What does a car and a lock symbol displayed on the dashboard mean?

When a car and a lock symbol appear on the dashboard, it indicates that the vehicle's anti-theft system is activated. The primary function of the car anti-theft system is to prevent unauthorized individuals from stealing the vehicle using its own power, specifically by preventing illegal engine starts. The vehicle anti-theft system and the engine immobilizer system are essential for ensuring vehicle security. When the key is inserted into the ignition switch and turned to the 'ON' position, if the password verification is successful, the warning light will turn off, allowing the engine to start. If the password verification fails, the warning light will flash at a frequency of once every 2 seconds. When the vehicle is left unattended and locked, the electronic anti-theft system enters sleep mode, and the warning light will flash at a frequency of once every 5 seconds.
I've been driving for over twenty years and have seen this car lock icon several times. It means the anti-theft system is active, possibly because your key isn't being recognized by the vehicle. Common causes include a weak key battery or doors not fully closed triggering the alarm. Once I forgot to remove the key after parking, and it lit up - replacing the battery fixed it. This light is a security measure to prevent car theft. If the car operates normally when the light is on, immediate action may not be necessary; but if the car won't start, be cautious. I recommend developing the habit of checking key battery levels every six months to avoid roadside issues. Don't ignore minor anti-theft system glitches - have technicians check computer settings during regular maintenance.
