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
vehicle operation. Therefore, only keys that are pro-
grammed 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.
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 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/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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 Keyinto 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 complete, the Vehicle
Security Light will turn on again for three seconds and
then turn off.
The new Sentry Key is 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 repro-
grammed. All vehicle keys must be taken to an authorized
dealer at the time of service to be reprogrammed.

and with RSS-210 of Industry Canada. Operation is

VEHICLE SECURITY ALARM — IF EQUIPPED
The Vehicle Security Alarm monitors the vehicle doors,
liftgate, and liftgate flipper glass for unauthorized entry
and ignition for unauthorized operation. While the Ve-
hicle Security Alarm is armed, interior switches for door
locks and flipper glass are disabled.
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 for three min-
utes. 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 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.
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.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 is
set successfully, the Vehicle Security Light will flash at a
slower rate to indicate the alarm is armed.
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/RUN 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.
•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 and the
exterior lights blink three times when you unlock the
doors. Check the vehicle for tampering.

need to know which mode has been activated in order to
deactivate it.
To turn the PANIC Alarm feature ON or OFF, press and
hold the PANIC button on the RKE transmitter for at
least one second and release. When the PANIC Alarm is

Keyless Entry (RKE) system will function normally.
PANIC mode will not disarm the Security System on
vehicles so equipped.
NOTE:You may need to be close to the vehicle when
using the RKE transmitter to turn off the PANIC Alarm
due to the radio frequency noises emitted by the system.
Programming Additional Transmitters
