I had a similar problem with my '94. Try disconnecting the battery, wait 30 seconds and reconnect the battery. This should reset the alarm.

DESCRIPTION

VEHICLE THEFT SECURITY SYSTEM

The Vehicle Theft Security System (VTSS) is designed to protect against whole vehicle theft. The system monitors vehicle doors, and ignition action for unauthorized operation.
The alarm activates:
  • Sounding of the horn
  • Flashing of the headlamps/park/tail lamps
  • An engine kill feature (with SKIS)

SENTRY KEY IMMOBILIZER SYSTEM

The Sentry Key Immobilizer System (SKIS) is designed to provide passive protection against unauthorized vehicle use by disabling the engine, after two (2) seconds of running, whenever an invalid key is used to start the vehicle. The SKIS is active whenever the ignition is on and does not require any customer intervention. The primary components of the system are the Sentry Key Remote Entry Module (SKREEM), Sentry Key (ignition key with a transponder molded into the head), indicator light, Body Control Module (BCM), and the Next Generation Controller (NGC). The SKREEM is mounted on the ignition switch/lock cylinder assembly with the molded, integral antenna mounted around the ignition housing. The indicator light, is located instrument panel switch pod, just to the right of the instrument cluster.
Electrical • Vehicle Theft Security • Operation Report a problem with this article

OPERATION

VEHICLE THEFT SECURITY SYSTEM

Upon failure of proper SKREEM communication to the Next Generation Controller (NGC), the NGC will shut off fuel after two seconds of run time. The engine will not re-crank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again. After six consecutive fuel shut-offs, the engine will no longer crank on subsequent key cycles. The failure must be corrected and a valid communication process between the SKREEM and the NGC must occur for the engine to crank and start again.
The electronics for the VTSS are part of the Body Control Module (BCM). The system is armed when the vehicle is locked using the:
  • Power door lock switches (with any door ajar)
  • Remote Keyless Entry transmitter.
  • Door Cylinder Lock Switches.
For vehicles equipped with SKIS, the doors do not have to be locked to enable the fuel shut off feature.
After the vehicle is locked and the last door is closed, the set LED indicator in the instrument panel switch pod will flash quickly for 16 seconds, indicating that arming is in progress. If no monitored systems are activated during this period, the system will arm and the LED will flash at a .5 Hertz (Hz) rate. If the liftgate is open, the LED will change its flash rate.
This indicates that the system is armed. If fault is detected on the driver key cylinder input, the indicator LED will remain solid during the arming process, although the system will still arm. If the indicator LED does not illuminate at all upon door closing it indicates that the system is not arming.
Passive disarming occurs upon normal vehicle entry by unlocking either door with the ignition key/remote transmitter. This disarming will also halt the alarm once it has been activated.
A tamper alert exists to notify the driver that the VTSS had been activated. This alert consists of 3 horn pulses when the vehicle is disarmed.
NOTE: The VTSS will not arm by pushing down the door lock mechanism. This will manually override the system.
For Door Cylinder Lock Switch service, (Refer to 8 - ELECTRICAL/POWER LOCKS/DOOR CYLINDER LOCK/UNLOCK SWITCH - REMOVAL).
If the VTSS is triggered, the horn will pulse, headlamps/marker lamps will flash, and the VTSS warning lamp will flash. If BCM determines the threat to be false and the VTSS is not triggered again, the system will shut down and rearm itself after three minutes. If a trigger is still active, the alarm will continue for an additional 15 minutes without the horn. The VTSS monitors the passenger compartment.
NOTE: System will not arm if passenger compartment is not secure.

ARMING THE VTSS - METHOD A

  1. With the key removed from the ignition lock and any door open (excluding liftgate), actuate one of the following:
  • Power door lock button to LOCK,
  • Key fob LOCK button
  • Driver door lock key cylinder to locked position.
  • Close all opened doors. Liftgate can remain open.
  • After the last door is closed, an arming time-out period of sixteen seconds will start, then the VTSS will become armed.

    ARMING THE VTSS - METHOD B

    Actuating the key fob transmitter LOCK button, key locking the front doors with the doors closed and the ignition locked will begin the arming time-out period. If method A, 16 second time-out sequence was in process when method B was actuated, the 16 second time-out will restart from the time of the second actuation.
    If the security lamp does not illuminate at all upon final door closure, it indicates that the system is not arming.
    The current VTSS status armed or disarmed shall be maintained in memory to prevent battery disconnects from disarming the system.

    TRIGGERING THE VTSS

    After the VTSS is armed, the following actions will trigger the alarm:
    • Opening any door (excluding liftgate).
    • Turning the ignition to the RUN position.
  • NOTE: When the VTSS is ARMED, the interior power door lock switch ?UNLOCK? will be disabled until the vehicle is disarmed.
    CAUTION: The VTSS indicator LED will trigger and engine will continue to run if the vehicle is equipped with SKIS and the proper key is used to start the vehicle. This condition will occur if the VTSS has been triggered. If valid key is used, VTSS will disarm.

    CENTRAL LOCKING/UNLOCKING

    This vehicle theft security system feature allows you lock all the doors with the key by using the drivers door lock cylinder.
    All vehicle doors and liftgate are locked with the first turn of the key to the LOCK position from the drivers door. A double activation feature of central unlocking requires you to turn the key in the door lock cylinder to the unlock position two times within two seconds to UNLOCK all vehicle doors at once.
    The first turn of the key in the door lock cylinder will disarm the system (the driver door cylinder lock switch connected to the back of the driver door lock cylinder) and unlock your drivers door. The second actuation within two seconds will then unlock all doors and the liftgate.

