A parking point radio frequency receiving antenna is arranged near each parking place; a radiofrequency radio signal during parking can be read accurately; a car locating point radio frequency receiving antenna is arranged in a position such as a channel and an entry of the garage; when a carowner enters the garage, a car key sends the radio frequency radio signal; a way to a binding point can be showed accurately; and a car can be found. The system and the method have the beneficial effects that the radio frequency receiving antennae arranged in the garage receive the radio frequency radio signal of the car key; a car key identity and the signal sending position can be bound; the position can be quickly found by the radio frequency radio signal sent by the car key when the car owner looks for the car; an operation purpose of the car key each time can be quickly differentiated; binding and unbinding are performed in sequence; the target position of a parking and pick-up process each time is unique, so that quick and precise guidance is achieved; other equipment is not requiredto be worn; and the car owner can look for the car only by pressing any button on the car key.
