2012 JEEP LIBERTY immobilizer

WARNING!
•When leaving the vehicle, always remove the key
fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle.
•Allowing children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured. Chil-
dren should be warned not to touch the parking
brake, brake pedal or the shift lever.
•Do not leave the key fob in or near the vehicle, and
do not leave the ignition in the ACC or ON/RUN
position. A child could operate power windows,
other controls, or move the vehicle.
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
CAUTION!
An unlocked vehicle is an invitation to thieves.
Always remove the key from the ignition, and lock
all doors when leaving the vehicle unattended.
Key-In-Ignition Reminder
If you open the driver’s door and the key is in the
ignition, a chime will sound to remind you to remove the
key.
NOTE:The Key-In-Ignition reminder only sounds
when the ignition key is placed in the LOCK or ACC
position.
SENTRY KEY
The Sentry Key Immobilizer System prevents unauthor-
ized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine.
NOTE:A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
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 Vehicle Security Light
begins to flash after the bulb check, it indicates that someone used an invalid key 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 sec-
onds), 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 compat-
ible 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 keys provided with your new vehicle have
been programmed to the vehicle electronics.

Replacement Keys
NOTE:Only keys that are programmed to the vehicle
electronics can be used to start and operate the vehicle.
Once a Sentry Key is programmed to a vehicle, it cannot
be programmed to any other vehicle.
CAUTION!
Always remove the Sentry Keys from the vehicle
and lock all doors when leaving the vehicle unat-
tended.
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 keys. Du-
plication of keys may be performed at an authorized
dealer or by following the customer key programming procedure. This procedure consists of programming a
blank key to the vehicle electronics. A blank key is one
that has never been programmed.
NOTE:
When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
If you have two valid Sentry Keys , you can program
new Sentry Keys to the system by performing the
following procedure:
1. Cut the additional Sentry Key Transponder blank(s)
to match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch. Turn
the ignition switch to the ON/RUN position for at least
three seconds, but no longer than 15 seconds. Then, turn
the ignition switch to the LOCK position and remove the
first key.
