Frequency Operated Button Integrated Key
(FOBIK-Safe)
To minimize the possibility of unintentionally
locking a Passive Entry key fob inside your vehicle,
the Passive Entry system is equipped with an
automatic door unlock feature which will function if
the ignition is in the OFF position.
There are three situations that trigger a
FOBIK-Safe search in any Passive Entry vehicle.

1. A lock request is made by a valid Passive Entry key fob while a door is open.

2. A lock request is made by the Passive Entry door handle while a door is open.
3. A lock request is made by the door panel switch while the door is open. When any of these situations occur, after all open
doors are shut, the FOBIK-Safe search will be
executed. If it detects a Passive Entry key fob
inside the car, and it does not detect any Passive
Entry key fobs outside the car, the car will unlock
and alert the customer.NOTE:The vehicle will only unlock the doors when a valid
Passive Entry key fob is detected inside the
vehicle, and no valid Passive Entry key fob is
detected outside the vehicle. The vehicle will not
unlock the doors when any of the following condi
-
tions are true:
The doors are manually locked using the door
lock knobs.
Three attempts are made to lock the doors
using the door panel switch and then the doors
are closed.
There is a valid Passive Entry key fob outside the
vehicle and within 5 ft (1.5 m) of either Passive
Entry door handle. To Enter The Trunk:
With a Passive Entry key fob within 5 ft (1.5 m) of
the deck lid, push the button located on the center
of the light bar which is located on the deck lid
above the license plate.
