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.

REMOTE KEYLESS ENTRY FUNCTIONS
The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button and trunk open button.
System Diagram
Operation Description/Door Lock/Unlock Function
When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is sent from
Intelligent Key to Intelligent Key unit via remote keyless entry receiver.
Intelligent Key unit sends the door lock/unlock request signal to BCM via CAN communication line.
Intelligent Key unit sends the door lock/unlock signal to BCM.
When BCM receives the door lock/unlock signal, it operates door lock actuator, flashes the hazard lamp
(lock: 1 time, unlock: 2 times) and horn chirp signal to IPDM E/R at the same time as a reminder.
IPDM E/R honks horn (lock: 1 time) as a reminder
Operation Description/Trunk Open Function
When trunk button of the Intelligent Key is pressed, the trunk open signal is sent from the Intelligent Key to
the Intelligent Key unit via remote keyless entry receiver.
Intelligent Key unit sends trunk open request signal to BCM via CAN communication line.
When BCM receives the trunk open request signal, it operates the trunk lid opener actuator and opens the
trunk.
Operation Condition
Operation Area
Operating Range
To ensure the Intelligent Key works effectively, use within 100 cm range of each doors, however the oper-
able range might be differ by surroundings.
Selective Unlock Function
When an LOCK signal is sent from Intelligent Key, all doors will be locked.
When an UNLOCK signal is sent from Intelligent Key once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from Intelligent Key again within 5 seconds, all other door will be unlocked.

INTELLIGENT KEY SYSTEM
Revision: 2007 April2007 M35/M45
Hazard and Horn Reminder Function
When doors are locked or unlocked by Intelligent Key, Intelligent Key unit sends hazard and horn request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and sends horn chirp signal to IPDM E/R. IPDM E/R
sounds horn as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
Operating function of hazard and horn reminder
Hazard and horn reminder does not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-II
Hazard and horn reminder can be changed using “HORN WITH KEYLESS LOCK” and “HAZARD ANSWER
BACK” mode in “WORK SUPPORT”.Refer to BL-81, "
WORK SUPPORT" .
Without CONSULT-II
When LOCK and UNLOCK signals are sent from the Intelligent Key for more than 2 seconds at the same time,
the hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intel-
ligent Key is not inserted in key slot), doors are unlocked with Intelligent Key button. When Intelligent Key unit
does not receive the following signals within 30 seconds, all doors are locked.
Door switch is ON (door is opened)
Door is locked
Ignition switch is ON
Key switch is ON (Intelligent Key is inserted in key slot)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
81, "WORK SUPPORT" .
Panic Alarm Function
When ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intelligent Key is not
inserted in key slot), Intelligent Key unit receives PANIC ALARM signal from Intelligent Key.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM turns on and off headlamp intermittently and sends theft warning horn signal to IPDM E/R. Then, IPDM
E/R turns on and off horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:
After 25 seconds
When Intelligent Key unit receives any signal from Intelligent Key
When door request switch is pressed (Intelligent Key is within the outside key antenna detection area)
Panic alarm function mode can be changed by “PANIC ALARM DELAY” mode in “WORK SUPPORT”. Refer to
BL-81, "
WORK SUPPORT" .

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)
