INTELLIGENT KEY SYSTEM

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verification using two-way communication between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
The settings for each function can be changed with CONSULT.
If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
It is possible to perform a diagnosis on the system and register an Intelligent Key with CONSULT.

DOOR LOCK FUNCTION

OPERATION DESCRIPTION

When the BCM detects that each door request switch is pressed, it activates the outside key antenna and inside key antenna corresponding to the pressed door request switch and transmits the request signal to the Intelligent 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 locks/unlocks each doors (except back door).
BCM sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) and blinks hazard warning lamps (lock: 2 times, unlock: 1 time) at the same time as a reminder.

OPERATION CONDITION

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

Lock	All doors are closed Panic alarm is not activated P position warning is not activated Intelligent Key is outside the vehicle Intelligent Key is within outside key antenna detection area *
Unlock	Panic alarm is not activated Intelligent Key is outside the vehicle Intelligent Key is within outside key antenna detection area *

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

OUTSIDE KEY ANTENNA DETECTION AREA

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) and back door handle (2). However, this operating range depends on the ambient conditions.
