RE: How do i reset the auto lock feature
Here is what I have for my 02 service manual - maybe this will help you?
After reading all this looks like you would need the DRB IIIt programming tool.
VEHICLE THEFT SECURITY
DESCRIPTION
The Vehicle Theft/Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors the vehicle doors and ignition for
unauthorized operation.
The VTSS activates:
² Sounding of the horn
² Flashing of the park lamps
² Flashing of the head lamps
The Remote Keyless Entry (RKE) has 1 mode of
operation, CUSTOMER USAGEmode. The customer
usage mode provides full functionality of the module
and is the mode in which the RKE module should be
operating when used by the customer.
SENTRY KEY IMMOBILIZER SYSTEM (SKIS)
The Sentry Key Immobilizer System (SKIS) is
designed to provide passive protection against unauthorized
vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Sentry Key Immobilizer
Module (SKIM), the Sentry Key transponder,
the Vehicle Theft/Security System (VTSS) indicator
LED, and the Powertrain Control Module (PCM).
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 ignition
key. The VTSS indicator LED is located in the
instrument cluster.
The SKIS includes two valid Sentry Key transponders
from the factory. This is so the customer can self
program new keys if one is lost. If the customer
wishes, additional non-coded blank Sentry Keys are
available. These blank keys can be cut to match a
valid ignition key, but the engine will not start
unless the key transponder is also programmed to
the vehicle. The SKIS will recognize no more than
eight valid Sentry Key transponders at any one time.
The SKIS performs a self-test each time the ignition
switch is turned to the ON position, and will
store Diagnostic Trouble Codes (DTC’s) if a system
malfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRBlllt
scan tool as described in the proper Body Diagnostic
Procedures Manual.
DESCRIPTION
The Sentry Key Immobilizer Module (SKIM) contains
a Radio Frequency (RF) transceiver and a central
processing unit, which includes the Sentry 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 Sentry Key
transponders. The SKIS programming also enables
the SKIM to communicate over the Programmable
Communication Interface (PCI) bus network with the
Powertrain Control Module (PCM), and/or the DRB
IIIt scan tool.
OPERATION
When in the Customer Usage mode of operation,
the system is armed when the vehicle is locked using
the:
² Power Door Lock Switches
² Remote Keyless Entry (RKE) Transmitter
² Key Cylinder Switches
After the vehicle is locked and the last door is
closed, the VTSS indicator in the instrument cluster
will flash quickly for 16 seconds, indicating that the
arming is in process. After 16 seconds, the LED will
continue to flash at a slower rate indicating that the
system is armed.
VTSS disarming occurs upon normal vehicle entry
by unlocking either door via the key cylinder or RKE
transmitter, or by starting the vehicle with a valid
Sentry Key. This disarming will also halt the alarm
once it has been activated.
A tamper alert exists to notify the driver that the
system has been activated. This alert consists of 3
horn pulses and the security telltail flashing for 30
seconds when the vehicle is disarmed. The tamper
alert will not occur if disarmed while alarming.
The VTSS will not arm by mechanically locking the
vehicle doors. This will manually override the system.
OPERATION
The SKIS includes two valid Sentry Key transponders
from the factory. These two Sentry Keys can be
used to program additional non-coded blank Sentry
Keys. These blank keys can be cut to match a valid
ignition key, but the engine will not start unless the
key transponder is also programmed to the vehicle.
The SKIS will recognize no more than eight valid
Sentry Key transponders at any one time.
The SKIS performs a self-test each time the ignition
switch is turned to the ON position, and will
store Diagnostic Trouble Codes (DTC’s) if a system
malfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRB
IIIt scan tool as described in the proper Powertrain
Diagnostic Procedures manual.
OPERATION
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 housing.
This antenna ring must be located within eight
millimeters (0.31 inches) of the Sentry Key in order
to ensure proper RF communication between the
SKIM and the Sentry Key transponder.
For added system security, each SKIM is programmed
with a unique “Secret Key” code and a
security code. The SKIM keeps the “Secret Key” code
in memory. The SKIM also sends the “Secret Key”
code to each of the programmed Sentry Key transponders.
The security code is used by the assembly
plant to 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
Identification Number (VIN), which it learns through
a PCI bus message from the PCM during initialization.
