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), and
Remote Start (if equipped). The key fob allows you to
lock or unlock the doors and tailgate 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 a mechanical key.

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.
With the ignition in the ON/RUN position, and
the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.

Key Fob

NOTE:
In case the ignition switch does not change with
the push of a button, the key fob may have a low
or fully depleted battery. 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 illu-
minates from key fob button pushes, then the
key fob battery requires replacement.
Improper disposal of key fob batteries may be
harmful to the environment. Please see an
authorized dealer for proper battery disposal
Ú page 432.
WARNING!
Push the Mechanical Key Release Button only
with the key fob facing away from your body,
especially your eyes and objects that may be
damaged, such as clothing.
CAUTION!
The electrical components inside of the key fob
may be damaged if the key fob is subjected to
strong electrical shocks. In order to ensure
complete effectiveness of the electronic devices
inside of the key fob, avoid exposing the key fob
to direct sunlight.

16GETTING TO KNOW YOUR VEHICLE
To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key fob
once to unlock the driver’s door, or twice to unlock
all the doors. To lock all the doors, push the lock
button once.
When the doors are unlocked, the turn signals will
flash and the illuminated entry system will be
activated. When the doors are locked, the turn
signals will flash and the horn will chirp.
NOTE:
All doors can be programmed to unlock on the
first push of the unlock button through
Uconnect Settings Úpage 215.
The mechanical flip key can be used to lock or
unlock the doors, tailgate, glove compartment,
storage compartments (if equipped), and rear
seatbacks.
Key Left Vehicle Feature
If a valid key fob is no longer detected inside the
vehicle while the vehicle’s ignition system is in the
ON/RUN or START position, the message “Key Fob
Has Left The Vehicle” will be shown in the
instrument cluster display along with an interior
chime. An exterior audible and visual alert will also
be activated to warn the driver. The vehicle’s horn will rapidly chirp three times
along with a single flash of the vehicle’s exterior
lights.
NOTE:
The doors have to be open and then closed in
order for the vehicle to check for the presence of
a key fob; the Key Left Vehicle feature will not
activate until all of the doors are closed.
These alerts will not be activated in situations
where the vehicle’s engine is left running with
the key fob inside.
Replacing The Battery In The Key Fob
The recommended replacement battery is
CR2450.
NOTE:
Customers are recommended to use a battery
obtained from Mopar®. Aftermarket coin
battery dimensions may not meet the original
OEM coin battery dimensions.
Perchlorate material — special handling may
apply. See www.dtsc.ca.gov/hazardouswaste/
perchlorate for further information.
Do not touch the battery terminals that are on
the back housing or the printed circuit board.
When a key fob battery is low, a warning will be
indicated on the vehicle’s instrument cluster,
and the fob LED will no longer illuminate with a
button push.

1. Remove the back cover of the key fob by inserting a flat-blade screwdriver into the slot
on the bottom of the fob. Apply light pressure
until the cover unsnaps being careful not to
damage the seal. Proceed counterclockwise
(in the order shown in the following image) to
loosen the remaining snaps until the battery
cover can be removed.

20GETTING TO KNOW YOUR VEHICLE
NOTE:When opening the driver's door with the ignition in
the ON/RUN (engine not running) position, a chime
will sound to remind you to place the ignition in the
OFF position. In addition to the chime, the
message will display “Ignition Or Accessory On” in
the cluster.
REMOTE START — IF EQUIPPED
(GASOLINE)

This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
The system has a range of 328 ft (100 m).

Remote Start is used to defrost windows in cold
weather, and to reach a comfortable climate in all
ambient conditions before the driver enters the
vehicle.
NOTE:
The vehicle must be equipped with an auto -
matic transmission to be equipped with Remote
Start.
Obstructions between the vehicle and key fob
may reduce this range Ú page 432.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors and tailgate will lock, the turn signals will
flash twice, and the horn will chirp twice (if
equipped). Pushing the Remote Start button again
will shut the engine off.
NOTE:
With Remote Start, the engine will only run for
15 minutes.
Remote Start can only be used twice.
If an engine fault is present or fuel level is low,
the vehicle will start and then shut down in
10 seconds.
The parking lights will turn on and remain on
during Remote Start mode.
For security, power window operation is
disabled when the vehicle is in the Remote Start
mode.
The ignition must be placed in the ON/RUN posi -
tion before the Remote Start sequence can be
repeated for a third cycle.
All of the following conditions must be met before
the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not pressed)
Battery at an acceptable charge level
Panic button not pushed
System not disabled from previous Remote
Start event
CAUTION!
An unlocked vehicle is an invitation for thieves.
Always remove key fob from the vehicle and lock
all doors when leaving the vehicle unattended.
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas contains
carbon monoxide (CO) which is odorless and
colorless. Carbon monoxide is poisonous and
can cause serious injury or death when
inhaled.
Keep key fobs away from children. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.
