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.

tabs.
4. Reassemble the back cover making sure it is properly aligned before snapping it back in
place.
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.
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.
Always remember to place the Keyless
Enter ‘n Go™ Ignition in the OFF position when
exiting the vehicle.2

23_JT_OM_EN_USC_t.book Page 17

18GETTING TO KNOW YOUR VEHICLE
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
ten 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 432.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
This feature allows the driver to operate the
ignition switch with the push of a START/STOP
ignition 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, 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 available.
ACC
Engine is not started.
Some electrical devices are available (power
windows, etc.).
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.

switch. This button comes as an assembly,
and is not removable. This can damage the
silicone shield.
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.
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 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.
