2. Separating key fob halves requires screw removal (if equipped), and gently prying the two halves of the key
fob apart. Make sure not to damage the seal during
removal.
3. Remove the battery by turning the back cover over (battery facing downward) and tapping it lightly on a
solid surface such as a table or similar, then 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, reposition and secure the screw.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.
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 chil -
dren.
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™ Igni -
tion, always remember to place the ignition in the
OFF position when exiting the vehicle.

16GETTING TO KNOW YOUR VEHICLE
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. All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics
Úpage 262.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
IGNITION SWITCH
IGNITION NODE MODULE (IGNM) —
I
F EQUIPPED
The Ignition Node Module (IGNM) operates similar to an
ignition switch. It has four operating positions, three with
detents and one that is spring-loaded. The detent
positions are OFF, ACC, and ON/RUN. The START position
is a spring-loaded momentary contact position. When
released from the START position, the switch
automatically returns to the ON/RUN position.

Ignition Switch

KEYLESS ENTER ‘N GO™ IGNITION
(I
F EQUIPPED)
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.
The START/STOP ignition button has several operating
modes that are labeled and will illuminate when in
position. These modes are OFF, ACC, ON/RUN, and START.
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.