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 security
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 Sentry Key transponder. The SKIM then
listens for a return RF signal from the transponder
of the Sentry Key that is inserted in the ignition lock
cylinder. If the SKIM receives an RF signal with
valid “Secret Key” and transponder identification
codes, the SKIM sends a “valid key” message to the
PCM over the PCI bus. If the SKIM receives an
invalid RF signal or no response, it sends “invalid
key” 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 which controls the VTSS indicator. The
SKIM sends messages to the Instrument Cluster to
turn the indicator 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 indicator off
for a duration of about one second. Then the SKIM
sends messages to turn the indicator on or off based
upon the results of the SKIS self-tests. If the VTSS
indicator 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 flash the VTSS indicator. The SKIM can
also send messages to flash the indicator to serve as
an indication to the customer that the SKIS has been
placed in its “Customer Learn” programming mode.
See Sentry Key Immobilizer System Transponder
Programming in this section for more information on
the “Customer Learn” programming mode.
For diagnosis or initialization of the SKIM and the
PCM, a DRB IIIt scan tool and the proper Powertrain
Diagnostic Procedures manual are required.
The SKIM cannot be repaired and, if faulty or damaged,
the unit must be replaced.
DIAGNOSIS AND TESTING
VEHICLE THEFT SECURITY SYSTEM
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS,
REFER TO RESTRAINT SYSTEMS BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
NOTE: The most reliable, efficient, and accurate
means to diagnose the Vehicle Theft Security System
(VTSS) and Sentry Key Immobilizer System
(SKIS) involves the use of a DRB lllT scan tool and
the proper Powertrain Diagnostic Procedures manual.
The Vehicle Theft Security System (VTSS), Sentry
Key Immobilizer System (SKIS) and the Programmable
Communication Interface (PCI) bus network
should be diagnosed using a DRB lllt scan tool. The
DRB lllt will allow confirmation that the PCI bus is
functional, that the Sentry Key Immobilizer Module
(SKIM) is placing the proper messages on the PCI
bus, and that the Powertrain Control Module (PCM)
and the Instrument Cluster are receiving the PCI
bus messages. Refer to the proper Powertrain or
Body Diagnostic Procedures manual.
Visually inspect the related wiring harness connectors.
Look for broken, bent, pushed out or corroded
terminals. If any of the conditions are present, repair
as necessary. Refer to Wiring Diagrams for complete
circuit descriptions and diagrams. Refer to (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/
SENTRY KEY IMMOBILIZER MODULE -
REMOVAL) for SKIM replacement.
STANDARD PROCEDURE
CONFIGURING A NEW MODULE / SWITCH
OPERATING MODES
To configure a new module or to switch operating
modes, a DRB lllt scan tool must be used.
(1) Hook up the DRB lllt scan tool to the Data
Link Connector (DLC).
(2) With the key in the ignition, turn the key to
the RUN position.
(3) After the DRB lllt scan tool initialization, perform
the following:
(a) Select “Theft Alarm.”
(b) Select “VTSS.”
(c) Select “Miscellaneous.”
(4) Once in the “Miscellaneous” screen:
(a) If you wish to configure a new module, select
“Configure Module.”
(b) If you wish to put the module into customer
usage mode, select “Enable VTSS.”
(c) If you wish to put the module into dealer lot
mode, select “Dealer Lot.”
SENTRY KEY IMMOBILIZER SYSTEM
INITIALIZATION
The Sentry Key Immobilizer System (SKIS) initialization
should be performed following a Sentry Key
Immobilizer Module (SKIM) replacement.
It can be summarized by the following:
(1) Obtain the vehicles unique PIN number
assigned to it’s original SKIM from the vehicle
owner, the vehicle’s invoice or from Chrysler’s Customer
Center.
(2) With the DRB lllt scan tool, select “Theft
Alarm,” “SKIM,” Miscellaneous.” Select “SKIM Module
Replaced” function and the DRB lllt will prompt
you through the following steps.
(3) Enter secured access mode using the unique
four digit PIN number.
(4) Program the vehicle’s VIN number into the
SKIM’s memory.
(5) Program the country code into the SKIM’s
memory (U.S.).
(6) Transfer the vehicle’s unique Secret Key data
from the PCM. This process will require the SKIM to
be in secured access mode. The PIN number must
be entered into the DRB lllt before the SKIM will
enter secured access mode. Once secured access
mode is active, the SKIM will remain in that mode
for 60 seconds.
(7) Program all customer keys into the SKIM’s
memory. This required that the SKIM be in secured
access mode The SKIM will immediately exit
secured access mode after each key is programmed.
NOTE: If a PCM is replaced, the unique “Secret
Key” data must be transferred from the SKIM to the
PCM. This procedure requires the SKIM to be
placed in SECURED ACCESS MODE using the four
digit PIN code.
