What does the key light on the dashboard mean?

[LeHannah]

When the key warning light illuminates, it indicates an issue with the car's anti-theft system or the vehicle key. The most common cause is a depleted battery in the smart key, which requires replacing the key battery. Once successfully replaced, the key light issue will be resolved. However, if the key light remains illuminated after starting the engine, it suggests an engine fault that needs immediate attention at an auto repair shop using a diagnostic scanner to read the trouble code for repairs. Below is relevant information about car warning lights: 1. Seatbelt indicator: Shows whether the seatbelt is locked. When this light is on, it means the seatbelt hasn't been properly fastened. Some models may emit an audible reminder. The light turns off automatically when the seatbelt is properly fastened. 2. Door indicator: Displays the status of all vehicle doors. If any door isn't closed or isn't properly shut, the corresponding door indicator will light up to alert the driver. The indicator turns off when the door is properly closed.
