[0062] When the user presses the start gear 7 of the electric door lock to trigger the ACC signal, the PKE controller will send a radio frequency of 125 kHz to the PKE host to search for the key. When the key is successfully verified, the control host will beep twice shortly, the turn signal will flash twice, the indicator light 10 of the unlocking signal switch will stay on for 5 seconds, and the unlocking signal will be output for 5 seconds.
