Power Locks are standard equipment. Two ignition
keys with integral Remote Keyless Entry (RKE) trans-
mitters are supplied with the vehicle. They operate the
ignition and the locks in the driver’s door and glove
box. The driver’s door lock cylinder is the only external
key cylinder on the vehicle. The power lock system
enables the doors, liftgate and fuel door to be locked
and unlocked in the following ways:

•

With the driver’s door lock cylinder.

•

With the RKE transmitter.

•

With the power lock switch located on the center
console (except fuel door).

Each door can be locked or unlocked mechanically
and independently with either its inside lock knob,
inside remote release handle, or the outside key cyl-
inder lock (driver door only). All power locks, including
the rear liftgate and fuel door, can be remotely locked
or unlocked with the Remote Keyless Entry (RKE)
transmitter.

Central Locking

Central Locking is a part of the power locking system and the Vehicle Theft Security System. Central Locking oper-
ates both door locks, rear liftgate lock, and the fuel door lock from a single point depending on the Customer Pref-
erences setting. It uses the Body Control Module (BCM), Central Locking Pump/Security System Module and
SKREEM Module for collective logic.

Door Lock Inhibit

The Door Lock Inhibit feature is part of Central Locking and prevents locking with a door lock button or the Remote
Keyless Entry transmitter when the ignition switch is in the ON/RUN position. It also prevents locking if either door
is not closed.

Sentry Key Remote Entry

The Sentry Key Remote Entry system allows unlock-
ing (1) and locking (2) of the vehicle doors, the rear
liftgate, and the fuel door by remote control using a
hand held radio frequency keyless entry transmitter. It
also has a red panic button (6), and incorporates a flip
out (3) ignition key (4) with an LED (5) battery check
indicator lamp.

OPERATION

The Power Lock System is operated with pneumatic supply lines connected to actuators at each power lock. Lock-
ing and unlocking is accomplished when the Body Control Module (BCM) is actuated by the Sentry Key Remote
Entry Module (SKREEM). The BCM then transmits a signal to the Central Locking Pump/Security System Module
via the Controller Area Network (CAN) bus. The Central Locking Pump/Security System Module incorporates a
pump to supply pressure or vacuum and valves which direct the supply via pneumatic supply lines to the Power
Lock System component.

For additional information about the BCM, SKREEM or Central Locking Pump/Security System Module functions as
they relate to the power locks system, refer to electronic control modules in this section.

Note: The power door locks and rear liftgate lock actuators are not serviced separately. They are part of the
door lock or rear liftgate lock assemblies. Refer to Door Latch Assembly or Liftgate Lock Actuator in this
section for removal and installation information.

Central Locking

To operate Central Locking using the ignition key, turn the driver’s door lock cylinder counterclockwise to lock and
clockwise to unlock both doors, rear liftgate, and fuel door. Using the keyless entry transmitter, press the lock button
to lock the doors, rear liftgate, and fuel door and the unlock button to unlock the doors (driver’s door an fuel door
only in selective mode), rear liftgate and fuel door. Using the power lock switch, press the upper portion to unlock
and the lower portion to lock both doors, and the rear liftgate. Unlocking the vehicle with the ignition key or the
keyless entry transmitter operates the Central Locking System and disarms the anti-theft alarm.

Remote Keyless Entry

The Remote Keyless Entry transmitter has four buttons for operation. They are UNLOCK, LOCK, PANIC, and IGNI-
TION KEY RELEASE. Both the Lock and Unlock buttons have embossed ISO symbols. The Remote Keyless Entry
transmitter has the ability to toggle the system between a Global mode or a Selective mode. (Refer to 8 - ELEC-
TRICAL/POWER LOCKS - STANDARD PROCEDURE). The Unlock button when pressed will unlock the doors, rear
liftgate and fuel door, and flash the turn signal lamps one time to indicate the vehicle is unlocked. The Lock button
when pressed will lock the doors, rear liftgate and fuel door, and flash the turn signal lamps three times to indicate
the vehicle is locked. If the lamps do not flash during locking, a door or the rear liftgate is not closed properly. The
Panic button when pressed for at least one second will cause the exterior lamps to flash and a panic alarm to sound
for three minutes. To deactivate, press the Panic button a second time or turn the ignition switch to the ON/RUN
position. The Ignition Key Release button allows the key blade in the Remote Keyless Entry transmitter to flip open
from the stored position.

