Key-In-Ignition Reminder
Opening the driver’s door when the key is in the ignition
sounds a signal to remind you to remove the key.
NOTE: The Key-In-Ignition reminder only sounds when
the ignition key is placed in the LOCK or ACC position.
SENTRY KEY 
The Sentry Key  Immobilizer System prevents unauthor-
ized 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 ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized ve-
hicle operation. Therefore, only keys that are programmed
to the vehicle can be used to start and operate the vehicle.
The system will shut the engine off in two seconds if
someone uses an invalid key to try to start the engine. 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.16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

CAUTION!The Sentry Key  Immobilizer system is not compat-
ible with some after-market remote starting systems.
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 unattended.
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 Sys-
tem serviced, bring all vehicle keys with you to an
authorized dealer. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

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/RUN 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/RUN 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/RUN 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 com-
plete, the Vehicle Security Light will turn on again for
three seconds and then turn off.
The new Sentry Key  is programmed. The Remote Key-
less Entry (RKE) transmitter will also be programmed
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.18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 repro-
grammed.
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 unde-
sired operation. VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors,
swing gate, and ignition for unauthorized operation.
While the Vehicle Security Alarm is armed, interior
switches for door locks are disabled. The Vehicle Security
Alarm provides both audible and visible signals when
alarming. The horn will sound, the headlights will turn
on, the park lamps and/or turn signals will flash repeat-
edly for three minutes. If the disturbance is still present
(driver’s door, passenger door, other doors, ignition) after
three minutes, the headlights, park lamps and/or turn
signals will flash for an additional 15 minutes.
NOTE: The Panic Alarm and the Vehicle Security Alarm
are quite different. Please take a moment to activate the
Panic Alarm and the Vehicle Security Alarm 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. 2 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 19

Rearming The System
If something triggers the 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
The Vehicle Security Alarm will set when you use the
Remote Keyless Entry (RKE) transmitter to lock the doors
and swing gate, or when you use the power door lock
switch while the door is open. After all the doors are
locked and closed, the Vehicle Security Light (located on
the instrument cluster) will flash rapidly for about 16
seconds to signal that the Vehicle Security Alarm is
arming. During this 16-second arming period, opening
any door or the swing gate will cancel the arming. If the Vehicle Security Alarm is successfully set, the Vehicle
Security Light will flash at a slower rate to indicate the
Vehicle Security Alarm is armed.
To Disarm The System
To disarm the Vehicle Security Alarm, you will need to
press the UNLOCK button on the RKE transmitter, or
turn the ignition switch to the ON/RUN position. If
something has triggered the Vehicle Security Alarm in
your absence, the horn will sound three times and the
exterior lights blink three times when you unlock the
doors. Check the vehicle for tampering.
The Vehicle Security Alarm is designed to protect your
vehicle; however, you can create conditions where the
Vehicle Security Alarm will arm unexpectedly. If you
remain in the vehicle and lock the doors with the RKE
transmitter, once the Vehicle Security Alarm is armed
(after 16 seconds), when you pull the door handle to exit,20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the alarm will sound. If this occurs, press the UNLOCK
button on the RKE transmitter to disarm the Vehicle
Security Alarm. You may also accidentally disarm the
