The system uses ignition keys, which 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 (2)
seconds if someone uses an invalid key to start the engine.
NOTE:A key, which 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 Alarm Indicator Light will
turn on for three (3) 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 used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.If the Vehicle Security Alarm Indicator 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 ser-
viced as soon as possible.
NOTE:²The Sentry Key Immobilizer System is not compatible
with some after-market remote starting systems. Use
of these systems may result in vehicle starting prob-
lems and loss of security protection.
²Exxon/Mobil Speed Pass,Ÿ additional Sentry Keys, or
any other transponder-equipped components on the
same key chain willnotcause a key-related (transpon-
der) fault unless the additional part isphysically held
against the ignition keybeing used when starting the
vehicle. Cell phones, pagers, or other RF electronics
will not cause interference with this system.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 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 PIN number. Keep the PIN in a secure
location. This number is required for dealer replacement
of keys. Duplication of keys may be performed at anauthorized dealer or by using the Customer Key Pro-
gramming procedure. This procedure consists of pro-
gramming a blank key to the vehicle electronics. A blank
key is one, which has never been programmed.
NOTE: When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
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 ªONº position for at least 3 seconds,
but no longer than 15-seconds. Then, turn the ignition
switch to the ªLOCKº position and remove the first key.

3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ªONº position within 15
seconds. After ten seconds, a chime will sound. In
addition, the Vehicle Security Alarm Indicator Light will
begin to flash. Turn the ignition switch to the ªLOCKº
position and remove the second key.
4. Insert a blank Sentry Key into the ignition switch. Turn
the ignition switch to the ªONº position within 60
seconds. After 10 seconds, a single chime will sound. In
addition, the Vehicle Security Alarm Indicator Light will
stop flashing. To indicate that programming is complete,
the indicator light will turn on again for 3 seconds and
then turn off.
The new Sentry Key is programmed.The Keyless Entry
Transmitter will also be programmed during this pro-
cedure.
Repeat this procedure to program up to 8 keys. If you do
not have a programmed sentry key, contact your dealer
for details.NOTE:If a programmed key is lost, see your dealer to
have all remaining keys erased from the systems
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 the dealer at
the time of service to be reprogrammed.

NOTE:The steering wheel will lock when the key is
removed, and the steering wheel is turned around 115
degrees clockwise or 65 degrees counterclockwise from
the center position.
Ignition Accessory Delay Feature
For vehicles not equipped with the Electronic Vehicle
Information Center (EVIC),the power window switches,
radio, hands±free system (if equipped), and power out-
lets will remain active for 10 minutes after the ignition
switch is turned off. Opening either front door will cancel
this feature.For vehicles equipped with the Electronic Vehicle Infor-
mation Center (EVIC), the power window switches,
radio, hands±free system (if equipped), and power out-
lets will remain active for up to 10 minutes after the
ignition switch is turned off. Opening either front door
will cancel this feature. The time for this feature is
programmable. For details, refer to ªKEY OFF POWER
DELAY > OFFº under ªPersonal Settings (Customer
Programmable Features),º under ªElectronic Vehicle In-
formation Center (EVIC)º in Section 3 of this manual.
SECURITY ALARM SYSTEM Ð IF EQUIPPED
This system monitors the vehicle doors, liftgate, and
ignition for unauthorized operation. When the alarm is
activated, the system provides both audible and visual
signals. The horn will sound repeatedly for 3 minutes
and the headlights and security light in the instrument
cluster will flash for an additional 15 minutes. The engine
will not run until the system is disarmed.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Set the Alarm:
The alarm will set when you use the power door locks or
use the Keyless Entry transmitter to lock the doors. After
all the doors are locked and closed the security light in
the instrument cluster will flash rapidly to signal that the
system is arming. The security light in the instrument
panel cluster will flash rapidly for about 15 seconds to
indicate that the alarm is being set. After the alarm is set,
the security light will flash at a slower rate to indicate
that the system is armed.
NOTE:If the security light stays on continuously during
vehicle operation, have the system checked by your
dealer.
To Disarm the System:
Use the Keyless Entry transmitter to unlock the doors. If
something has triggered the system in your absence, the
horn will sound three times when you unlock the doors.
Check the vehicle for tampering.The security system will also disarm, if the vehicle is
started with a programmed Sentry Key. If an unpro-
grammed Sentry Key is used to start a vehicle, the engine
will start and run for 2 seconds and then shut down.
After six unsuccessul attempts at starting the engine, the
system will shut down until the correct key is used. To
exit alarming mode, press the RKE Unlock button or start
the vehicle with a programmed Sentry Key.
The security alarm system is designed to protect your
vehicle; however, you can create conditions where the
system will arm unexpectedly. If you remain in the
vehicle and lock the doors with the transmitter, the alarm
will sound when you pull the door handle to exit.
NOTE:You may accidentally activate the security sys-
tem (horn sounds and lights flash) by entering the vehicle
without using the key fob to unlock the door(s). The
security system can be disarmed with the key fob's
