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
conditions 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.