SENTRY KEY IMMOBILIZER SYSTEM
TRANSPONDER PROGRAMMING
Two programmed Sentry Key transponders are
included with the Sentry Key Immobilizer System
(SKIS) when it is shipped from the factory. The Sentry
Key Immobilizer Module (SKIM) can be programmed
to recognize up to six additional
transponders, for a total of eight Sentry Keys. The
following “Customer Learn” programming procedure
for the programming of additional transponders
requires access to at least two of the valid Sentry
Keys. If two valid Sentry Keys are not available, Sentry
Key programming will require the use of a
DRBlllt scan tool.
CUSTOMER LEARN PROGRAMMING
(1) Obtain the additional Sentry Key transponder
blank(s) that are to be programmed for the vehicle.
Cut the additional Sentry Key transponder blanks to
match the ignition lock cylinder mechanical key
codes.
(2) Insert one of the two valid Sentry Key transponders
into the ignition switch and turn the ignition
switch to the ON position.
(3) After the ignition switch has been in the ON
position for about three seconds, but no more than
fifteen seconds, cycle the ignition switch back to the
OFF position. Replace the first valid Sentry Key in
the ignition lock cylinder with the second valid Sentry
Key and turn the ignition switch back to the ON
position. Both operations must be performed within
15 seconds.
(4) In approximately ten seconds the VTSS indicator
LED will start to flash to indicate that the system
has entered the “Customer Learn” programming
mode.
(5) Within approximately sixty seconds of entering
the “Customer Learn” programming mode, turn the
ignition switch to the OFF position, replace the valid
Sentry Key with a blank Sentry Key transponder,
and turn the ignition switch back to the ON position.
(6) In approximately ten seconds, the VTSS indicator
LED will stop flashing and stay on solid for
approximately three seconds and then turn OFF to
indicate that the blank Sentry Key transponder has
been successfully programmed. The SKIS will immediately
return to normal system operation following
exit from the “Customer Learn” programming mode.
(7) Repeat this process for each additional Sentry
Key transponder blank to be programmed.
If any of the above steps is not completed in the
proper sequence, or within the allotted time, the
SKIS will automatically exit the “Customer Learn”
programming mode. The SKIS will also automatically
exit the “Customer Learn” programming mode if it
sees a non-blank Sentry Key transponder when it
should see a blank, if it has already programmed
eight valid Sentry Keys, or if the ignition switch is
turned to the OFF position for more than about fifty
seconds.
NOTE: While in Customer Learn mode (LED flashing),
the engine will not START and RUN.
PROGRAMMING BLANK SENTRY KEY
TRANSPONDERS WITH A DRB lllT SCAN TOOL
When programming a blank Sentry Key transponder,
the key blank must first be cut to match the
ignition lock cylinder. It will also be necessary to
enter the vehicle’s four digit PIN code into the
DRBlllt scan tool to enter the Sentry Key Immobilizer
Module’s (SKIM’s) secured access mode.
NOTE: Once a Sentry Key is programmed to a particular
vehicle, it cannot be transferred to another
vehicle.
Insert the blank key into the ignition and turn it to
the RUN position. Using the DRBlllt scan tool, select
“Theft Alarm,” then “SKIM,” then “Miscellaneous.”
Select “Program New Key.” Enter the four digit PIN
code using the DRBlllt. When programming is completed,
the SKIM will exit secured access mode and
the DRBlllt will display the status of the key. One of
five different status messages may be displayed as
follows:
² “Programming Successful” is displayed if SKIM
Sentry Key programming succeeds.
² “Learned Key in Ignition” is displayed if the key
in the ignition has already been programmed into
that vehicle’s SKIM.
² “8 Keys Already Learned (At The Maximum)
Programming Not Done” is displayed if eight keys
have already been programmed into the SKIM. In
this case, if a new key needs to be added due to a
lost or defective key, the “Erase All Keys” function
(requires entering secured access mode) has to be
performed. Then the customer’s seven keys plus the
new key MUST be reprogrammed into the SKIM.
² “Programming Not Attempted” is displayed after
an “Erase All Keys” function is executed.
² “Programming Key Failed” is displayed if further
diagnosis is required.
² To learn additional keys, turn the ignition OFF,
remove the learned key, and insert the next new
blank key. Turn ignition to the RUN position and reenter
the secured access mode function and repeat
the “Program New Key” procedure outlined above.
