Intelligent Key Battery ReplacementNIS001Y6
DISASSEMBLY AND ASSEMBLY OF INTELLIGENT KEY
1. Release the lock knob at the back of the Intelligent Key and remove the mechanical key.
2. Insert a flat-blade screwdriver (A) wrapped with a close into the
slit of the corner and twist it to separate the upper part from the
lower part.
CAUTION:

Be careful not to touch the circuit board or battery termi-
nal.

The key fob is water-resistant. However, if it does get wet,
immediately wipe it dry.
3. Replace the battery with new one.
4. Align the tips of the upper and lower parts, and then push them
together until it is securely closed.
CAUTION:

When replacing battery, be sure to keep dirt, grease, and
other foreign materials off the electrode contact area.

After replacing the battery, check to make sure all Intelli-
gent Key functions work normally.
INTELLIGENT KEY BATTERY INSPECTION
Check by connecting a resistance (approximately 300Ω) so that the
current value becomes about 10 mA.

INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
Revision: 2007 April2007 M35/M45
System DescriptionNIS001Y8

The engine start function of Intelligent Key system is a system that makes it possible to start and stop the
engine without removing the key. It verifies the electronic ID using two-way communications when press-
ing the push-button ignition switch while carrying the Intelligent Key, which operates based on the results
of electronic ID verification for Intelligent Key using two-way communications between the Intelligent Key
and the vehicle (Intelligent Key unit).
NOTE:
The driver should always carry the intelligent key at all times.

Intelligent Key has 2 IDs (for Intelligent Key and for immobilizer). It can perform the door lock/unlock oper-
ation and the push-button ignition switch operation when carrying the registered Intelligent Key.

When the Intelligent Key battery is discharged, it can be used as emergency by inserting the Intelligent
Key to the key slot. At that time, perform the immobilizer ID verification. If it is used when carrying the
Intelligent Key, perform the Intelligent Key ID verification.

If the ID is successfully verified, and when push-button ignition switch is pressed, steering lock will be
released and initiating the engine will be possible.

If the door lock/unlock operation is performed when the Intelligent Key battery is discharged, all doors
lock/unlock can be performed by operating the driver door key cylinder using the mechanical key set into
the Intelligent Key.

Intelligent Key can be registered up to 4 keys (Including the standard Intelligent Key) on request from the
owner.
NOTE:

Refer to BL-43, "INTELLIGENT KEY SYSTEM" for any functions other than engine start function of
Intelligent Key system.

Disarmed phase

When hood, doors or trunk is open, the vehicle security system is set in the disarmed phase on the
assumption that the owner is inside or near the vehicle.

When the vehicle security system is in the disarmed phase, the security indicator lamp blinks every 2.4
seconds.
Pre-armed phase and armed phase
When the following operation 1 or 2 is performed, the vehicle security system turns into the “pre-armed”
phase. (The security indicator lamp illuminates.)
1. BCM receives LOCK signal from front door key cylinder switch or Intelligent Key, after hood, trunk and all
doors are closed.
2. Hood, trunk and all doors are closed after front doors are locked by key or door lock and unlock switch.
The security indicator lamp illuminates for 30 seconds. Then, the system automatically shifts into the
“armed” phase.
Canceling the Set Vehicle Security System
When one of the following operations is performed, the armed phase is canceled.
1. Unlock the doors with the key or Intelligent Key.
2. Turn ignition switch “ON” or “ACC” position.
Canceling the Alarm Operation of the Vehicle Security System
When unlock the door with the key or Intelligent Key the alarm operation is canceled.
Activating the Alarm Operation of the Vehicle Security System
Make sure the system is in the armed phase. (The security indicator lamp brinks every 2.4 seconds.)
When the following operation 1 or 2 is performed, the system sounds the horns and flashes the headlamps for
about 50 seconds.
1. Hood, trunk or any door is opened during armed phase.
2. Disconnecting and connecting the battery connector before canceling armed phase.