    SENTRY KEY IMMOBILIZER SYSTEM

    The SKIS includes keys from the factory which are pre-programmed. Each SKIM will recognize a maximum of eight Sentry Keys. If the customer would like to own additional keys other than those provided with the vehicle, they can be purchased from any authorized dealer. These keys must be programmed to the SKREEM on the vehicle in order for the system to recognize them as valid keys. This can be done by the dealer with a DRB III® scan tool or by a customer if this feature is available in their market and they have two (2) valid keys already available to them. 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's can be retrieved using a DRB III® scan tool as described in the appropriate Body Diagnostic Procedures manual.
    With the light being on there is a code stored in the computer that controls anti-theft , Your best bet would be to take your vehicle to the dealer !

    How do I turn off the alarm on my 2002 jeep wrangler tj?


    is this just alarm , and or the immoblizer SKIM problems, why not post the symptoms, or if opr guide missing.
    all answers USA spec cars......
    all answers STOCK cars, not hacked or with non Jeep parts.

    the SKIM can not be defeated.
    if still stock is it? with stock alarm. is it?

    the fsm is free for 02 TJ
    http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

    it explains all there. (no chapter on alarm only the IMMO )
    chapter 8Q
    theft and security chapter.
    I attempt to guess your question, how to disable just the door alarms. (not SKIM)

    my 02 TJ has no such thing, door alarms at all , mine had rag windows
    and and no electric door locks at all, just a key. (mech lock)
    not only that, the 02 operators guide has not a word at all about any alarm. period (USA cars)

    my 08 JK however has doors with glass windows and all trimmings.
    the alarm on my 08 is disabled by these steps.

    To Disarm the System
    To disarm the system, you will need to press the UNLOCK
    button on the RKE transmitter, or turn the ignition
    key to the ON position. If something has triggered the
    system in your absence, the horn will sound three times
    when you unlock the doors. Check the vehicle for tampering.
    The Security Alarm System is designed to protect your
    vehicle; however, you can create conditions where the
    system will arm unexpectedly. If you remain in the
    vehicle and lock the doors with the RKE transmitter, once
    the system is armed (after 16 seconds), when you pull the
    door handle to exit, the alarm will sound. If this occurs,
    press the UNLOCK button on the RKE transmitter to
    disarm the system. You may also accidentally disarm the
    system by unlocking the driver's door with the key and
    then locking it. The door will be locked but the Security
    Alarm will not arm.

    Here is information on disarming the alarm! First you need to know if it is a factor or after market system! Here is how you tell if the headlights are flashing, the alarm system is factory installed. Inserting the key into the driver door lock and turning to the left then back to the right is supposed to disarm it. If the parking lights are blinking,, the alarm is an aftermarket add on, and there should be a disarm button under the dash on the driver side. If it' an aftermarket alarm, you should be able to have it removed. There is a way to bypass the factory alarm. There is a wiring harness in the driver's door. You will have to remove the door panel to find it. The wire is dark green and purple. Splice into that wire and ground it to the chassis and the alarm should no longer work

    How doyou disarm the factory alarm system in a 1994 jeep grand cherokee my alarm system keeps shutting down the whole car it is a real pain to get it started again i just want to totally shut the alarm...


    The security alarm system on the 1994 Jeep Cherokee arms itself on any normal exit from the vehicle, i.e. ignition off, open door, lock door with power door locks, close door. If the doors are locked with the key, it does not arm.
    If the battery is disconnected, then reconnected, the alarm system will go into powerup alarm mode. The lights will flash, but the horn will not blow.
    The alarms can be disarmed by a keyless vehicle remote or by unlocking either of the front doors or the read lift gate with the key. If the key method does not work with any of those three entrances, there is a problem either with the input to the alarm module or the module itself.
    There is a switch in both front doors and the tailgate which is activated by manualy unlocking those doors. The alarms can be disabled by permanently grounding the wire going from either of those switches to the alarm module, but this will remove all theft protection.
    The best thing to do is to find out why the system is going off in the first place. It could just be a glitch, a loose connection that can be fixed fairly easily and keep your theft protection intact.

    Locking mechanism is broken on driver's door.


    If the valet key is not programmed to the Immobilzer system, it should start the car, but it will shut off. This is only if the car has an Immobilizer system. If your locksmith unlocked the car without the door key, then use the key to unlock and disarm the alarm in the door. If you triggered the alarm, the starter will be disabled till a unlock signal from a remote or the door is actually unlocked with a key. If that cannot be done, your only solution right now is to tow it to the dealership and have them make a master key and check the door locks for proper lock/unlock commands so the alarm will arm and disarm correctly.

    How can I reset my Factory Alarm on my Jeep it wont run


    Alarm Module Reset Procedure
    NOTE: This information applies to a Vehicle Theft Security System (VTSS) that was armed when the battery was disconnected and reconnected.
    When the armed VTSS senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed following a battery reconnection.
    The power-up mode will also apply if the battery goes dead while the system is armed and battery jump-starting is attempted. The engine no-run feature will prevent the engine from starting until the alarm system has been actively or passively disarmed.
    Passive disarming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the lift gate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter.
    Once the alarm has been activated (horn sounding, lights flashing, and the engine no-run feature), either disarming method will deactivate the alarm.
    Depressing the Panic button (if equipped) on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. The horn and lights can be stopped by pressing any of the RKE transmitter's buttons or driving the vehicle above 15 mph.
