INTELLIGENT KEY SYSTEM
Revision: June 20062007 Versa
System DescriptionEIS0091W

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start function) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).

Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col-
umn to prevent accidental shut-off of the ignition switch and locking of the steering wheel during driving
condition when the vehicle is moving.
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 control 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 or unlocked with request switch or remote controller button operation, the haz-
ard lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).

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

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.

Operation Condition
If the following conditions are not satisfied, door lock/unlock operations are not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be 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 request switch (driver side, passenger side and back door area).
Hazard and Buzzer Reminder
When all doors are locked or unlocked by each request switch, Intelligent Key unit sends hazard request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer (driver door) as a reminder.
Operating function of hazard and buzzer reminder
Auto Door Lock Function
When all doors are locked, ignition knob switch is OFF (when ignition switch is not pressed) and key switch is
OFF (when mechanical key is out of ignition key cylinder), all doors are unlocked with each request switch.
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 lock signal from Intelligent Key button

Ignition knob switch is ON (ignition switch is pressed)

Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
11 3 , "WORK SUPPORT" .

Auto Door Lock Function
When all doors are locked, ignition knob switch is OFF (when ignition switch is not pressed) and key switch is
OFF (when mechanical key is out of ignition key cylinder), 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 knob switch is ON (ignition switch is pressed)

Key switch is ON (mechanical key is inserted in ignition switch)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
11 3 , "WORK SUPPORT" .
Panic Alarm Function
When ignition knob switch is OFF (ignition switch is not pressed), or key switch is OFF (mechanical key is not
inserted in key cylinder), by press and holding the panic alarm button on Intelligent Key will send a panic alarm
signal to Intelligent Key unit.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM sends headlamp request signal and horn signal to IPDM E/R. Then, IPDM E/R turns on and off head-
lamp and 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 remote controller of Intelligent Key

When door request switch is pressed (Intelligent Key is outside vehicle)
Panic alarm function's press and holding time value can be changed in “PANIC ALARM DELAY” mode in
“WORK SUPPORT”. Refer to BL-113, "
