GENERAL INFORMATION
INTRODUCTION
The Smart Key Immobilizer System (SKIS) is
available factory-installed optional equipment for this
model. Following are some general descriptions of the
features and components of the SKIS. Refer to the
vehicle owner's manual for more information on the
use and operation of the SKIS. Refer to 8W-30 - Fuel/
Ignition System in Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
SMART KEY IMMOBILIZER SYSTEM
The Smart Key Immobilizer System (SKIS) is
designed to provide passive protection against unau-
thorized vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Smart Key Immo-
bilizer Module (SKIM), the Smart Key transponder,
the SKIS indicator lamp, and the Powertrain Control
Module (PCM), for gasoline engines, and the Body
Control Module (BCM) for diesel engines.
The SKIM is installed on the steering column near
the ignition lock cylinder. The transponder is located
under the molded rubber cap on the head of the igni-
tion key. The SKIS indicator lamp is located in the
instrument cluster.
The SKIS includes two valid Smart Key transpon-
ders from the factory. If the customer wishes, addi-
tional non-coded blank Smart Keys are available.
These blank keys can be cut to match a valid ignition
key, but the engine will not start unless the key tran-
sponder is also programmed to the vehicle. The SKIS
will recognize no more than eight valid Smart Key
transponders at any one time.
The SKIS performs a self-test each time the igni-
tion switch is turned to the On position, and will
store Diagnostic Trouble Codes (DTCs) if a systemmalfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRB
scan tool as described in the proper Diagnostic Pro-
cedures manual.
DESCRIPTION AND OPERATION
SMART KEY IMMOBILIZER MODULE
The Smart Key Immobilizer Module (SKIM) con-
tains a Radio Frequency (RF) transceiver and a cen-
tral processing unit, which includes the Smart Key
Immobilizer System (SKIS) program logic. The SKIS
programming enables the SKIM to program and
retain in memory the codes of at least two, but no
more than eight electronically coded Smart Key tran-
sponders. The SKIS programming also enables the
SKIM to communicate over the Chrysler Collision
Detection (CCD) data bus network with the Power-
train Control Module (PCM), the instrument cluster
and/or the DRB scan tool.
The SKIM transmits and receives RF signals
through a tuned antenna enclosed within a molded
plastic ring formation that is integral to the SKIM
housing. When the SKIM is properly installed on the
steering column, the antenna ring is oriented around
the circumference of the ignition lock cylinder hous-
ing. This antenna ring must be located within eight
millimeters (0.31 inches) of the Smart Key in order
to ensure proper RF communication between the
SKIM and the Smart Key transponder.
For added system security, each SKIM is pro-
grammed with a unique ªSecret Keyº code and a
security code. The SKIM keeps the ªSecret Keyº code
in memory and sends the code over the CCD data
bus to the PCM, which also keeps this code in its
memory. The SKIM also sends the ªSecret Keyº code
to each of the programmed Smart Key transponders.
The security code is used by the assembly plant to
NS/GSVEHICLE THEFT/SECURITY SYSTEMS 8Q - 1

access the SKIS for initialization, or by the dealer
technician to access the system for service. The
SKIM also stores in its memory the Vehicle Identifi-
cation Number (VIN), which it learns through a CCD
data bus message from the PCM during initializa-
tion.
The SKIM and the PCM both use software that
includes a rolling code algorithm strategy, which
helps to reduce the possibility of unauthorized SKIS
disarming. The rolling code algorithm ensures secu-
rity by preventing an override of the SKIS through
the unauthorized substitution of the SKIM or the
PCM. However, the use of this strategy also means
that replacement of either the SKIM or the PCM
units will require a system initialization procedure to
restore system operation.
When the ignition switch is turned to the On or
Start positions, the SKIM transmits an RF signal to
excite the Smart Key transponder. The SKIM then
listens for a return RF signal from the transponder
of the Smart Key that is inserted in the ignition lock
cylinder. If the SKIM receives an RF signal with
valid ªSecret Keyº and transponder identification
codes, the SKIM sends a ªvalid keyº message to the
PCM over the CCD data bus. If the SKIM receives
an invalid RF signal or no response, it sends ªinvalid
keyº messages to the PCM. The PCM will enable or
disable engine operation based upon the status of the
SKIM messages.
