Key Fob
The Key Fob operates the ignition switch. Insert the
square end of the key fob into the ignition switch located
on the instrument panel and rotate to the desired posi-
tion. It also contains the Remote Keyless Entry (RKE)
transmitter and an emergency key, which stores in the
rear of the Key Fob.
The emergency key allows for entry into the vehicle on
the driver’s side should the battery in the vehicle or the
RKE transmitter go dead. The emergency key is also for
locking the glove box. You can keep the emergency key
with you when valet parking.
NOTE:Entering a vehicle using the emergency key with
the security alarm armed, will result in the alarm sound-
ing. Insert the Key Fob (even if the Key Fob battery is
dead) into the ignition switch to disarm security alarm.

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 the factory-mated Key Fob with Remote
Keyless Entry (RKE) transmitter and Wireless Ignition
Node (WIN) to prevent unauthorized vehicle operation.
Therefore, only Key Fobs 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 an
invalid Key Fob is used to start the engine.
After turning the ignition switch to the ON/RUN posi-
tion, 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 light begins to flash afterthe bulb check, it indicates that someone used an invalid
Key Fob 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!
•Do not make modifications or alterations to the
immobilizer system. Modifications or alterations to
the immobilization system may result in a loss of
security protection.
•The Sentry Key® Immobilizer system is not com-
patible 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 Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.
CAUTION!
•Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
•For vehicles equipped with Keyless Enter-N-Go™,
always remember to place the ignition in the OFF
position.
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 Key Fobs.
Duplication of Key Fobs may be performed at an autho-
rized dealer, this procedure consists of programming a
blank Key Fob to the vehicle electronics. A blank Key Fob
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.Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.

VEHICLE SECURITY ALARM — IF EQUIPPED
This Vehicle Security Alarm monitors the vehicle doors,
liftgate, liftgate flipper glass, and ignition for unauthor-
ized operation. When the alarm is activated, the interior
switches for door locks, power liftgate and flipper glass
are disabled. The Vehicle Security Alarm provides both
audio and visual signals, the horn will sound, the head-
lights will turn on, park lamps and/or turn signals will
flash repeatedly 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 min-
utes.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 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.

NOTE:
•The driver’s door key cylinder and the liftgate button
on the RKE transmitter cannot arm or disarm the
Vehicle Security Alarm.
•The Vehicle Security Alarm remains armed during
power liftgate entry. Pressing the liftgate button will
not disarm the Vehicle Security Alarm. If someone

door the alarm will sound.
•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
system will give you a false alarm. If one of the previ-
ously described arming sequences has occurred, the
Vehicle Security Alarm will arm regardless of whetheryou are in the vehicle or not. If you remain in the vehicle
and open a door, the alarm will sound. If this occurs,
disarm the Vehicle Security Alarm.
If the Vehicle Security Alarm is armed and the battery
becomes disconnected, the Vehicle Security Alarm will
remain armed when the battery is reconnected; the
exterior lights will flash, the horn 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.
ILLUMINATED ENTRY
