This application relates to a vehicle unlocking and locking system, a passive radio frequency key, and a vehicle, to solve the technical problems of the passive radio frequency key relying on battery power, which leads to the inability to unlock the vehicle when the battery is depleted, and the risks of data leakage and vehicle theft associated with mobile APP keys. When the vehicle body controller is in the wake-up state, the UWB radio frequency unit sends a high-frequency ranging signal and receives a first response signal carrying authentication information returned by the key. The first response signal is generated by the key using energy segmented from the high-frequency ranging signal to process the information carried in the high-frequency ranging signal. The vehicle body controller calculates the distance between the key and the vehicle based on the time difference between signal transmission and reception. When the vehicle is in a partially dormant state, the vehicle body controller generates a vehicle unlocking command based on the distance and the key's authentication result. When the vehicle is in a fully awake state, the vehicle body controller generates a vehicle locking command based on the distance, the key's authentication result, and the vehicle's status information.
