2011 JEEP GRAND CHEROKEE immobilizer

Key-In-Ignition ReminderOpening the driver’s door when the Key Fob is
in the ignition and the ignition switch position is
OFF or ACC, sounds a signal to remind you to
remove the Key Fob.
NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or
ACC ignition position.
With the Keyless Enter-N-Go feature, opening
the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine
stopped) will cause the reminder chime to
sound. Refer to “Starting Procedures” in “Start-
ing And Operating” for further information.
SENTRY KEYThe 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 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
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 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 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.
CAUTION!
The Sentry Key
Immobilizer system is not
compatible 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 pro-
grammed to any other vehicle.
CAUTION!
• Always remove the Key Fobs from the
vehicle and lock all doors when leaving the
vehicle unattended.

ber to place the ignition in OFF.

provided with a four-digit Personal Identifica-
tion 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 authorized
dealer.
NOTE:
When having the Sentry Key Immobilizer
system serviced, bring all vehicle ignition
keys with you to an authorized dealer.
Customer Key ProgrammingProgramming Key Fobs or RKE transmitters
may be performed at an authorized dealer.

VEHICLE SECURITY ALARM —

The Vehicle Security Alarm monitors the hood,
liftgate, liftgate flipper glass, vehicle doors for
unauthorized entry, and the ignition switch for
unauthorized operation. If something triggers
the alarm, the Vehicle Security Alarm will pre-
vent the vehicle from starting and provide the
following audio and visual signals: the horn will

will flash, and the Vehicle Security Light in the
instrument cluster will flash.
To Arm the System
Vehicles Not Equipped with Keyless
Enter-N-Go
Remove the key from the ignition switch and
either press a power door lock switch while the
driver or passenger door is open, or press the
LOCK button on the Remote Keyless Entry
(RKE) transmitter. After the last door is closed,
or if all doors are closed, the Vehicle Security
Alarm will arm itself in about 16 seconds.
During that time, the Vehicle Security Light will
flash. If it does not illuminate, the Vehicle Secu-
rity Alarm is not arming. Also, if you open a door
during the arming period, the Vehicle Security
Alarm will cancel the arming process. If you
wish to rearm the Vehicle Security Alarm after
closing the door, you must repeat one of the
previously-described arming sequences.
Vehicles Equipped with Keyless
Enter-N-Go
Press the Keyless Enter-N-Go Start/Stop button
until the Electronic Vehicle Information Center
(EVIC) indicates that the vehicle ignition is
“OFF” (refer to “Starting Procedures” in “Start-
ing And Operating” for further information).
Then either press the power door LOCK switch
