tion using two-way communications between the Intelligent Key and the vehicle (BCM).

key antenna corresponding to the pressed door request switch and transmits the request signal to the Intelli-

gent Key. And then, check that the Intelligent Key is near the door.

• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and

transmits the key ID signal to the BCM via remote keyless entry receiver.

• BCM receives the key ID signal and compares it with the registered key ID.
