GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB
Your vehicle is equipped with a key fob which
supports Passive Entry, Remote Keyless Entry
(RKE), Keyless Enter ‘n Go™ (if equipped), Remote
Start (if equipped), and remote power liftgate (if
equipped) operation. The key fob allows you to lock
or unlock all doors and liftgate, as well as activate
the Panic Alarm from distances up to
approximately 66 ft (20 m). The key fob does not need to be pointed at the vehicle to activate the
system. The key fob also contains an emergency
key, which is stored in the rear of the key fob.
NOTE:In vehicles equipped with Remote Start, the key
fob will operate at distances up to 328 ft (100 m).
NOTE:
The key fob’s wireless signal may be blocked if
the key fob is located next to a mobile phone,
laptop, or other electronic device. This may
result in poor performance.
If your vehicle is equipped with a Wireless
Charging Pad, the key fob may not be detected
if it is placed within 6 inches (15 cm) of the pad
Ú page 80.
With the ignition in the ON position and the
vehicle moving at 2 mph (4 km/h), all RKE
commands are disabled.

Key Fob
In case the ignition switch does not change
positions with the push of a button, the key fob
may have a low or fully depleted battery. A low key
fob battery can be verified by referring to the
instrument cluster, which will display directions to
follow.
For more information on ignition positions, see
Ú
page 22.
NOTE:A low key fob battery condition may be indicated by
a message in the instrument cluster display, or by
the LED light on the key fob. If the LED key fob light
no longer illuminates after a key fob button is
pushed, then the key fob battery requires
replacement Ú page 408.
To Lock/Unlock The Doors And Liftgate
Push and release the unlock button on the key fob
once to unlock the driver’s door, or twice within five
seconds to unlock all the doors and the liftgate. To
lock all the doors and the liftgate, push the lock
button once.
If enabled within the Uconnect system, the turn
signals will flash and other illuminated entry
features will be activated when the doors are
unlocked. When the doors are locked, the turn
signals will flash and the horn will chirp.

When the Vehicle Security system is armed, the
Vehicle Security Light (located in the lower right
portion of the instrument cluster display) will begin
to flash every two seconds until it is disarmed.
NOTE:If the system is armed by pushing the lock button
on the interior door panel, the Vehicle Security
Light will flash rapidly for about 15 seconds once
the door is closed, then slow down to every two
seconds.
TO DISARM THE SYSTEM
The Vehicle Security system can be disarmed using
any of the following methods:
Push the unlock button on the key fob.
Grab the Passive Entry door handle to unlock
the door Ú page 29.
Cycle the ignition out of the OFF position to
disarm the system.
NOTE:
The driver's door key cylinder cannot arm or
disarm the Vehicle Security system. Use of the
door key cylinder when the alarm is armed will
sound the alarm when the door is opened.
The Vehicle Security system remains armed
when the power liftgate is opened using the lift -
gate button on the key fob. If someone enters the vehicle through the opened liftgate, then
opens any door from the inside, the alarm will
sound.
If Passive Entry (if equipped) is used to unlock
the liftgate, the Vehicle Security system is
disarmed and the rest of the vehicle doors will
remain locked unless all doors are set to unlock
on first press within Uconnect Settings.
When the Vehicle Security system is armed, the
interior power door lock switches will not unlock
the doors.
The Vehicle Security system is designed to protect
your vehicle. However, you can create conditions
where the system will give you a false alarm. If one
of the previously described arming sequences has
occurred, the Vehicle Security system will arm
regardless of whether you are in the vehicle or not.
If you remain in the vehicle and open a door, the
alarm will sound. If this occurs, disarm the Vehicle
Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will flash,
and the horn will sound. If this occurs, disarm the
Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm and no action is
taken to disarm it, the Vehicle Security system will
turn the horn off after a 29 second cycle (with five
seconds between cycles and up to eight cycles if
the trigger remains active) and then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you lock
the doors using the emergency lock lever
Ú page 27.
TAMPER ALERT
If something has triggered the Vehicle Security
system in your absence, the horn will sound three
times and the exterior lights will blink three times
when you disarm the Vehicle Security system.
DOORS
MANUAL DOOR LOCKS
The front doors can be manually unlocked with a
single pull of the inside door handle. The driver’s
door can also be manually unlocked by inserting
the emergency key into the lock cylinder on the
outside door handle.

There are five situations that trigger a FOBIK-Safe
search in any Passive Entry vehicle:
A lock request is made by a valid Passive Entry
key fob while a door is open.
A lock request is made by the Passive Entry door
handle while a door is open.
A lock request is made by the door panel switch
while the door is open.
When the Vehicle Security system is in pre-arm
or armed status and the liftgate transitions from
opened to closed.
When the liftgate transitions from open to
closed and Remote Start is active.
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.
NOTE:The vehicle will only unlock the doors when a valid
Passive Entry key fob is detected inside the
vehicle. The vehicle will not unlock the doors when
any of the following conditions are true:
The doors are manually locked using the emer -
gency lock lever.
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 within 5 ft (1.5 m) of a Passive Entry
door handle.
To Lock The Vehicle’s Doors And Liftgate
With one of the vehicle’s Passive Entry key fobs
within 5 ft (1.5 m) of a Passive Entry door handle,
touch the lock icon on the door handle to lock all
four doors and liftgate.

Touch The Door Handle Lock Icon To Lock

NOTE:Do NOT grab the door handle when touching the
lock icon. This could unlock the door(s).
Do NOT Grab The Door Handle When Locking

NOTE:
After touching the door handle lock icon, you
must wait two seconds before you can lock or
unlock the doors using any Passive Entry door
handle. This is done to allow you to check if the
vehicle is locked by pulling the door handle,
without the vehicle unlocking.
If Passive Entry is disabled using the Uconnect
Settings, the key fob protection described in
"Frequency Operated Button Integrated Key
(FOBIK-Safe)" remains active/functional.
The Passive Entry system will not operate if the
key fob battery is depleted.
