3. Outline of Smart Key FOB Electronic Key is mainly used for locking or unlocking the doors of the vehicles. Electronic Key detects signals when it reaches the vicinity of vehicle, and sends signals using radio frequency. Also, Electronic Key sends a radio wave signal while a button is pushed. When the button is released, the radio wave signal is automatically off within 0.392 seconds. When the button is depressed continuously, Electronic Key sends a signal for a predetermined constant time. This product sends a signal when the following buttons are pushed. Transmitter IC Actuator Receiver Subject for application Installation in vehicle Micom Electronic Key Control IC LF Transmitter 314.35 MHz 134.2 kHz Smart Key ECU Trunk button for opening the trunk or back door. Lock button for locking the doors Unlock button for unlocking the doors.
