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 operation. The key fob
allows you to lock or unlock the doors and trunk 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.
 With ignition in the ON position 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 can be verified by referring to
the instrument cluster, which will display directions to
follow
Úpage 284.
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 doors. Push and release the lock button on the
key fob to lock all doors.
When the doors are unlocked, the turn signals will flash
and the illuminated entry features will be activated. When
the doors are locked, the turn signals will flash and the
horn will chirp. This setting can be adjusted in the
Uconnect system
Úpage 107.
NOTE:
If the vehicle is unlocked with the key fob, and no door
is opened within 60 seconds, the vehicle will relock and
the Vehicle Security system (if equipped) will arm.
 If one or more doors are open, or the trunk is open, the
doors will lock. The doors will unlock again automati -
cally if the key fob is left inside the passenger compart -
ment, otherwise the doors will stay locked.

2. Separate the key fob halves using a flat-head
screwdriver or a coin, and gently pry the two halves of
the key fob apart. Make sure not to damage the seal
during removal.

NOTE:Separating the case can also be done with a flat-head
screwdriver.

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 deterioration. If you touch a battery, clean it
with rubbing alcohol.
4. To assemble the key fob case, snap the two halves together.
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 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
children.

GETTING TO KNOW YOUR VEHICLE15
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.
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.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics
Úpage 284.
IGNITION SWITCH
KEYLESS ENTER ‘N GO™ IGNITION
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.
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 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.

23_LA_OM_EN_USC_t.book Page 15

GETTING TO KNOW YOUR VEHICLE17
NOTE:
When opening the driver's door with the ignition in
ON/RUN (engine not running), a chime will sound to
remind you to place the ignition in the OFF position.
In addition to the chime, the message will display
“Ignition Or Accessory On” in the cluster.
 For more information on proper engine starting
procedures, see
Úpage 71.
REMOTE START — IF EQUIPPED
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 328 ft (100 m).
Remote Start is used to defrost windows in cold weather,
and to reach a comfortable climate in all ambient
conditions before the driver enters the vehicle.
NOTE:Obstructions between the vehicle and key fob may reduce
this range Úpage 284.
HOW TO USE REMOTE START
Push and release the Remote Start button on the key fob
twice within five seconds. The vehicle doors will lock, the
parking lights will flash, and the horn will chirp
(if programmed). Then, the engine will start, and the
vehicle will remain in the Remote Start mode for a
15 minute cycle. Pushing the Remote Start button a third
time shuts the engine off.
To drive the vehicle, push the unlock button, and place the
ignition in the ON/RUN position.
NOTE:
 With Remote Start, the engine will only run for
15 minutes.
 Remote Start can only be used twice. 
If an engine fault is present or fuel level is low, the
vehicle will start and then shut down in 10 seconds.
 The parking lights will turn on and remain on during
Remote Start mode.
 For security, power window and power sunroof opera -
tion (if equipped) are disabled when the vehicle is in
the Remote Start mode.
 The ignition must be placed in the ON/RUN position
before the Remote Start sequence can be repeated for
a third cycle.
All of the following conditions must be met before the
engine will remote start:
 Gear selector in PARK
 Doors closed
 Hood closed
 Trunk closed
 Hazard switch off
 Brake switch inactive (brake pedal not pressed)
 Battery at an acceptable charge level
 Panic button not pushed
 System not disabled from previous Remote Start event
 Vehicle Security system indicator flashing
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. Operation of the
Remote Start system, windows, door locks or other
controls could cause serious injury or death.
