DOOR REQUEST SWITCH OPERATION

When pressing the request switch, it is possible to lock and unlock the door by carrying the Intelligent 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 transmits door lock/unlock signal and operates each door lock actuator. At the same time, BCM blinks

hazard warning lamp (lock: 1 time, unlock: 2 times) and sounds Intelligent Key buzzer (lock: 1 time, unlock:

2 times) as a reminder.

OPERATION CONDITION

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

operated.

Remote keyless entry

Lock/unlock can be performed by pressing the remote controller button of the 
Intelligent Key

DLK-28

Key reminder

Warning

If an action that does not meet the operating condition of the Intelligent Key sys-
tem is taken, the buzzer sounds to inform the driver

DLK-31

*: 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.

Door lock function can be changed using “LOCK/UNLOCK BY I-KEY” mode in “WORK SUPPORT”. Refer to

DLK-36, "INTELLIGENT KEY : CONSULT Function (BCM - INTELLIGENT KEY)"

The outside key antenna detection area of door lock/unlock function

is in the range of approximately 80 cm (31.50 in) surrounding the

driver, passenger door handles (1). However, this operating range

depends on the ambient conditions.

HAZARD AND BUZZER REMINDER FUNCTION

For the operation check, BCM blinks hazard warning lamps (lock: 1 time, unlock: 2 times) and sounds Intelli-

gent Key warning buzzer (lock: 1 time, unlock: 2 times) when door lock or unlock operates by operation of

each door request switch.

How to Change Hazard and Buzzer Reminder Mode

Refer to 

DLK-36, "INTELLIGENT KEY : CONSULT Function (BCM - INTELLIGENT KEY)"

.

AUTO DOOR LOCK FUNCTION

After door is unlocked by door request switch operation and if 30 seconds or more passes without performing

the following operation, all doors are automatically locked. However, operation check function does not acti-

vate.

Auto door lock mode can be changed by the “AUTO LOCK SET” mode in “WORK SUPPORT”. Refer to
