What does it mean when the red key indicator light is on?

[GriffinDella]

There are two types of red flashing key indicators on the dashboard. One without the KEY symbol is the engine immobilizer indicator light, which normally turns off after the car is started. If it does not turn off, it may indicate a fault in the anti-theft system, and you should have it checked at a 4S shop or auto repair shop. The other type with the KEY symbol indicates low battery in the car key. You should promptly check and determine whether the battery needs to be replaced. Once the battery is low, it should be replaced as soon as possible to avoid inconvenience in using the car. Car Anti-Theft System: The function of the car anti-theft system is to prevent the car itself from being stolen and to protect valuable items inside the car. The car anti-theft system mainly consists of electronic control circuits, alarm devices, remote keys, mechanical keys, and actuators. Mechanical door locks are responsible for preventing the doors from opening automatically while the car is in motion but cannot serve as an anti-theft measure. The anti-theft system adds a steering lock, which locks the car's steering column. Both the steering lock and ignition lock are located below the steering wheel.
