KEYS
KEY FOB
Your vehicle uses a keyless ignition system. The
ignition system consists of a key fob and a
START/STOP push button ignition system. The
Remote Keyless Entry (RKE) system consists of
a key fob and Keyless Enter-N-Go feature.
NOTE:
The key fob may not be found if it is located next
to a mobile phone, laptop or other electronic
device; these devices may block the key fob’s
wireless signal.
The key fob allows you to lock or unlock all
doors, tailgate, and the RamBox (if equipped),
as well as release the tailgate, and 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.
NOTE:
In the ON/RUN position, all key fob buttons
will work until the vehicle reaches 2 mph
(4 km/h).
The key fob should not be placed next to the
wireless charging pad (if equipped).

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.
In a situation where the battery is low or fully
depleted, a back up method can be used to
operate the ignition switch. Put the nose side of
the key fob (side opposite of the emergency key)
against the START/STOP ignition button and
push to operate the ignition switch.
To Unlock The Doors And Tailgate

Push and release the unlock button on the key fob
once to unlock the driver’s door. Push the unlock
button twice within five seconds to unlock all
doors, the tailgate and the RamBox (if equipped).

2 — LED Indicator
3 — Lock

GETTING TO KNOW YOUR VEHICLE15

The turn signal lights will flash to acknowledge the
unlock signal. The illuminated entry system will
also turn on.

NOTE:
All doors can be programmed to unlock on the
first push of the unlock button. Refer to “Ucon -
nect Settings” in “Multimedia” for further infor -
mation.
To Lock The Doors And Tailgate
Push and release the lock button on the key fob
to lock all doors, the tailgate, and the RamBox
(if equipped). The turn signal lights will flash and
the horn will chirp to acknowledge the signal.
Sound Horn With Remote Key Lock — If
Equipped
This feature will cause the horn to chirp when
the doors are locked with the key fob. This
feature can be turned on or turned off through
the Uconnect Settings. NOTE:
Pushing the lock button on the key fob while you
are in the vehicle will activate the vehicle secu
-
rity alarm system. Opening a door with the
vehicle security alarm system activated will
cause the alarm to sound. Push the unlock
button to deactivate the vehicle security alarm
system.
Refer to “Vehicle Security Alarm” in this chapter
for further information.
Using The Panic Alarm
To turn the Panic Alarm feature on or off, push
the Panic button on the key fob. When the Panic
Alarm is activated, the turn signals will flash, the
horn will pulse on and off, and the interior lights
will turn on.
The Panic Alarm will stay on for three minutes
unless you turn it off by either pushing the Panic
button a second time or drive the vehicle at a
speed of 15 mph (24 km/h) or greater. NOTE:
The interior lights will turn off if you place the
ignition in the ACC or ON/RUN position while
the Panic Alarm is activated. However, the
exterior lights and horn will remain on.
You may need to be less than 35 ft (11 m)
from the vehicle when using the key fob to
turn off the Panic Alarm due to the radio
frequency noises emitted by the system.
Replacing The Battery In The Key Fob With
Remote Control
The replacement battery model is one CR2450
battery.
NOTE:
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.

Back Up Starting Method

NOTE:
The key fob may not be able to be detected by
the vehicle’s 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-go system from starting the vehicle.
Refer to "Starting The Engine" in "Starting And
Operating" for further information.REMOTE START — IF EQUIPPED
(GASOLINE)
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
approximately 300 ft (91 m).
NOTE:
Obstructions between the vehicle and the key
fob may reduce this range.
HOW TO USE REMOTE START
All of the following conditions must be met
before the engine will remote start:
Gear selector in PARK
Doors closed
Hood closed
Hazard switch off
Brake switch inactive (brake pedal not
pushed)
Battery at an acceptable charge level
PANIC button not pushed
Fuel meets minimum requirement
System not disabled from previous remote
start event
Vehicle security alarm not active
Malfunction Indicator Light is not illuminated
WARNING!
Do not start or run an engine in a closed
garage or confined area. Exhaust gas
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous and can cause serious injury or
death when inhaled.
Keep key fobs away from children. Opera -
tion of the Remote Start System, windows,
door locks or other controls could cause
serious injury or death.
