Operation Description/Door Lock/Unlock

When the Intelligent Key unit detects that each door request switch is pressed, it starts the outside key antenna and inside key antenna corresponding to the pressed door request switch and sends the request signal to the Intelligent Key. And then, make sure that the Intelligent Key is near the door.
If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and sends the key ID signal to the Intelligent Key unit via remote keyless entry receiver.
Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
If the key ID check result is OK, the Intelligent Key unit sends the door lock/unlock request signal to BCM (Body control module) via CAN communication line.
Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key buzzer warning (lock: 1 time, unlock: 2 times) at the same time.
When BCM receives the door lock/unlock signal, it operates door lock actuator and flashes the hazard lamp (lock: 1 time, unlock: 2 times) at the same time as a reminder.