The Sentry Key Remote Entry Module (SKREEM) transceiver is capable of retaining an access code even when
power is removed. The module retains in memory the ID numbers of any Ignition Key transponder that is pro-
grammed into it. For added system security, each SKREEM is programmed with a unique secret key code. Addi-
tional and/or replacement keys can be obtained only from a Chrysler dealer.

Automatic Relocking Function

To avoid unlocking the vehicle unintentionally, the vehicle is automatically relocked by the Central Locking Pump/
Security System Module via the SKREEM. Automatic Relocking takes place after the vehicle has been unlocked
with either the Remote Keyless Entry Transmitter or the driver’s door lock cylinder. The vehicle will be relocked if the
SKREEM module doesn’t receive a message within 40 seconds from any of the following:

•

An open door signal.

•

The key in the ignition sense.

•

The power lock switch signal.

•

The rear liftgate signal.

Automatic Locking

The power lock switch in the center console operates the automatic locking feature. With the ignition switch in the
ON/RUN position, pressing and holding the upper portion of the power lock switch for at least five seconds activates
automatic locking. With the automatic locking feature activated, the doors and rear liftgate will lock upon reaching a
speed of approximately 15 km/h (9 MPH). If after automatic locking is active, the vehicle is unlocked with the interior
power lock switch, this state is maintained until a door is opened, or until the ignition is turned off. Automatic locking
is accomplished again only upon reaching the specified speed. The logic circuitry for automatic locking is integrated
into the Central Locking Pump/Security System Module. The automatic locking feature can also be toggled or inhib-
ited with the DRB III

, for additional information see Toggling Customer Preferences in this section.

Emergency Unlocking

In the event of a vehicle collision, the doors are unlocked automatically by a crash sensor integrated into the Central
Locking Pump/Security System Module. The doors are unlocked after a delay time of 8 to 11 seconds. The emer-
gency unlocking function interrupts all functions performed by the Central Locking Pump/Security System Module,
which are reactivated only after interrupting the ignition. The emergency unlocking function is only active when the
vehicle is unlocked from the outside.

DIAGNOSIS AND TESTING - POWER LOCKS

The most reliable, efficient, and accurate means to diagnose the Power Lock System requires the use of a
DRB III

scan tool and the proper Diagnostic Procedures. Refer to Power Locks Electrical Diagnostics in

this section.

WARNING: REFER TO RESTRAINTS BEFORE ATTEMPTING ANY DOOR, SEAT, STEERING WHEEL, STEER-
ING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PER-
SONAL INJURY. (Refer to 8 - ELECTRICAL/RESTRAINTS - WARNING).

There are three main Electronic Control Modules which are interdependent on each other to complete lock/unlock
commands, they are the BCM, SKREEM, and Central Locking Pump/Security System Module. These modules can-
not be adjusted or repaired. For complete power locks diagnosis procedures, refer to Power Locks Electrical Diag-
nostics in this section.

PNEUMATIC SUPPLY LINES

The Power Lock Actuators are controlled by pneumatic supply lines that transfer either vacuum or pressure from the
Central Locking Pump/Security System Module to the component through distributors. When trouble shooting prob-
lems related to the pneumatic portion of the power lock system, a preliminary inspection should be performed to
determine that the pneumatic supply lines and harness connectors are free from kink or blockage damage. If nec-
essary, repairs to the pneumatic supply lines or harness connectors must be performed first before proceeding with
additional Power Lock System diagnosis.
