GETTING TO KNOW YOUR VEHICLE15
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 liftgate is
open, the doors will lock. The doors will unlock
again automatically if the key 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 within Uconnect Settings
Ú page 159.
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.

Key Fob Battery Replacement

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. Duplication of key fobs may be performed at an
authorized dealer. This procedure consists of
programming a blank key fob to the vehicle
electronics.
NOTE:
When having the Sentry Key Immobilizer system
serviced, bring all vehicle keys with you to an
authorized dealer.
Keys must be ordered to the correct key cut to
match the vehicle locks.
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.
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.

21_WD_OM_EN_USC_t.book Page 16

GETTING TO KNOW YOUR VEHICLE17
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 will shut the engine off in two seconds if an
incorrect key fob is used to start the engine.
After placing the ignition 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 used an invalid key fob to start the
engine. Either of these conditions will result in the
engine being shut off after two seconds.
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 327.
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 several
operating modes that are labeled and will
illuminate when in position. These modes are OFF,
ACC, ON/RUN, and START.

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. power locks,
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 position does not change with a push
of the ignition button, and the instrument cluster
display message “Key Fob Not Detected” is being
displayed, 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 of the key fob (side opposite of the emergency
key) against the START/STOP ignition button and
push to operate the ignition switch.
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.

Depleted Key Fob Battery Procedure

NOTE:
For more information on normal starting proce
-
dures, see Ú page 101.
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.
REMOTE START — IF EQUIPPED
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:Obstructions between the vehicle and key fob may
reduce this range Ú page 327.WARNING!
Before exiting a vehicle, always shift the auto -
matic transmission into PARK and apply the
parking brake. Always make sure the keyless
ignition is in the OFF position, remove the key
fob from the vehicle and lock the 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.
Children 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 ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ACC or 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. Always
remove the key fobs from vehicle, place the
ignition in the OFF position and lock all doors
when leaving the vehicle unattended.
WARNING!
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.
