What Causes the Red Light on the Car Key?

[JacksonFitz]

Here are the specific reasons why the car key shows a red light: 1. Normal phenomenon: Some car models, such as the Arrizo 5, will display a red light when the car key is pressed. 2. Accompanied by the car's failure to start and the dashboard not lighting up: If the car key shows a red light, along with the car not starting and the dashboard not lighting up, it is due to the car battery being dead. This might happen if the headlights were left on when locking the car, draining the battery. Replacing the battery will solve the problem. 3. Red backlight: It can be confirmed that the car key is stained with color. If the car key cannot be used normally, it is recommended to use the mechanical key to open the car first.
