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 vehicle, the vehicle will unlock and alert
the customer.2
