System DescriptionNIS001X8

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), open the trunk (trunk open function), and start the engine (engine start function) by carry-
ing around the Intelligent Key (without some key operation), which operates based on the results of elec-
tronic ID verification using two-way communications between the Intelligent Key and the vehicle
(Intelligent Key unit).
CAUTION:
The driver should always carry the Intelligent Key

Operation of the remote controller buttons on the Intelligent Key also provides the same functions as the
remote controller entry system. (Remote keyless entry functions)

If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)

When a door lock is locked, unlocked or trunk open with request switch or remote controller button opera-
tion, the hazard lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/
horn reminder function).

Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked
with the mechanical key built into the Intelligent Key, and then initiates engine by inserting Intelligent Key
into key slot.

The settings for each function can be changed with the CONSULT-II.

If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can
be registered.

It has been made possible to diagnose the system and register an Intelligent Key with the CONSULT-II.
DOOR LOCK/UNLOCK/TRUNK OPEN FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door and open the trunk by carry-
ing around the Intelligent Key (without some key operation).
System Diagram
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.

INTELLIGENT KEY SYSTEM
Revision: 2007 April2007 M35/M45

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.
Operation Description/Trunk Open

When the Intelligent Key unit detects that trunk open request switch is pressed, it starts the outside key
antenna (trunk room) and inside key antenna corresponding to the pressed trunk open request switch and
sends the request signal to the Intelligent Key. And then, make sure that the Intelligent Key is near the
trunk.

If the Intelligent Key is within the outside key antenna (trunk room) 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 trunk open request signal to BCM (Body
control module) via CAN communication line.

Intelligent Key unit sends the trunk open request signal and sounds Intelligent Key warning buzzer 4 times
at the same time.

When BCM receives the trunk open request signal, it operates the trunk lid opener actuator and opens the
trunk.
Operation Condition
If the following conditions are not satisfied, door lock/unlock or trunk open operations are not performed even
if the request switch is operated.
*: Even with a registered Intelligent Key remain inside the vehicle, door locks can be unlock from outside of the vehicle with a spare Intel-
ligent 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 and passenger door handles (1). The outside key antenna
detection area of trunk open function is in the range of approximately
80 cm (31.50 in) surrounding Trunk opener request switch (2). How-
ever, this operating range depends on the ambient conditions.

Keyless Power Window Down (Open) Function
All power windows open when the unlock button on Intelligent Key is activated and kept pressed for more than
3 seconds with the ignition switch OFF. The windows keep opening if the unlock button is continuously
pressed.
The power window opening stops when the following operations are performed:

When the unlock button is kept pressed more than 15 seconds.

When the ignition switch is turned ON while the power window opening is operated.

When the unlock button is released.
While retained power operation activate, Keyless power window down (open) Function cannot be operated.
Keyless power window down operation mode can be changed by “P/W DOWN DELAY” mode in “WORK SUP-
PORT”. Refer to BL-81, "
WORK SUPPORT" .
Room Lamp Illumination Operation
When the following conditions are met:

Condition of interior lamp switch is in DOOR position

Door switch OFF (all the doors are closed)
Intelligent Key system turns on interior lamp (for 30 seconds) by receiving UNLOCK signal from Intelligent
Key. For detailed description, refer to LT- 2 6 9 , "
