What does the 'key' indicator on the Sylphy's dashboard mean?

[LeJuliette]

The KEY indicator on the Sylphy's dashboard means that the key is not detected. Here is the relevant information about the dashboard KEY: 1. This smart key can emit infrared signals, which can open one or two doors, the trunk, and the fuel filler cap, and can also operate the car's windows and sunroof. More advanced smart keys resemble a credit card. 2. When the driver touches the door handle, the central locking control system starts working and emits a wireless query signal. After the smart key card responds correctly, the car lock automatically opens. The engine will only start when the central processor detects that the key card is inside the car.
