What does it mean when a car displays 'nokey'?

[DelJesse]

When a car displays 'nokey', it indicates that the key is not detected. This could be caused by several reasons: 1. The smart key is too far from the car's one-button start induction distance. 2. The smart key is out of battery. 3. The smart key is damaged. Below is more information about car keys: 1. Composition: The car smart key system, abbreviated as PKE, is a control system consisting of a transmitter, a remote central control module, a driving authorization system control module, three receivers, and related wiring harnesses. 2. Usage: When the key is near the car, the doors will automatically unlock and the anti-theft alarm will be deactivated, with corresponding light flashes to remind the owner that the car is unlocked. When the key moves a certain distance away from the car, the doors will automatically lock and the anti-theft alarm will be activated, with corresponding light flashes or a brief horn sound to remind the owner that the car is locked.
