new ID code is added and no ID codes are erased.
• Entry of maximum five ID codes is allowed. When mo re than five ID codes are entered, the oldest ID
code will be erased.
• Even if same ID code that is already in the memo ry is input, the same ID code can be entered. The
code is counted as an additional code.

Operation Description
• When the Intelligent Key unit detects that each request sw itch is pressed, it starts the outside key antenna
and inside key antenna corresponding to the pressed r equest switch and sends the request signal to the
Intelligent Key. And then, make sure that the Intelligent Key is near door.
• If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
sends the key ID signal to the Intelligent Key unit.
• 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 Ke y 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 warning buzzer (lock: 2 times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it oper ates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition If the following conditions are not satisfied, door lo ck/unlock operations are not performed even if the request
switch is operated.
