2010 JEEP LIBERTY immobilizer

WARNING!
Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be seri-
ously or fatally injured. Don’t leave the key in the
ignition. A child could operate power windows,
other controls, or move the vehicle.
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 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 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.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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. NOTE:
The Sentry Key Immobilizer System is not
compatible with some aftermarket remote starting sys-
tems. 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15

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 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.
3. Insert the second valid key into the ignition switch.
Turn the ignition switch to the ON position within
15 seconds. After 10 seconds, a chime will sound. In
addition, the Vehicle Security Light will begin to flash.
Turn the ignition switch to the LOCK position and
remove the second key.
4. Insert a blank Sentry Key
into the ignition switch.
Turn the ignition switch to the ON position within
60 seconds. After 10 seconds, a single chime will sound.
In addition, the Vehicle Security Light will stop flashing.
To indicate that programming is complete, the Vehicle
Security Light will turn on again for three seconds and
then turn off.
