Bluetooth key can drive the car away. For most car models, the vehicle can be driven away when started with one button even if the key is not in the car, but it cannot be restarted once turned off. As long as the car is started and the key is not inside, the vehicle can operate normally without turning off, but the dashboard will display a key warning. For those who often forget to bring keys, it is recommended to switch to fingerprint start, eliminating the need to carry keys. Below is an introduction to the car Bluetooth system: 1.
