INTELLIGENT KEY SYSTEM
Revision: 2006 December 2006 FX35/FX45
System DescriptionNIS001N6
The Intelligent Key system is a system which can lock and unlock the doors (door lock function) and start
the engine (engine start function) by carrying around the Intelligent Key, which operates based on the
results of electrical key-ID verification using two-way communications between the Intelligent Key and the
vehicle
Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote control entry system. (Remote control entry functions)
As an ignition key warning function, when a door is locked or unlocked with entry switch or remote control-
ler button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.
Even if the vehicle or Intelligent Key battery runs down, the door can be locked and unlocked and the
engine started with the mechanical key built into the Intelligent Key.
If an Intelligent Key was 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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK FUNCTION
Operation Description
When the driver door, passenger door, or back door request switch is pressed, Intelligent Key unit sends a
request signal from the transmission antenna corresponding to the pressed door request switch, key-ID
verification is performed using two-way communication with Intelligent Key, and if ID is successfully veri-
fied, a door lock/unlock request signal is sent to BCM (Body Control Module) using CAN communication
to lock/unlock the door lock.
When door is locking, door is unlocked, when door is unlocking, door is locked.
When door is locked/unlocked by door request switch operation, hazard lamps flash and Intelligent Key
warning buzzer sounds.
With the locking operation of door request switch, door lock actuators of all door are locked.

Refer to BL-116, "
WORK SUPPORT" .
Back door request switch operation
When back door request switch is pushed (unlock), back door lock actuator is unlocked.
When back door request switch is pushed (unlock) for the second time with in 5 seconds after the first
operation, door lock actuators on driver's and passenger's doors are unlocked.
Unlock mode can be changed using “WORK SUPPORT” mode in “SELECTIVE UNLOCK FUNCTION”.
Refer to BL-116, "
WORK SUPPORT" .
Operation Condition
Auto Door Lock Function
After the door request switch in the driver or passenger or back door is operated and the vehicle door is
unlocked, all the doors are automatically locked unless the mechanical key is inserted into the ignition knob,
the ignition knob is pressed, any door request switch is pressed, any one of the doors is opened, or an Intelli-
gent Key remote control button is operated within 30 seconds.
Key Reminder Function
The hazard lamps will flash and the Intelligent Key warning buzzer will sound several times when the door lock
is locked or unlocked by door request switch operation.
When ignition switch ON or any door is opened, key reminder function is not operate.
Intelligent Key Lock-in Prevention Function
When doors are locked using door lock and unlock switch or driver door lock knob while Intelligent key is in
vehicle and doors open, Intelligent Key unit sends door unlock request signal to BCM via CAN communication
to unlock all doors to prevent Intelligent Key from becoming locked in vehicle.
CAUTION:
The above function operates when the Intelligent Key is inside the vehicle. However, there are cases
that Intelligent Key cannot be detected and this function will not operate when Intelligent Key is on the
instrument panel, rear parcel shelf, or in the glove box. Also, this system sometimes does not operate
if the Intelligent Key is in the door pocket for the open door.
REMOTE CONTROL ENTRY FUNCTIONS
Door Lock Function
Operating a remote controller button on the Intelligent Key sends the Intelligent Key-ID to the Intelligent
Key unit. Intelligent Key unit conducts a verification of the received key-ID, and if the verification is

accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door.
When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION
Door lock/unlock operation is necessary for all doors close.
Map Lamp And Keyhole Illumination Function
When the following conditions come:
condition of map lamp switch is DOOR position;
door switch OFF (when all the doors are closed);
Remote control button of Intelligent Key turns on interior lamp (for 30 seconds) with input of UNLOCK signal
from Intelligent Key.
Panic Alarm Function
When key switch is OFF and ignition knob is not pushed (when mechanical key is not inserted in ignition
knob), BCM turns ON and OFF horn and headlamp intermittently with input of PANIC ALARM signal from
Intelligent Key. The alarm automatically turns off after 25 seconds or when Intelligent Key unit receives any
signal from Intelligent Key.
Panic alarm operation mode can be changed using “WORK SUPPORT” mode in “PANIC ALARM DELAY”.
Refer to BL-116, "
WORK SUPPORT" .
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with ignition switch OFF, and Intelligent Key unlock switch is
detected to be on continuously for 3 seconds, the driver's door and passenger's door power windows are
simultaneously opened.
Power window is operated to open and the operation continues as long as the Intelligent Key unlock switch is
pressed.
Remote control power window down operation mode can be changed using “P/W DOWN DELAY” mode in
“WORK SUPPORT”. Refer to BL-116, "
WORK SUPPORT" .
Key Reminder Function
As an operation verification function, when doors are locked or unlocked using Intelligent Key remote control-
ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description
When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID
verification is conducted with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)
When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights
up red.
When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses
CAN communication to send engine start permission signal to BCM.
When BCM receives engine start permission signal, it uses CAN communication to sent starter request
signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
