How Far Away Will the Car Automatically Shut Off When the Key Leaves?

[DiLucille]

Normally, when the key is within approximately 1 to 2 meters of the vehicle, the keyless control module will detect the presence of the key. Even without pressing the unlock button on the remote, you can enter the car by simply pressing the microswitch on the door handle. Once inside, the car's interior antenna will again verify the legitimacy of the key. After authentication, pressing the start switch will start the car, at which point the mission of the keyless anti-theft system is complete. Below is more related information: Smart Key System: A common car keyless entry system, also known as the smart key system, consists of a transmitter, a remote central locking control module, a driving authorization system control module (three receivers), and related wiring harnesses, forming a control system. The remote and transmitter are integrated into the car key. The vehicle can enter a locked or unlocked state based on the signals from the smart key and can even automatically close the windows and sunroof. Even if the key is lost, the car can still be driven, but the dashboard will display 'key not detected.' In such cases, once the car is turned off, it cannot be restarted, and the keyless anti-theft system will reactivate.
