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), Remote
Start (if equipped), and remote trunk release. The
key fob allows you to lock or unlock the doors and
trunk from distances up to approximately 66
ft
( 2

0 m). The key fob does not need to be pointed at
t h
e 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.
With ignition in the ON position and the vehicle
moving at 2 mph (4 km/h), all RKE commands
a r
e disabled.

Key Fob
In case the ignition switch does not change with
t
h

e 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
Ú page 254.
To Lock/Unlock The Doors And Trunk
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 the doors and the trunk. To
lock all the doors and the trunk, push the lock
button once.
When the doors are unlocked, the turn signals will
fl

ash and the illuminated entry system will be
activated. When the doors are locked, the turn
signals will flash and the horn will chirp.

GETTING TO KNOW YOUR VEHICLE 13
NOTE:
If the vehicle is unlocked by Passive Entry 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 trunk is
open, the doors will lock. The doors will unlock
automatically if the key fob is left inside the
passenger compartment, otherwise the doors
will stay locked.
All doors can be programmed to unlock on the first
p u

sh of the unlock button through Uconnect
Settings
Ú page 122.
NOTE:
When you use the key fob to open any door, the
c ou
rtesy lights, overhead lights, and approach
lighting in the outside mirrors (if equipped) will turn
on
Ú page 43.
To Unlatch The Trunk
Push the trunk button on the key fob two times
within five seconds to unlatch the trunk.
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/hazardouswaste/
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 e
mergency key release (1) on the back of the
key fob and pulling the emergency key out
with your other hand.

Emergency Key Removal
2. S
eparate the key fob halves using a #2 flat
b
lade screwdriver or a coin, and gently pry the
two halves of the key fob apart. Make sure not
to damage the seal during removal.

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
r u

bbing alcohol.
4. To assemble the key fob case, snap the two h
alves 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. 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
a u

thorized 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
s e
rviced, bring all vehicle keys with you to an
authorized dealer.
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
i g

nition 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
p os

ition, 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.
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,
s e
ek immediate medical attention.
Keep new and used batteries away from chil -
dren. If the battery compartment does not
c l
ose 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.