The SKIM also sends messages to the instrument
cluster over the CCD data bus network to control the
SKIS indicator lamp. The SKIM sends messages to
the instrument cluster to turn the lamp on for about
three seconds when the ignition switch is turned to
the On position as a bulb test. After completion of
the bulb test, the SKIM sends bus messages to keep
the lamp off for a duration of about one second. Then
the SKIM sends messages to turn the lamp on or off
based upon the results of the SKIS self-tests. If the
SKIS indicator lamp comes on and stays on after the
bulb test, it indicates that the SKIM has detected a
system malfunction and/or that the SKIS has become
inoperative.
If the SKIM detects an invalid key when the igni-
tion switch is turned to the On position, it sends
messages to the instrument cluster to flash the SKIS
indicator lamp. The SKIM can also send messages to
the instrument cluster to flash the lamp and to gen-
erate a single audible chime tone.
For diagnosis or initialization of the SKIM and the
PCM, a DRB scan tool and the proper Diagnostic
Procedures manual are required. The SKIM cannot
be repaired and, if faulty or damaged, the unit must
be replaced.SMART KEY IMMOBILIZER TRANSPONDER
The Smart Key Immobilizer System (SKIS) uses a
transponder that is integral to each of the two igni-
tion keys that are supplied with the vehicle when it
is shipped from the factory. The transponder chip is
insulated within a nylon mount inserted in the head
of the key, and invisible beneath a molded rubber cap
(Fig. 1).
Each Smart Key transponder has a unique tran-
sponder identification code programmed into it by the
manufacturer. The Smart Key Immobilizer Module
(SKIM) has a unique ªSecret Keyº code programmed
into it by the manufacturer. When a Smart Key tran-
sponder is programmed into the memory of the
SKIM, the SKIM learns the transponder identifica-
tion code from the transponder, and the transponder
learns the ªSecret Keyº code from the SKIM. Each of
these codes is stored within the transponder and in
the nonvolatile memory of the SKIM. Therefore,
blank keys for the SKIS must be programmed by and
into the SKIM, in addition to being cut to match the
mechanical coding of the ignition lock cylinder. See
Smart Key Immobilizer System Transponder Pro-
gramming in this group for more information.
The Smart Key transponder is within the range of
the SKIM transceiver antenna ring when it is
inserted in the ignition lock cylinder. When the igni-
tion switch is turned to the Start or On positions, the
SKIM transceiver issues a Radio Frequency (RF) sig-
nal that excites the transponder chip. The transpon-
der chip responds by issuing an RF signal containing
its transponder identification code and the ªSecret
Keyº code. The SKIM transceiver compares the tran-
sponder codes with the codes stored in its memory to

determine whether a valid key is in the ignition lock
cylinder.
The Smart Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SMART KEY IMMOBILIZER SYSTEM INDICATOR
LAMP
The Smart Key Immobilizer System (SKIS) indica-
tor lamp gives an indication when the SKIS is faulty
or when the vehicle has been immobilized due to the
use of an invalid ignition key. The lamp is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Smart Key Immobilizer Mod-
ule (SKIM) on the Chrysler Collision Detection (CCD)
data bus.
The SKIM sends messages to the instrument clus-
ter to turn the lamp on for about three seconds when
the ignition switch is turned to the On position as a
bulb test. After completion of the bulb test, the SKIM
sends bus messages to keep the lamp off for a dura-
tion of about one second. Then the SKIM sends mes-
sages to the instrument cluster circuitry to turn the
lamp on or off based upon the results of the SKIS
self-tests. If the SKIS indicator lamp comes on and
stays on after the bulb test, it indicates that the
SKIM has detected a system malfunction and/or that
the SKIS has become inoperative. If the SKIM
detects an invalid key when the ignition switch is
turned to the On position, it sends messages to the
instrument cluster to flash the SKIS indicator lamp.
The SKIM can also send messages to the instru-
ment cluster to flash the lamp and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Smart Key Immobilizer System Transponder Pro-
gramming in this group for more information on the
ªCustomer Learnº programming mode.
The SKIS indicator lamp uses a replaceable incan-
descent bulb and bulb holder on the instrument clus-
ter electronic circuit board. Refer to Group 8E -
Instrument Panel Systems for diagnosis and service
of a faulty SKIS indicator lamp. If the SKIS indicator
lamp comes on and stays on after the bulb test func-
tion, diagnosis of the SKIS should be performed with
a DRB scan tool and the proper Diagnostic Proce-
dures manual.
