INTELLIGENT KEY SYSTEM

System DescriptionBIS000WZ

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (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 Intelli-
gent Key and the vehicle

Operation of the remote control buttons on the Intelligent Key also provides the same functions as the
remote keyless entry system. (Remote keyless entry functions)

As an ignition key warning function, when a door lock is locked or unlocked with request switch or remote
controller button operation, the hazard lamps flash and the Intelligent Key warning buzzer sounds.

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

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, change the function setting and register an Intelligent
Key with the CONSULT-II.
DOOR LOCK/UNLOCK, TRUNK OPEN FUNCTION
Operation Description

When the driver door, passenger door, or trunk open request switch is pressed, Intelligent Key unit sends
a request signal from the outside key antenna corresponding to the pressed request switch, key-ID verifi-
cation is performed using two-way communication with Intelligent Key, and if ID is successfully verified, a
door lock/unlock request signal is sent to BCM 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 lock 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 trunk open request switch is pushed, trunk lid is opened.
Operation Condition
Auto Door Lock Function
After the door request switch in the driver or passenger door is operated and the vehicle door locks are
unlocked, all the doors are automatically locked unless the mechanical key is inserted into the ignition knob,
the ignition knob is pressed, any door request switch is pressed, any one of the doors is opened, or an Intelli-
gent Key remote control button is operated within 2 minutes.
Hazard Reminder Function
The hazard lamps are flashed when the door lock is locked or unlocked by door request switch operation.
When ignition switch ON or any door is opened, key reminder function is not operate.
Request switch operation Operating conditions

Intelligent Key Lock-in Prevention Function
When Intelligent Key is in vehicle, a door is open, and doors are locked using door lock and unlock switch,
driver door lock knob, Intelligent Key unit sends door unlock request signal to BCM via CAN communication to
unlock all doors to prevent Intelligent Key from becoming locked in vehicle.
When Intelligent Key is in trunk room, all doors are lock and trunk lid is closed, Intelligent Key unit sends trunk
open signal to BCM. Then BCM open trunk lid and warning buzzer sounds for 10 seconds.
CAUTION:
The above function operates when the Intelligent Key is inside the vehicle. However, there may be
times when Intelligent Key cannot be detected and this function will not operate when Intelligent Key
is on the instrument panel, rear parcel shelf, or in the glove box. Also, this system some times does
not operate if the Intelligent Key is in the door pocket for the open door.
List of Operation Related Parts
Parts marked with × are the parts related to operation.
REMOTE KEYLESS ENTRY FUNCTIONS
Door Lock/Unlock Function

Operating a remote controller button on the Intelligent Key sends the Intelligent Key-ID to the Intelligent
Key unit. Intelligent Key unit conducts a verification of the received key-ID, and if the verification is
accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door lock.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
Trunk Open Function

Operating a remote controller button on the Intelligent Key sends the Intelligent Key-ID to the Intelligent
Key unit.

Intelligent Key unit conducts a verification of the received key-ID, and if the verification is accepted, a
trunk open request signal is sent to BCM via CAN communication trunk lid is opened.
