REMOTE KEYLESS ENTRY SYSTEM
Revision: June 20062007 Versa
NOTE:

If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not known, all con-
troller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new
keyfobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.

When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

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.

ENGINE START FUNCTION
When the registered Intelligent Key is carried, the engine can be started without inserting the key.
When ignition knob switch is ON (press ignition switch), Intelligent Key unit searches Intelligent Key in the
vehicle using inside key antenna.
Then Intelligent Key is inside the vehicle, it performs the following operation.

Illuminate green “KEY” warning lamp in combination meter.

Released steering lock and ignition switch can be turned from OFF to ACC, ON or START position.
NOTE:
If Intelligent Key is not registered, “KEY” warning lamp in combination meter illuminates red.

Intelligent Key sends engine start signal to BCM via CAN communication line.
When ignition switch turns to START position, BCM sends starter request signal to IPDM E/R. Then, engine
starts.
Even if Intelligent Key battery runs down, Intelligent key unit can start engine with mechanical key built Intelli-
gent Key. For details, refer toBL-212, "
NATS (Nissan Anti-Theft System)" .
All of the originally supplied Intelligent Key IDs (except for key) have been registered in Intelligent Key system.
If requested by the vehicle owner, a maximum of four Intelligent Key IDs can be registered into the Intelligent
Key system components.

CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-113, "
WORK SUPPORT" .
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 performed using the CONSULT-II.
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 further information, see the CONSULT-II Operation Manual NATS.
STEERING LOCK SOLENOID REGISTRATION
Steering Lock Solenoid ID Registration
CAUTION:

The method for registering a steering lock solenoid ID depends on the status of the steering lock
solenoid and Intelligent Key unit (new or old unit).

After registration is completed, press ignition switch with an Intelligent Key in the vehicle so that it
can be turned, and confirm that it cannot be turned even when ignition switch is pressed without
an Intelligent Key in the vehicle.
For further information, see the CONSULT-II Operation Manual NATS-IVIS/NVIS.