SENTRY KEY IMMOBILIZER
SYSTEM INDICATOR LAMP
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses
the Vehicle Theft Security System (VTSS) indicator
in the instrument cluster to give an indication when
the SKIS is faulty or when the vehicle has been
immobilized due to the use of an invalid key. The
indicator is controlled by the instrument cluster
based upon messages received from the Sentry Key
Immobilizer Module (SKIM).
OPERATION
The SKIM sends PCI Bus messages to the instrument
cluster, to turn on the ’Security” indicator for
about 3 seconds when the ignition is turned to the
ON position, as a “Bulb” test. After completion of the
“Bulb” test, the SKIM sends a PCI bus messages to
keep the LED off for 1 second. Then the SKIM sends
messages to the instrument cluster to turn the LED
off based upon the results if the SKIS self - test. If
the indicator illuminates and remains illuminated
after the “bulb test”, it indicates that the SKIM has
detected a system malfunction and/or the system has
become inoperative. If the SKIM detects a invalid
key when the ignition switch is turned on, it sends a
message to the instrument cluster to flash the “Security”
indicator.
The SKIM can also send messages to the cluster to
flash the LED and generate a chime. These functions
serve as an indication to the customer that the SKIM
is in the Customer Learn programming mode. See
Sentry Key Immobilizer System Transponder Programming
in this group for more information on the
“Customer Learn” programming Mode.
If the VTSS indicator remains on after the “Bulb”
test, the system should be diagnosed using the
DRBIIIt scan tool and the proper Powertrain Diagnostic
Procedures manual.
After reading all this looks like you would need the DRB IIIt programming tool.
VEHICLE THEFT SECURITY
DESCRIPTION
The Vehicle Theft/Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors the vehicle doors and ignition for
unauthorized operation.
The VTSS activates:
² Sounding of the horn
² Flashing of the park lamps
² Flashing of the head lamps
The Remote Keyless Entry (RKE) has 1 mode of
operation, CUSTOMER USAGEmode. The customer
usage mode provides full functionality of the module
and is the mode in which the RKE module should be
operating when used by the customer.
SENTRY KEY IMMOBILIZER SYSTEM (SKIS)
The Sentry Key Immobilizer System (SKIS) is
designed to provide passive protection against unauthorized
vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Sentry Key Immobilizer
Module (SKIM), the Sentry Key transponder,
the Vehicle Theft/Security System (VTSS) indicator
LED, and the Powertrain Control Module (PCM).
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 ignition
key. The VTSS indicator LED is located in the
instrument cluster.
The SKIS includes two valid Sentry Key transponders
from the factory. This is so the customer can self
program new keys if one is lost. If the customer
wishes, additional non-coded blank Sentry Keys are
available. These blank keys can be cut to match a
valid ignition key, but the engine will not start
unless the key transponder is also programmed to
the vehicle. The SKIS will recognize no more than
eight valid Sentry Key transponders at any one time.
The SKIS performs a self-test each time the ignition
switch is turned to the ON position, and will
store Diagnostic Trouble Codes (DTC’s) if a system
malfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRBlllt
scan tool as described in the proper Body Diagnostic
Procedures Manual.
DESCRIPTION
The Sentry Key Immobilizer Module (SKIM) contains
a Radio Frequency (RF) transceiver and a central
processing unit, which includes the Sentry 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 Sentry Key
transponders. The SKIS programming also enables
the SKIM to communicate over the Programmable
Communication Interface (PCI) bus network with the
Powertrain Control Module (PCM), and/or the DRB
IIIt scan tool.
OPERATION
When in the Customer Usage mode of operation,
the system is armed when the vehicle is locked using
the:
² Power Door Lock Switches
² Remote Keyless Entry (RKE) Transmitter
² Key Cylinder Switches
After the vehicle is locked and the last door is
closed, the VTSS indicator in the instrument cluster
will flash quickly for 16 seconds, indicating that the
arming is in process. After 16 seconds, the LED will
continue to flash at a slower rate indicating that the
system is armed.
VTSS disarming occurs upon normal vehicle entry
by unlocking either door via the key cylinder or RKE
transmitter, or by starting the vehicle with a valid
Sentry Key. This disarming will also halt the alarm
once it has been activated.
A tamper alert exists to notify the driver that the
system has been activated. This alert consists of 3
horn pulses and the security telltail flashing for 30
seconds when the vehicle is disarmed. The tamper
alert will not occur if disarmed while alarming.
The VTSS will not arm by mechanically locking the
vehicle doors. This will manually override the system.
