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 all doors, tailgate, and the
RamBox (if equipped) as well as activate the
Panic Alarm 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 an emergency key, which is
stored in the rear of the key fob.
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.
If your vehicle is equipped with a Wireless
Charging Pad, the key fob may not be found if
it is placed within 15 cm (150 mm) of the pad
Ú page 77.
With the ignition in the ON position and the
vehicle moving at 2 mph (4 km/h), all RKE
commands are disabled.
Key Fob
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
can be verified by referring to the instrument
cluster, which will display directions to follow.
NOTE:
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.

18GETTING TO KNOW YOUR VEHICLE
To Lock/Unlock The Doors And Tailgate
Push and release the unlock button on the key
fob once to unlock the driver’s door, or, twice
within five seconds to unlock all doors, the
tailgate and the RamBox (if equipped). To lock all
the doors and the tailgate, push the lock button
once.
When the doors are unlocked, the turn signals
will flash and the illuminated entry system will
be activated. When the doors are locked, the
turn signals will flash and the horn will chirp.
All doors can be programmed to unlock on the
first push of the unlock button. The horn chirp
when the lock button is pushed can be
programmed on/off within Uconnect Settings
Úpage 237.
Air Suspension (Remote Lowering Of The
Vehicle) — If Equipped
For easy entry and loading, your
vehicle can be lowered by pushing the
key fob air suspension lowering button
two times. When air suspension
lowering is requested using the key fob, the
vehicle will send a series of chirps and flashes to
alert the customer that the operation has begun
and will continue these alerts until it successfully
lowers. The following conditions must be met for the
vehicle to lower remotely:
The vehicle must not already be in Entry/Exit
(Park) ride height.
The vehicle battery must be fully charged.
All doors must be closed.
The key fob must be out of the vehicle.
NOTE:
Ensure the vehicle is clear of all objects, pets,
and people prior to remote lowering.
Canceling Remote Lowering
Vehicle lowering can be cancelled at anytime.
When vehicle lowering is cancelled, the vehicle
will raise up to the next defined level and lock
out the remote lowering feature until the
ignition has been cycled ON/OFF.
To cancel vehicle lowering, push the key fob air
suspension lowering button one time during the
lowering process. When vehicle lowering is
cancelled, the horn will chirp two times and the
turn signal lamps will flash four times. Once
raising is completed, the horn will chirp one
time. NOTE:
More information on air suspension is provided
later in this manual Ú
page 165.
Replacing The Battery In The Key Fob
The replacement battery model is one CR2450
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 informa -
tion.
Do not touch the battery terminals that are
on the back housing or the printed circuit
board.
Do not replace the coin battery if the LED on
the key fob above the top row buttons blinks
when a button is pressed. The coin battery
should last a minimum of three years with
normal vehicle usage.

1. Remove the emergency key (1) by pushing
the emergency key release button (2) on
the side of the key fob, and pulling the
emergency key out with your other hand.
Emergency Key Removal
2. Hold the key fob with the button side facing down, and locate the small rectangular gap
on the left side between the housing and
the back cover of the key fob. Use a small
screw driver (or similar tool) to pry open the
left side of the fob cover while applying
pressure until the cover snaps open.
3. Next, locate the gap on the right side of the key fob, which is positioned further to the edge than the left side gap. Pry open the
right side, and remove the back cover.
4. Remove the battery by using your thumb to slide the battery downward and back
toward the key ring.
Key Fob Battery Location
NOTE:
When replacing the battery, ensure the (+) sign
on the battery is facing upward. Avoid touching
the new battery with your fingers. Skin oils may
cause battery deterioration. If you touch a
battery, clean it with rubbing alcohol.
5. Replace the battery by using your thumb to push down and slide the battery under the
small lip on the top edge of the opening.
Key Fob Battery Replacement
6. To assemble the key fob case, line up the top edge of the back cover with the top of
the fob, and press the edges into the
interlocking hinges until all edges snap
together with no large visual gaps.
7. Reinsert the emergency key until it locks into 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 re-purposed 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 Ú
page 482.
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 Ú
page 482.
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 mode.
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.
