OUTSIDE KEY ANTENNA

Description

INFOID:0000000005259943

Detects whether the Intelligent Key is in the operating range of the outside antennas.

Front outside antennas are integrated in front outside door handles (driver side, passenger side) to allow lock-

ing and unlocking of door locks when the Intelligent Key is present.

Rear bumper antenna is mounted on the rear bumper and is used to allow locking and unlocking of door locks

when the Intelligent Key is present.
