14GETTING TO KNOW YOUR VEHICLE
NOTE:
If the vehicle is unlocked with the key fob, and
no door is opened within 60 seconds, the
vehicle will relock and the security system will
arm (if equipped).
If one or more doors are open, or the trunk is
open, the doors will lock. The doors will unlock
automatically if the key fob is left inside the
passenger compartment, otherwise the doors
will stay locked.
All doors can be programmed to unlock on the first
push of the unlock button through Uconnect
Settings Ú page 125.
To Unlatch The Trunk
Push the trunk button on the key fob two times
within five seconds to unlatch the trunk.
Replacing The Battery In The Key Fob
The recommended replacement battery is one
CR2032 battery.
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/hazard -
ouswaste/perchlorate for further information.
Do not touch the battery terminals that are on
the back housing or the printed circuit board.

1. Remove the emergency key (2) by sliding the emergency key release (1) on the back of the
key fob and pulling the emergency key out
with your other hand.

Emergency Key Removal
2. Separate the key fob halves using a #2 flat
blade screwdriver or a coin, and gently pry the
two halves of the key fob apart. Make sure not
to damage the seal during removal.

3. Remove the back cover to access and replace the battery. When replacing the battery, match
the (+) sign on the battery to the (+) sign on the
inside of the battery clip, located on the back
cover. Avoid touching the new battery with your
fingers. Skin oils may cause battery deterio -
ration. If you touch a battery, clean it with
rubbing alcohol.
4. To assemble the key fob case, snap the two halves together.
Programming And Requesting Additional
Key Fobs
Programming the key fob may be performed by an
authorized dealer.
NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
Only key fobs that are programmed to the
vehicle electronics can be used to start and
operate the vehicle. Once a key fob is
programmed to a vehicle, it cannot be
programmed to any other vehicle.
Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics. A blank key fob is one that has
never been programmed.
NOTE:When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.
SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling the
engine. The system does not need to be armed or
activated. Operation is automatic, regardless of
whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button
ignition and a Radio Frequency (RF) receiver to
prevent unauthorized vehicle operation. Therefore,
only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The
system cannot reprogram a key fob obtained from
another vehicle.
After placing the ignition switch in the ON/RUN
position, the Vehicle Security Light will turn on for
three seconds for a bulb check. If the light remains
on after the bulb check, it indicates that there is a
problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates
that someone attempted to start the engine with
an invalid key fob. In the event that a valid key fob
is used to start the engine but there is an issue
with the vehicle electronics, the engine will start
and shut off after two seconds.
WARNING!
The integrated key fob contains a coin cell
battery. Do not ingest the battery; there is a
chemical burn hazard. If the coin cell battery is
swallowed, it can cause severe internal burns
in just two hours and can lead to death.
If you think a battery may have been swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from chil -
dren. If the battery compartment does not
close securely, stop using the product and
keep it away from children.
WARNING!
Always remove the key fobs from the vehicle
and lock all doors when leaving the vehicle
unattended.

For vehicles equipped with Keyless Enter ‘n Go™
Ignition, always remember to place the ignition in
the OFF position.

16GETTING TO KNOW YOUR VEHICLE

If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than
10 seconds), it indicates that there is a fault in the
electronics. Should this occur, have the vehicle
serviced as soon as possible by an authorized
dealer.

All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú page 305.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button as long as
the key fob is in the passenger compartment.
The START/STOP ignition button has four
operating positions, three of which are labeled and
will illuminate when in position. The three positions
are OFF, ACC, and ON/RUN. The fourth position is
START. During START, RUN will illuminate.
START/STOP Ignition Button

The push button ignition can be placed in the
following modes:
OFF
The engine is stopped.
Some electrical devices (e.g. central locking,
alarm, etc.) are still available.
ACC
Engine is not started.
Some electrical devices are available (e.g.
power windows). ON/RUN

Driving position.
All electrical devices are available (e.g. climate
controls, etc.).
START
The engine will start (when foot is on the brake
pedal).
NOTE:
If the ignition switch does not change the mode by
pushing the button, the key fob may have a low or
depleted battery. In this situation, a back up method
can be used to operate the ignition switch. Put the
nose side (side opposite of the emergency key) of
the key fob against the START/STOP ignition button
and push to operate the ignition switch.
Depleted Key Fob Battery Procedure

CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.
1 — OFF
2 — ACC
3 — ON/RUN

21_LD_OM_EN_USC_t.book Page 16

GETTING TO KNOW YOUR VEHICLE17
NOTE:
When opening the driver's door with the ignition
in ON/RUN (engine not running), 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.
For more information on proper engine starting
procedures, see Úpage 83.
REMOTE START — IF EQUIPPED
This system uses the key fob to start the
engine conveniently from outside the
vehicle while still maintaining security.
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:Obstructions between the vehicle and key fob may
reduce this range Ú page 305.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The vehicle
doors will lock, the parking lights will flash, and the
horn will chirp twice (if programmed). Then, the
engine will start, and the vehicle will remain in the
Remote Start mode for a 15 minute cycle. Pushing
the Remote Start button a third time shuts the
engine off.
To drive the vehicle, push the unlock button, and
with a valid Keyless Enter ‘n Go™ key fob in the
vehicle, press the brake pedal and place the
ignition in the ON/RUN position.
WARNING!
When exiting the vehicle, always remove the
key fob from the vehicle and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle.

Allowing children to be in a vehicle unattended
is dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil -
dren should be warned not to touch the parking
brake, brake pedal or the gear selector.

Do not leave the key fob in or near the vehicle, or
in a location accessible to children, and do not
leave the Keyless Enter ‘n Go™ Ignition in the
ON/RUN position. A child could operate power
windows, other controls, or move the vehicle.

Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
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.
