Further, the signal transmitted by the key contains an individual recognition code, and that code is registered to the car in advance. This accuracy is supported by technology that controls signal output with high accuracy and measuring technology that accurately detects key location. The technology in the Intelligent Key is characterized by its detection range accuracy for measuring keys. The signal transmitted by the car is tuned to reach an area one meter around the Request Switch, or when inside the car, only inside the cabin or trunk, so that only the person with the key in range can engage it. Similarly, for starting the engine, the ignition knob is turned or the engine start switch is pressed and the car transmits a signal, which is then received and returned by the key, and the engine activates. The car tuner receives this signal and then locks or unlocks the vehicle. Pressing the Request Switch transmits a signal from the car antenna, and the key that receives the signal then automatically returns a signal.
Intelligent Key utilizes antennae that transmit signals between the car and the key, and a tuner that receives the signals.
