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 swing gate 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 on 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 illuminates 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

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 indi -
cated on the vehicle’s instrument cluster, and the fob
LED will no longer illuminate with a button press.

1. Remove the back cover of the fob by inserting a flat-blade screwdriver into the slot on the bottom of
the fob. Pry until the cover unsnaps being careful not
to damage the seal. Proceed counterclockwise to
pry the remaining snaps until the battery cover can
be removed.
1-3 – Back Cover Pry Points

2. Remove the depleted battery by inserting a small flat-blade screwdriver into the battery removal slot
and sliding the battery forward and up being careful
not to damage the electronic board underneath.

Battery Replacement

3. Install the new battery into the key fob, making sure the positive (+) side is facing up. Slide the battery
until it is seated securely below the tabs.
4. Reassemble the back cover making sure it is properly aligned before snapping it back in place.
WARNING!
The integrated key fob contains a coin cell battery.

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 swallowed or
placed inside any part of the body, seek immediate
medical attention.
 Keep new and used batteries away from children. If
the battery compartment does not close securely,
stop using the product and keep it away from chil -
dren.

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 elec -
tronics 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 autho -
rized 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.
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 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 381.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
If applicable, refer to the “Hybrid Supplement” for
additional information.
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, RUN, and START.
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™ Igni -
tion, always remember to place the ignition in the
OFF position when exiting the vehicle.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket Remote Start systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
