SENTRY KEY
The Sentry Key Immobilizer system prevents
unauthorized 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, keyless push button
ignition and a Radio Frequency (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 cannot reprogram a key
fob obtained from another vehicle.
After placing the ignition switch in 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 electronics. In
addition, if the light begins to flash after the
bulb check, it indicates that someone
attempted to start the engine with an invalid key
fob. In the event that a valid key fob is used to
start the engine but there is an issue with the
vehicle electronics, the engine will start and
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 electronics. Should this occur,
have the vehicle serviced as soon as possible by
an authorized dealer.
All of the key fobs provided with your new
vehicle have been programmed to the vehicle
electronics.
KEY PROGRAMMING
Programming key fobs may be performed at an
authorized dealer.
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.
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.
CAUTION!
The Sentry Key Immobilizer system is not
compatible with some aftermarket remote
starting systems. Use of these systems may
result in vehicle starting problems and loss of
security protection.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.

VEHICLE SECURITY ALARM — IF EQUIPPED
The vehicle security alarm monitors the vehicle
doors for unauthorized entry and the keyless
push button ignition for unauthorized operation.
While the vehicle security alarm is armed,
interior switches for door locks and trunk
release are disabled. If something triggers the

Security System Manual Override
The vehicle security alarm will not arm if you
lock the doors using the manual door lock.
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.
Grasp the Passive Entry door handle, if
equipped. Refer to “Keyless Enter-N-Go —
Passive Entry” in “Doors” in this chapter for
further information.
Push the Keyless Enter-N-Go ignition button
(requires at least one valid key fob in the
vehicle).
NOTE:
The driver's door key cylinder and the trunk
button on the key fob cannot arm or disarm
the vehicle security alarm.
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 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.
REARMING OF THE SYSTEM
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, five seconds
between cycles, up to eight cycles if the trigger
remains active and the vehicle security alarm
will rearm itself.
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.
