NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, 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 Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), 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:
The Sentry Key Immobilizer System is not
compatible with some aftermarket remote starting sys-
tems. Use of these systems may result in vehicle starting
problems and loss of security protection.
All of the keys provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE: Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the vehicle
and lock all doors when leaving the vehicle unat-
tended.

At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of keys. Du-
plication of keys may be performed at an authorized
dealer or by following the customer key programming
procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key 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.
Customer Key Programming
If you have two valid Sentry Keys , you can program
new Sentry Keys to the system by performing the
following procedure:
1. Cut the additional Sentry Key Transponder blank(s)
to match the ignition switch lock cylinder key code. 2. Insert the first valid key into the ignition switch. Turn
the ignition switch to the ON position for at least three
seconds, but no longer than 15 seconds. Then, turn the
ignition switch to the LOCK position and remove the first
key.
3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON position within
15 seconds. After 10 seconds, a chime will sound. In
addition, the Vehicle Security Light will begin to flash.
Turn the ignition switch to the LOCK position and
remove the second key.
4. Insert a blank Sentry Key
into the ignition switch.
Turn the ignition switch to the ON position within
60 seconds. After 10 seconds, a single chime will sound.
In addition, the Vehicle Security Light will stop flashing.
To indicate that programming is complete, the Vehicle
Security Light will turn on again for three seconds and
then turn off.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

The new Sentry Keyis programmed.The Remote
Keyless Entry (RKE) transmitter will also be pro-
grammed during this procedure.
Repeat this procedure to program up to eight keys. If you
do not have a programmed Sentry Key, contact your
authorized dealer for details.
NOTE: If a programmed key is lost, see your authorized
dealer to have all remaining keys erased from the sys-
tem’s memory. This will prevent the lost key from
starting your vehicle. The remaining keys must then be
reprogrammed. All vehicle keys must be taken to an
authorized dealer at the time of service to be
reprogrammed.
General Information
The Sentry Key system complies with FCC rules Part 15
and with RSS-210 of Industry Canada. Operation is
subject to the following conditions:
•This device may not cause harmful interference.
•This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.
VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors,
liftgate, and liftgate flip-up window for unauthorized
entry and ignition for unauthorized operation.
If something triggers the alarm, the Vehicle Security
Alarm will sound the horn intermittently, the headlights,
park lamps and/or turn signals and the Vehicle Security
Light in the instrument cluster will flash.
NOTE: The Panic and Security alarms are quite differ-
ent. Please take a moment to activate the Panic and the
Security modes to hear the differences in the horn. In case
one should go off in the future, you will need to know
which mode has been activated in order to deactivate it.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

Rearming of the System
If something triggers the Vehicle Security Alarm, and no
action is taken to disarm it, the Vehicle Security Alarm
will turn off the horn after three minutes, turn off all of
the visual signals after 15 minutes, and then the Vehicle
Security Alarm will rearm itself.
To Arm the System
1. Remove the key from the ignition switch and exit the
vehicle.
2. Lock the doors and liftgate by pressing the power door
LOCK switch or the LOCK button on the Remote Keyless
Entry (RKE) transmitter.
NOTE:The Vehicle Security Alarm will not arm if you
lock the doors with the manual door lock plungers or the
driver’s door lock cylinder.
3. Close all doors. The Vehicle Security Light in the
instrument cluster will flash rapidly for about 16 seconds to signal that the Vehicle Security Alarm is arming.
During this period, opening any door or the liftgate will
cancel the arming process. If the Vehicle Security Alarm
arms successfully, the Vehicle Security Light will flash at
a slower rate to indicate the alarm is set.
NOTE:
For added security, whenever the Security
Alarm is armed, the HomeLink/Garage Door Opener
(if equipped) is disabled as well.
To Disarm the System
Either press the UNLOCK button on the RKE transmitter
or insert a valid Sentry Key into the ignition lock
cylinder and turn the key to the ON position.
NOTE:
•Unlocking the doors with the manual door lock plung-
ers or the driver’s door lock cylinder will not disarm
the Vehicle Security Alarm.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•When the Vehicle Security Alarm is armed, the interior
power door lock switches will not unlock the doors.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will give you a false alarm. If the
previously described arming sequence has occurred, the
Vehicle Security Alarm will arm regardless of whether
you are inside or outside the vehicle. If you remain inside
the vehicle and open a door, the alarm will sound. If this
occurs, disarm the Vehicle Security Alarm.
Tamper Alert
If something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times when you
unlock the doors. Check the vehicle for tampering.
ILLUMINATED ENTRY SYSTEM
The interior lights will turn on when you use the Remote
Keyless Entry (RKE) transmitter to unlock the vehicle or

under “Personal Settings (Customer-Programmable Fea-
tures)” under “Electronic Vehicle Information Center
(EVIC)” in Section 4.
The interior lights will fade to off after approximately
30 seconds or they will immediately fade to off once the
ignition switch is turned ON.
NOTE:
•The Illuminated Entry system will not operate the
interior lights if the dimmer control is in the extreme
downward position.
REMOTE KEYLESS ENTRY (RKE)
This system allows you to lock or unlock the doors and
liftgate, open the liftgate flip-up window, or activate the
PANIC alarm from distances up to approximately 66 ft
(20 m) using a hand-held Remote Keyless Entry (RKE)
transmitter. The RKE transmitter does not need to be
