GETTING TO KNOW YOUR VEHICLE
KEYS
KEY FOB

Your vehicle is equipped with a key fob which
supports Remote Keyless Entry (RKE) (if
equipped) and Keyless Enter-N-Go (if equipped).

If the vehicle is equipped with remote power
door locks, the key fob allows you to lock or
unlock all doors, 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.
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.
The key fob should not be placed next to the
wireless charging pad (if equipped).
In the ON/RUN position, all key fob buttons
will work until the vehicle reaches 2 mph
(4 km/h).
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.
To Lock/Unlock The Doors
If the vehicle is equipped with remote power
door locks, 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. If the vehicle is
equipped with remote power door locks, push
and release the lock button on the key fob to
lock all doors.

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.
NOTE:
The key fob battery should only be replaced by
qualified technicians. If the battery requires
replacement, see an authorized dealer.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 449.
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
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.

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 449.IGNITION SWITCH
KEYLESS PUSH BUTTON IGNITION
This feature allows the driver to operate the
ignition switch with the push of a button as long
as the Remote Keyless Entry key fob is in the
passenger compartment.

The Keyless Push Button Ignition has four
operating positions; three of which are labeled
and will illuminate when in position. The three
positions are OFF, ACC, and ON/RUN. The fourth
position is START. During START, RUN will
illuminate.

NOTE:

In case the ignition switch does not change with
the push of a button, the key fob may have a low
or depleted battery. In this situation, a back up
method can be used to operate the ignition
switch. Put the nose side (side opposite of
the emergency key) of the key fob against the
START/STOP ignition button, with your foot
applied on the brake pedal, and push to
operate the ignition switch. Keyless Push Button Ignition

The push button ignition can be placed in the
following modes:
OFF
The engine is stopped.
Some electrical devices (e.g. central locking,
alarm, etc.) are still available.
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.

method can be used to operate the ignition
switch. Put the nose side (side opposite of the
emergency key) of the key fob against the
START/STOP ignition button and push to
operate the ignition switch.
Back Up Starting Method

NOTE:The key fob may not be detected by the
vehicle 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 Enter-N-Go system from
starting the vehicle.
For more information on the engine starting
procedure, see Ú page 118.
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.

Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped with
Keyless Enter-N-Go in the ON/RUN mode.
A child could operate power windows, other
controls, or move the vehicle.

Do not leave children or animals inside
parked vehicles in hot weather. Interior heat
build-up may cause serious injury or death.

CAUTION!
An unlocked vehicle is an invitation for
thieves. Always remove key fob from the
vehicle and lock all doors when leaving the
vehicle unattended.
