SENTRY KEY
The Sentry KeyImmobilizer System prevents unautho-
rized 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
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 threeseconds 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 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
seconds), it indicates that there is a fault in the electron-
ics. Should this occur, have the vehicle serviced as soon
as possible.
NOTE:
•The Sentry KeyImmobilizer System is not compat-
ible with some aftermarket remote starting systems.
Use of these systems may result in vehicle starting
problems and loss of security protection.

•Exxon/Mobil Speedpass™, additional Sentry Keys,
or any other transponder-equipped components on
the same key chain willnotcause a key-related
(transponder) fault unless the additional part isphysi-
cally held against the ignition keybeing used when
starting the vehicle. Cell phones, pagers, or other RF
electronics will not cause interference with this system.
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 Keyis programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keysfrom 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 KeyImmobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Customer Key Programming
If you have two valid Sentry Keys, you can program
new Sentry Keysto the system by performing the
following procedure:
1. Cut the additional Sentry KeyTransponder 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 Keyinto the ignition switch.
Turn the ignition switch to the ON position within 60seconds. 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 Secu-
rity Light will turn on again for three seconds and then
turn off.
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 repro-
grammed.

General Information
The Sentry Keysystem 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.
SECURITY ALARM SYSTEM — IF EQUIPPED
This Security Alarm System monitors the doors, hood,
liftgate, and ignition switch for unauthorized operation.
If something triggers the Security Alarm, the Security
Alarm System will sound the horn for 30 seconds and
flash the lights for 60 seconds. If the triggering device is
not deactivated, the horn will sound again after a fivesecond delay for another 30 seconds. If the trigger
remains present, this cycle will repeat for up to five
minutes.
To Set The Security Alarm
1. Remove the key from the ignition switch and get out
of the vehicle.
2. Lock the door using either the power door LOCK
switch or the Remote Keyless Entry (RKE) transmitter
and close all doors.
3. The Security Alarm indicator light in the instrument
cluster will flash rapidly for 16 seconds. This shows that
the system is arming. During this period, if a door is
opened, the ignition switch is turned ON, or the power
door locks are unlocked in any manner, the Security
Alarm will automatically disarm. After 16 seconds, the
Security Alarm indicator light will flash slowly. This
shows that the Security Alarm System is fully armed.
