The system uses a factory-mated key fob, a Keyless Push
Button Ignition and a RF receiver to prevent unauthorized
vehicle operation. Therefore, only key fobs that are pro-
grammed to the vehicle can be used to start and operate the
vehicle. The system will not allow the engine to crank with
an invalid key fob.
After placing the ignition to the ON/RUN position, 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 system. In
addition, if the light begins to flash after the bulb check, it
indicates that someone tried to use 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 seconds), it
indicates that there is a fault in the system. 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 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 Key Fobs
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 unattended.
• For vehicles equipped with Keyless Enter-N-Go —
Ignition, 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 programming
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 serviced,
bring all vehicle keys with you to an authorized dealer.
Customer Key Fob Programming
Programming key fobs may be performed at an authorized
dealer.

If something triggers the alarm, and no action is taken to
disarm it, the vehicle security alarm will turn the horn off
after 29 seconds, 5 seconds between cycles, up to 8 cycles if
the trigger remains active and then the vehicle security
alarm will rearm itself.

To Disarm The System
The vehicle security alarm can be disarmed using any of
the following methods:
• Push the unlock button on the key fob. •

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 previously
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, the horn will sound. If this occurs, disarm
the vehicle security alarm.
Security System Manual Override
The vehicle security alarm will not arm if you lock the
doors using the manual door lock plunger.
Tamper Alert
If something has triggered the vehicle security alarm in
your absence, the horn will sound three times and the
exterior lights will blink three times when you disarm the
vehicle security alarm. Check the vehicle for tampering.
ILLUMINATED ENTRY — IF EQUIPPED
The courtesy lights will turn on when you use the key fob
to unlock the doors or after opening any door.
This feature also turns on the approach lighting in the
outside mirrors (if equipped).
The courtesy lights will fade to off after approximately 30
seconds, or they will immediately fade to off once the
ignition is placed in the ON/RUN position from the OFF
position.NOTE:
•
The front courtesy overhead console and door courtesy
lights will turn on if the dimmer control is in the “Dome
ON” position (extreme top position).
• The Illuminated Entry system will not operate if the
dimmer control is in the “Dome defeat” position (ex-
treme bottom position).
REMOTE KEYLESS ENTRY
The Remote Keyless Entry system allows you to lock or
unlock the doors, open the trunk, or activate the Panic
Alarm from distances up to approximately 66 ft (20 m)
using a hand-held key fob. The key fob does not need to be
pointed at the vehicle to activate the system.
