What does the green key symbol mean on an instrument panel?

The green key symbol on an instrument panel typically indicates that the vehicle's ignition is in the "on" position and that the engine can be started. It may also signify that the vehicle's immobilizer system is functioning correctly, allowing the engine to run. If the symbol appears alongside other warning lights, it could indicate an issue with the key or the vehicle's security system. Always refer to the vehicle's owner's manual for specific meanings related to your model.
