What does it mean when the smart key is not in the car?

[LeAlexa]

The reasons why the smart key is not in the car are as follows: 1. If the display shows that the smart key is not in the car, it is most likely that the battery of the key is low. 2. Insufficient battery power prevents the radio waves from being received by the key's amplification coil, which triggers this prompt. 3. There is electromagnetic interference from signal towers or lights near the vehicle. If this happens, simply bring the key closer to the engine switch. Here is some extended information about smart keys: 1. Smart keys can emit infrared signals to open one or two doors, the trunk, and the fuel filler cap. They can also operate the car's windows and sunroof. 2. More advanced smart keys resemble a credit card. When the driver touches the door handle, the central locking control system activates and emits a wireless query signal. After the smart key card responds correctly, the car lock will automatically open. The engine will only start when the central processor detects that the key card is inside the car.