OPERATION
The SKIS includes two valid Sentry Key transponders
from the factory. These two Sentry Keys can be
used to program additional non-coded blank Sentry
Keys. These blank keys can be cut to match a valid
ignition key, but the engine will not start unless the
key transponder is also programmed to the vehicle.
The SKIS will recognize no more than eight valid
Sentry Key transponders at any one time.
The SKIS performs a self-test each time the ignition
switch is turned to the ON position, and will
store Diagnostic Trouble Codes (DTC’s) if a system
malfunction is detected. The SKIS can be diagnosed,
and any stored DTC can be retrieved using a DRB
IIIt scan tool as described in the proper Powertrain
Diagnostic Procedures manual.
OPERATION
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 housing.
This antenna ring must be located within eight
millimeters (0.31 inches) of the Sentry Key in order
to ensure proper RF communication between the
SKIM and the Sentry Key transponder.
For added system security, each SKIM is programmed
with a unique “Secret Key” code and a
security code. The SKIM keeps the “Secret Key” code
in memory. The SKIM also sends the “Secret Key”
code to each of the programmed Sentry Key transponders.
The security code is used by the assembly
plant to 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
Identification Number (VIN), which it learns through
a PCI bus message from the PCM during initialization.
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 security
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 Sentry Key transponder. The SKIM then
listens for a return RF signal from the transponder
of the Sentry Key that is inserted in the ignition lock
cylinder. If the SKIM receives an RF signal with
valid “Secret Key” and transponder identification
codes, the SKIM sends a “valid key” message to the
PCM over the PCI bus. If the SKIM receives an
invalid RF signal or no response, it sends “invalid
key” 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 which controls the VTSS indicator. The
SKIM sends messages to the Instrument Cluster to
turn the indicator 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 indicator off
for a duration of about one second. Then the SKIM
sends messages to turn the indicator on or off based
upon the results of the SKIS self-tests. If the VTSS
indicator 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 flash the VTSS indicator. The SKIM can
also send messages to flash the indicator to serve as
an indication to the customer that the SKIS has been
placed in its “Customer Learn” programming mode.
See Sentry Key Immobilizer System Transponder
Programming in this section for more information on
the “Customer Learn” programming mode.
For diagnosis or initialization of the SKIM and the
PCM, a DRB IIIt scan tool and the proper Powertrain
Diagnostic Procedures manual are required.
The SKIM cannot be repaired and, if faulty or damaged,
the unit must be replaced.

placed in SECURED ACCESS MODE using the four
digit PIN code.
SENTRY KEY IMMOBILIZER SYSTEM
TRANSPONDER PROGRAMMING
Two programmed Sentry Key transponders are
included with the Sentry Key Immobilizer System
(SKIS) when it is shipped from the factory. The Sentry
Key Immobilizer Module (SKIM) can be programmed
to recognize up to six additional
transponders, for a total of eight Sentry Keys. The
following “Customer Learn” programming procedure
for the programming of additional transponders
requires access to at least two of the valid Sentry
Keys. If two valid Sentry Keys are not available, Sentry
Key programming will require the use of a
DRBlllt scan tool.
CUSTOMER LEARN PROGRAMMING
(1) Obtain the additional Sentry Key transponder
blank(s) that are to be programmed for the vehicle.
Cut the additional Sentry Key transponder blanks to
match the ignition lock cylinder mechanical key
codes.
(2) Insert one of the two valid Sentry Key transponders
into the ignition switch and turn the ignition
switch to the ON position.
(3) After the ignition switch has been in the ON
position for about three seconds, but no more than
fifteen seconds, cycle the ignition switch back to the
OFF position. Replace the first valid Sentry Key in
the ignition lock cylinder with the second valid Sentry
Key and turn the ignition switch back to the ON
position. Both operations must be performed within
15 seconds.
(4) In approximately ten seconds the VTSS indicator
LED will start to flash to indicate that the system
has entered the “Customer Learn” programming
mode.
(5) Within approximately sixty seconds of entering
the “Customer Learn” programming mode, turn the
ignition switch to the OFF position, replace the valid
Sentry Key with a blank Sentry Key transponder,
and turn the ignition switch back to the ON position.
(6) In approximately ten seconds, the VTSS indicator
LED will stop flashing and stay on solid for
approximately three seconds and then turn OFF to
indicate that the blank Sentry Key transponder has
been successfully programmed. The SKIS will immediately
return to normal system operation following
exit from the “Customer Learn” programming mode.
(7) Repeat this process for each additional Sentry
Key transponder blank to be programmed.
