the ignition switch or when the authorized electronic key is taken out of the vehicle. If the control indicator flashes when the ignition switch is turned on, it indicates a system malfunction, and the engine cannot be started. Turn off the ignition switch and try starting again. If the control indicator continues to flash, attempt to start the engine with a spare key. If the vehicle still cannot be started, contact a repair shop for assistance.
