obtained from Mopar®. Aftermarket coin
battery dimensions may not meet the original
OEM coin battery dimensions.
Batteries contain harmful chemicals. Dispose
old batteries by placing them in correct
containers according to the law or by taking
them to a dealership, where they will be handled
appropriately.
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 by pushing the mechanical release button on the side of the
key fob with your thumb and then pulling the
key out with your other hand.

2. Insert a coin or a flat blade screw driver into the now exposed slot and carefully pry on both
sides to disengage the snaps. Gently remove
the back cover from the fob, being careful not
to damage any of the snaps.
3. Remove the battery by sliding the battery rearward in its pocket until the battery lifts up.
Remove the depleted battery from the battery
pocket and dispose appropriately.
4. Fit a new CR2032 battery ensuring that the positive (+) side is facing upwards. Push the
battery into the pocket until it is firmly seated
in place and secured under both tabs.
5. Align the back cover into its original position and snap it back in place by pushing it against
the fob until it is seated all around.

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.
KeySense Features — If Equipped
This feature provides the vehicle owner with the
ability to customize vehicle settings that can be
applied to determine the driving experience for
other drivers of the vehicle. The vehicle settings
are protected by a unique 4-digit PIN, which the
vehicle owner creates when accessing the specific
settings for the first time. KeySense also has additional features that are
always enabled when the specific key is in use that
cannot be set by the vehicle owner. While this
specific key fob is in use, the vehicle will respond
accordingly to the customized vehicle settings and
mandatory features. This includes enhanced
driving assistance features, increased driver
alerts, and the locking of certain optional features.
Settings can be customized within the Uconnect
system
Úpage 142.

KeySense Key Fob

KeySense Unique Splash Screen
At start-up the KeySense splash screen should
inform the driver that the vehicle will be
functioning in KeySense mode when the KeySense
key is in use.
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.
CAUTION!
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.

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.
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
Úpage 331.
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

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.

pedal)
The engine only runs in the ON/RUN ignition
position or from a Remote Start request.
In case the ignition switch does not change with
the push of a 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.
Backup Starting Method

NOTE:
The key fob may not be detected by the vehicle
Keyless Enter ‘n Go™ system if it is located next
to a mobile phone, laptop or other electronic
device; these devices may block the key fob’s
wireless signal and prevent the Keyless Enter ‘n
Go™ system from starting the vehicle.
For the proper engine starting procedure, see Úpage 106.
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).
WARNING!
When leaving 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.
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 Keyless Enter ‘n Go™ Ignition in
the 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 car is an invitation. Always remove
the key fobs from the vehicle and lock all doors
when leaving the vehicle unattended.
