2009 JEEP GRAND CHEROKEE immobilizer

Key-In-Ignition Reminder
If you open the driver’s door with the integrated ignition
key in the ignition, a chime will sound to remind you to
remove the key.
NOTE:The Key-In-Ignition reminder only sounds
when the integrated ignition key is placed in the LOCK
or ACC position.
SENTRY KEY
The Sentry KeyImmobilizer system prevents unautho-
rized 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 Remote Keyless Entry
(RKE) transmitter with integrated key and Wireless Igni-
tion Node (WIN) to prevent unauthorized vehicle opera-
tion. Therefore, only RKE transmitters that are pro-
grammed to the vehicle can be used to start and operatethe vehicle. The system will shut the engine off in two
seconds if an invalid RKE transmitter is used to start the
engine.
After turning the ignition switch to the ON 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 RKE transmitter
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.

NOTE:
•The Sentry KeyImmobilizer system is not compatible
with aftermarket remote starting systems. Use of these
systems may result in vehicle starting problems and
loss of security protection.
•Exxon/Mobil Speedpass™, additional RKE transmit-
ters, or any other transponder-equipped components
on the same key chainwill notcause a fault unless the
additional part isphysically held against the RKE
transmitterbeing used to start the vehicle. Cell
phones, pagers, or other RF electronics will not cause
interference with this system.
All of the RKE transmitters provided with your new
vehicle have been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only RKE transmitters that are programmed to
the vehicle electronics can be used to start and operatethe vehicle. Once an RKE transmitter is programmed to a
vehicle, it cannot be programmed to any other vehicle.
CAUTION!
Always remove the keys from the vehicle and lock all
doors when leaving the vehicle unattended.
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 RKE trans-
mitters. Duplication of RKE transmitters may be per-
formed at an authorized dealer or by using the Customer
Key Programming procedure. This procedure consists of
programming a blank transmitter to the vehicle electron-
ics. A blank transmitter is one that has never been
programmed.
18 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:When having the Sentry KeyImmobilizer
system serviced, bring all vehicle RKE transmitters with
you to the authorized dealer.
Customer Key Programming
If you have two valid RKE transmitters with integrated
keys, you can program new transmitters to the system by
performing the following procedure:
1. Insert the first valid integrated key into the ignition
switch and turn the ignition switch to the ON position for
at least three seconds, but no longer than 15 seconds.
Turn the ignition switch to the LOCK position and
remove the first key.
2. Insert the second valid integrated key and turn the
ignition switch to the ON position within 15 seconds.
After 10 seconds, a chime will sound and the Vehicle
Security Light will begin to flash. Turn the ignition switch
to the LOCK position and remove the second key.3. Insert a blank integrated key into the ignition switch
and turn the ignition switch to the ON position within
60 seconds. After 10 seconds, a single chime will sound
and the Vehicle Security Light will stop flashing, turn on
again for three seconds, and then turn off.
The new integrated key is programmed.The RKE trans-
mitter will also be programmed during this procedure.
Repeat this procedure to program up to eight keys. If you
do not have a programmed RKE transmitter with inte-
grated key, contact your authorized dealer for details.
NOTE:If a programmed key is lost, see your authorized
dealer to have all remaining keys erased from the sys-
tem’s memory. This will prevent the lost key from
starting your vehicle. The remaining keys must then be
reprogrammed. All vehicle keys must be taken to an
authorized dealer at the time of service to be
reprogrammed.