If any of the above steps is not completed in the
proper sequence, or within the allotted time, the
SKIS will automatically exit the “Customer Learn”
programming mode. The SKIS will also automatically
exit the “Customer Learn” programming mode if it
sees a non-blank Sentry Key transponder when it
should see a blank, if it has already programmed
eight valid Sentry Keys, or if the ignition switch is
turned to the OFF position for more than about fifty
seconds.
NOTE: While in Customer Learn mode (LED flashing),
the engine will not START and RUN.
PROGRAMMING BLANK SENTRY KEY
TRANSPONDERS WITH A DRB lllT SCAN TOOL
When programming a blank Sentry Key transponder,
the key blank must first be cut to match the
ignition lock cylinder. It will also be necessary to
enter the vehicle’s four digit PIN code into the
DRBlllt scan tool to enter the Sentry Key Immobilizer
Module’s (SKIM’s) secured access mode.
NOTE: Once a Sentry Key is programmed to a particular
vehicle, it cannot be transferred to another
vehicle.
Insert the blank key into the ignition and turn it to
the RUN position. Using the DRBlllt scan tool, select
“Theft Alarm,” then “SKIM,” then “Miscellaneous.”
Select “Program New Key.” Enter the four digit PIN
code using the DRBlllt. When programming is completed,
the SKIM will exit secured access mode and
the DRBlllt will display the status of the key. One of
five different status messages may be displayed as
follows:
² “Programming Successful” is displayed if SKIM
Sentry Key programming succeeds.
² “Learned Key in Ignition” is displayed if the key
in the ignition has already been programmed into
that vehicle’s SKIM.
² “8 Keys Already Learned (At The Maximum)
Programming Not Done” is displayed if eight keys
have already been programmed into the SKIM. In
this case, if a new key needs to be added due to a
lost or defective key, the “Erase All Keys” function
(requires entering secured access mode) has to be
performed. Then the customer’s seven keys plus the
new key MUST be reprogrammed into the SKIM.
² “Programming Not Attempted” is displayed after
an “Erase All Keys” function is executed.
² “Programming Key Failed” is displayed if further
diagnosis is required.
² To learn additional keys, turn the ignition OFF,
remove the learned key, and insert the next new
blank key. Turn ignition to the RUN position and reenter
the secured access mode function and repeat
the “Program New Key” procedure outlined above.
SENTRY KEY IMMOBILIZER
SYSTEM INDICATOR LAMP
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses
the Vehicle Theft Security System (VTSS) indicator
in the instrument cluster to give an indication when
the SKIS is faulty or when the vehicle has been
immobilized due to the use of an invalid key. The
indicator is controlled by the instrument cluster
based upon messages received from the Sentry Key
Immobilizer Module (SKIM).
OPERATION
The SKIM sends PCI Bus messages to the instrument
cluster, to turn on the ’Security” indicator for
about 3 seconds when the ignition is turned to the
ON position, as a “Bulb” test. After completion of the
“Bulb” test, the SKIM sends a PCI bus messages to
keep the LED off for 1 second. Then the SKIM sends
messages to the instrument cluster to turn the LED
off based upon the results if the SKIS self - test. If
the indicator illuminates and remains illuminated
after the “bulb test”, it indicates that the SKIM has
detected a system malfunction and/or the system has
become inoperative. If the SKIM detects a invalid
key when the ignition switch is turned on, it sends a
message to the instrument cluster to flash the “Security”
indicator.
The SKIM can also send messages to the cluster to
flash the LED and generate a chime. These functions
serve as an indication to the customer that the SKIM
is in the Customer Learn programming mode. See
Sentry Key Immobilizer System Transponder Programming
in this group for more information on the
“Customer Learn” programming Mode.
If the VTSS indicator remains on after the “Bulb”
test, the system should be diagnosed using the
DRBIIIt scan tool and the proper Powertrain Diagnostic
Procedures manual.

What a wreck of an idea
My 2005 Neon has this problem with the Anti theft light on steady, engine won't start or even crank. I discovered if I ground the negative side of the Automatic Shutdown Relay the car will start and run okay except the alternator isn't charging the battery. But the jest of this fine explanation, whoever you are you know your anti theft stuff, the jest is I simply want to disable this thing so my car will run and charge the battery. Dodge garage couldn't get it corrected and I paid $68 today for them to tell me they have to start looking at wiring issues etc at $65 an hour. I've been looking at wiring all week and can't find anything. Thanks for the great explanation of this system I now have hope I will find the problem eventually.
