List of Operation Related Parts
Parts marked with × are the parts related to operation
REMOTE KEYLESS ENTRY FUNCTIONS
The Intelligent Key has the same functions as the remote keyless entry system. Therefore, it can be used in
the same manner as the keyfob by operating the door lock/unlock button.
System Diagram
Door Lock/Unlock Function

When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is sent from
Intelligent Key to Intelligent Key unit.

Intelligent Key unit sends the door lock/unlock request signal to BCM via CAN communication line.

Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key warning buzzer (lock: 2
times, unlock: 1 time) at the same time.

When BCM receives the door lock/unlock signal, it operates door lock actuator and flashes the hazard
warning lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
Hazard and Buzzer Reminder
When all doors are locked or unlocked by Intelligent Key button, Intelligent Key unit sends hazard request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer as a reminder.
