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 electronics can be used to start and
operate the vehicle.
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 swal-
lowed or placed inside any part of the body,
seek immediate medical attention.
Keep new and used batteries away from chil -
dren. If the battery compartment does not
close securely, stop using the product and
keep it away from children.

18GETTING TO KNOW YOUR 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.
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.
All of the key fobs provided with your new vehicle
have been programmed to the vehicle electronics
Ú
page 427.
NOTE:A key fob that has not been programmed is also
considered an invalid key.
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 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 backup
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.
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.

VEHICLE SECURITY SYSTEM — IF EQUIPPED
The Vehicle Security system monitors the vehicle
doors and ignition for unauthorized operation.
When the Vehicle Security system is activated,
interior switches for door locks are disabled. If
something triggers the alarm, the Vehicle Security
system will provide the following audible and
visible signals:
The horn will pulse
The turn signals will flash
The Vehicle Security Light in the instrument
cluster will flash
TO ARM THE SYSTEM
Follow these steps to arm the Vehicle Security
system:

1. Make sure the vehicle’s ignition is placed in
the OFF position.

For vehicles equipped with Keyless Entry,
make sure the vehicle’s keyless ignition
system is OFF. 2. Perform one of the following methods to lock
the vehicle:
Push the lock button on the interior power
door lock switch with the driver and/or
passenger door open.
Push the lock button on the exterior Passive
Entry door handle with a valid key fob avail -
able in the same exterior zone Ú page 25.
Push the lock button on the key fob.
3. If any doors are open, close them.
The Vehicle Security system will set when you use
the power door locks, or use the key fob to lock the
doors. After all the doors are locked and closed,
the Vehicle Security Light, in the instrument panel
cluster, will flash rapidly for about 16 seconds to
indicate that the alarm is being set. After the alarm
is set, the Vehicle Security Light will flash at a
slower rate to indicate that the system is armed.
TO DISARM THE SYSTEM
The Vehicle Security system can be disarmed using
any of the following methods:

1. Push the unlock button on the key fob.

2. Grab the Passive Entry door handle with a valid key fob within 5 ft (1.5 m) of the Passive Entry
door handle (if equipped) Ú page 25.
3. Cycle the ignition out of the OFF position. The Vehicle Security system is designed to protect
your vehicle. However, you can create conditions
where the system will give you a false alarm. If one
of the previously described arming sequences has
occurred, the Vehicle Security system will arm
regardless of whether you are in the vehicle or not.
If you remain in the vehicle and open a door, the
alarm will sound. If this occurs, disarm the Vehicle
Security system.
If the Vehicle Security system is armed and the
battery becomes disconnected, the Vehicle
Security system will remain armed when the
battery is reconnected; the exterior lights will flash,
and the horn will sound. If this occurs, disarm the
Vehicle Security system.
REARMING OF THE SYSTEM
If something triggers the alarm, and no action is
taken to disarm it, the Vehicle Security system will
turn the horn off after a 29 second cycle (with five
seconds between cycles and up to eight cycles if
the trigger remains active), and then rearm itself.
SECURITY SYSTEM MANUAL OVERRIDE
The Vehicle Security system will not arm if you lock
the doors using the manual door lock.
Keep key fobs away from children. Operation
of the Remote Start system, windows, door
locks or other controls could cause serious
injury or death.
