INTELLIGENT KEY SYSTEM
Revision: 2006 July 2007 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.

When Any of the Following Conditions Are Met
When the ignition knob is pressed in so that it can be rotated (or has been rotated), if any
of the doors has been opened, when all the doors are closed, the Intelligent Key unit
compares the key-ID with that of the Intelligent Key using the inside key antenna, if the
results of the comparison are NG (the Intelligent Key is not found)
When the ignition knob is pressed in so that it can be rotated (or has been rotated), if any
of the doors is open, the Intelligent Key unit compares the key-ID with that of the Intelli-
gent Key every 5 seconds using the inside key antenna (center console), if the results of
the comparison are NG (the Intelligent Key is not found)
NOTE:
However, this warning is not issued if the mechanical key is inserted in the ignition knob.
Warning for take out of Intelligent
Key to outside the car (from win-
dow) When the ignition knob is pressed in so that it can be rotated (or has been rotated), if the
vehicle speed is no greater than 5 km per hour, the Intelligent Key unit compares the key-ID
with that of the Intelligent Key every 30 seconds using the inside key antenna, if the results
of the comparison are NG (the Intelligent Key is not found)
Note: The factory setting for this function is OFF.
Door lock non-operation warning When any of the following conditions are met
Intelligent Key Lock-in Prevention Warning
When the Intelligent Key is inside the car and the ignition knob is not pressed, when an
attempt is made to lock a door lock with a door request switch

CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II or Intelligent Key operation.
Changing Settings With the Intelligent Key
Intelligent Key remote controller button and door request switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure
1. With the ignition switch is in the LOCK position (ignition knob not pressed), hold down both the LOCK and UNLOCK remote control buttons on the Intelligent Key at the same time for at least 10 seconds (The yard-
stick is that the Intelligent Key LED flashes 20 times.)
2. Within 5 seconds of releasing the Intelligent Key remote controller buttons, press the driver door request switch.
3. The KEY warning lamp in combination meter lights up for 3 seconds (engine starting enabled → starting
disabled: lights up red, engine starting disabled → flashes green). This completes the settings change.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-116, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
Changing Settings Using Display Unit
The settings of the Intelligent Key system can be changed, using CONSULT-II, display unit, Intelligent Key and
door request switch in the center of the instrument panel.
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is executed using the CONSULT-II. Up to 4 can be registered.
CAUTION:
After a new Intelligent Key-ID is registered, be sure to check the function.
When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see the CONSULT-II Operation Manual NATS.
STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:
The method for registering a steering lock unit ID depends on the status of the steering lock unit
and Intelligent Key unit (new or old unit).
After registration is completed, press ignition knob with a portable unit in the vehicle so that it can
be rotated, and confirm that it cannot be rotated even when ignition switch is pressed without a
portable unit in the vehicle.
For further information, see the CONSULT-II Operation Manual NATS.
Setting item Description
