SENTRY KEY®
The Sentry Key® Immobilizer System prevents unau-
thorized 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 a Key Fob with a factory-mated Remote
Keyless Entry (RKE) transmitter, an Ignition Node Mod-
ule, Keyless Push Button Ignition and a RF receiver 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 not allow
the engine to crank if an invalid Key Fob is 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.
NOTE:A Key Fob that has not been programmed is also
considered an invalid key. 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 light begins to flash after
the bulb check, it indicates that someone used an invalid
Key Fob 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 by an authorized dealer.

CAUTION!
The Sentry Key® Immobilizer 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.
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.
NOTE: Duplication of Key Fobs may be performed at an
authorized dealer. This procedure consists of program-
ming a blank Key Fob to the vehicle electronics. A blank
Key Fob is one that has never been programmed.
When having the Sentry Key® Immobilizer System ser-
viced, bring all vehicle keys with you to an authorized
dealer.
20 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.
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.
NOTE: Changes or modifications not expressly approved
by the party responsible for compliance could void the
user’s authority to operate the equipment.
VEHICLE SECURITY ALARM
The Vehicle Security Alarm monitors the vehicle doors
and ignition for unauthorized operation. When the Ve-
hicle Security Alarm is activated, interior switches for
door locks are disabled. The system provides both au-
dible and visible signals for the first three minutes the
horn will sound and the headlights will turn on, the park
lamps and/or turn signals will flash and Vehicle Security
Light will flash repeatedly. For an additional 15 minutes
only, the headlights will turn on, the park lamps and/or
turn signals, and Vehicle Security Light will flash.
Rearming Of The System
The Vehicle Security Alarm will rearm itself after the 15
additional minutes of headlights and Vehicle Security
Light flashing, if the system has not been disabled. If the
condition which initiated the alarm is still present, the
system will ignore that condition and monitor the re-
maining doors and ignition.

To Arm The System
Follow these steps to arm the Vehicle Security Alarm:
1. Remove the key from the ignition system (refer toStarting Procedures inStarting And Operating for
further information).
• For vehicles equipped with Keyless Enter-N-Go™,
make sure the vehicle ignition system is OFF.
• For vehicles not equipped with Keyless Enter-N-
Go™, make sure the vehicle ignition system is OFF
and the key is physically removed from the ignition.
2. Perform one of the following methods to lock the vehicle:
• Push LOCK on the interior power door lock switch
with the driver and/or passenger door open. •
Push the LOCK button on the exterior Passive Entry
Door Handle with a valid Key Fob available in the
same exterior zone (refer to Keyless Enter- N-Go™
in Things To Know Before Starting Your Vehicle for
further information).
• Push the LOCK button on the Remote Keyless Entry
(RKE) transmitter.
3. If any doors are open, close them.
The Vehicle Security Alarm will set when you use the
power door locks, or use the Remote Keyless Entry (RKE)
transmitter to lock the doors. After all the doors are
locked and closed, the Vehicle Security Light, in the
instrument panel cluster, will flash rapidly for about 16
seconds to indicate that the alarm is being set. After the
alarm is set, the Vehicle Security Light will flash at a
slower rate to indicate that the system is armed.
22 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

To Disarm The System
The Vehicle Security Alarm can be disarmed using any of
the following methods:
1. Push the UNLOCK button on the Remote KeylessEntry (RKE) transmitter.
2. Grasp the Passive Entry Unlock Door Handle with a valid Key Fob within 5 ft (1.5 m) of the passive entry
door handle (if equipped, refer to Keyless Enter-N-
Go™ inThings To Know Before Starting Your Ve-
hicle for further information).
3. Cycle the vehicle ignition system out of the OFF position.
• For vehicles equipped with Keyless Enter-N-Go™,
push the Keyless Enter-N-Go™ Start/ Stop button
(requires at least one valid Key Fob in the vehicle). •
For vehicles not equipped with Keyless Enter-N-
Go™, insert a valid key into the ignition switch and
turn the key to the ON position.
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 whether
you 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, and the horn will sound. If this
occurs, disarm the Vehicle Security Alarm.
