Only when pressing the door request switch, it is possible to lock and unlock the door by carrying the Intelli-
gent Key.

OPERATION DESCRIPTION

• When the BCM 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 transmits the request signal to the Intelli-
gent Key. And then, check 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

transmits the key ID signal to the BCM via remote keyless entry receiver.

• BCM receives the key ID signal and compares it with the registered key ID.
• BCM lock/unlock each door (except back door) and sounds Intelligent Key buzzer warning (lock: 2 time,

unlock: 1 times) at the same time as a reminder.

OPERATION CONDITION

If the following conditions are satisfied, door lock/unlock operation is performed if the request switch is oper-
ated.

*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.
