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.

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).
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 the key
fob may reduce this range Ú page 449.
HOW TO USE REMOTE START
Push and release the Remote Start button on the
key fob twice within five seconds. The parking
lights will flash, vehicle doors will lock, and the
horn will chirp twice (if programmed). Once the
vehicle has started, the engine will run for
15 minutes.
Pushing the remote start button a third time
shuts the engine off.
To drive the vehicle, push the unlock button,
insert the key into the ignition, and turn to 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 operation is
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.
If your power door locks were unlocked,
Remote Start will automatically lock the
doors.
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.
