Question about 2005 Audi A8

Open Question

Passive key door lock and unlock

After parking my A8-L (05) for a week at the airport the passive key door lock and unlock feature no longer works- How can it be reset? I left the valet key with the car.
The owners manual mentions that the car will automatically turn off certain features after a couple of days on non use- to conserve battery power- nothing mentions how to turn them back on- or should it happen automatically?

    What will happen as the battery recharges it will regenerate some of the control systems, When you say passive, do you mean keyless entry, or remote locking

SOURCE: remote central locking not working

As far as the central locking issue, it sounds like you need to replace your central locking pump. You can buy them online.
I have a 95 A6 and I am in the process of looking for a new central locking pump.
The part number may be 4A0 862 257 J, that is what it is for me.
There are directions online as to how to change this yourself once you get the part. If you buy from the dealership the part is $500.
Be thankful your child locks weren't engaged. We haven't been able to open our back doors since the pump went out.

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

Sounds like you are having problems with your built-in alarm system. Like most systems in your Audi, you can read the error codes stored in the controllers. It takes a tool normally only a dealer has (VW or Audi) or an adapter like the VAG Com. (Google it)

I also think you can disable the alarm system and just use the key.

Could the lock button on your remote be stuck? Use a different key/remote. (leaving the suspect key at home.) The keys/remotes can be taken apart....

Electrical • Vehicle Theft Security • Description Report a problem with this article

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 reset the ProLock system?


    Hi Carol , do you mean PATS passive antitheft system ? Locked up your car ,do you mean it won't crank over an start ?
    The passive anti-theft system uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.
    • During each vehicle start sequence, the ignition key identification code is requested by the vehicle protection anti-theft electronics.
    • If the key's ID code has been programmed into the system, the powertrain control module (PCM) (12A650) is signaled to enable the vehicle to start.
    • If the key's ID code is not programmed into the system, or if no encoded key is detected, then the powertrain control module is signaled to disable the vehicle.
    The passive anti-theft system communicates the state of the security system to the powertrain control module via the J-1850 communications network data link connector (DLC). The powertrain control modulebased on the communications from the passive anti-theft system, will determine if the vehicle's engine is enabled to start. The passive anti-theft system differs from the active anti-theft alarm system in that the passive anti-theft system enables/disables the vehicle from starting and only operates with the ignition switch in RUN/START position. The active anti-theft alarm system has perimeter protection capabilities and operates only with the ignition switch OFF. Refer to Section 13-11A for active anti-theft alarm system information.
    Vehicle Disabling The passive anti-theft system will be activated and disable the vehicle from starting if any of the following conditions exist:
    • damaged encoded key
    • unprogrammed key
    • non-encoded key (key has no electronics)
    • wiring concern
    • transceiver concern
    • Passive Anti-Theft System (PATS) control module concern
    • J-1850 Communications Network concern
    • Powertrain Control Module (PCM)

    I used csorb's instructions to reprogram a master key for my 2000 Lexus RX300. The ignition works perfectly, but the doors don't lock or unlock.


    Hi!!
    I believe your alarm is in the PASSIVE MODE, here is how it works.

    PASSIVE MODE Setting (Arming) Anti-Theft System The system will automatically set 30 seconds after following methods are performed: Remove ignition key from ignition switch. Exit vehicle, and close all doors. After performing this, anti-theft indicator on left side of instrument panel will light continuously for about 30 seconds. After 30 seconds, anti-theft indicator will blink once per second. When system is set, doors cannot be locked or unlocked using door lock control switch.
    CANCELING THE ALARM AND REPROGRAMING MAY SOLVE YOUR PROBLEM.
    Canceling Anti-Theft System Setting (No Alarm) When system is set (armed), but alarm is not sounding, use one of following methods to cancel system setting:
    • Unlock left or right front door using key.
    • Unlock all doors using remote keyless entry system.
    • Insert key in ignition switch and turn to ON position (this is operative only when anti-theft system has not been triggered).
    HERE IS HOW TO REPROGRAM THE ALARM IN CASE YOU NEED TO RESET IT.
    PROGRAMMING
    PASSIVE MODE NOTE:Initial mode is passive mode off. If there is a different signal in middle of programming, signal is invalid.
    Programming Passive Mode Off
    • Remove ignition key from ignition key cylinder. Ensure all doors (including back door) and engine hood are closed and unlocked. Perform all of following methods within 30 seconds:
    • Lock or unlock any door with key or remote keyless entry system.
    • Open driver door.
    • Lock and unlock driver door lock knob 3 times.
    • After performing this, system should start force lock after 2 seconds. Perform all of following methods within 20 seconds:
    • Unlock driver door lock knob.
    • Close and open driver door 2 times.
    • Lock and unlock driver door lock knob.
    • After performing this, system should start force lock after 2 seconds. Passive mode should now be off.
    Programming Passive Mode On
    • Remove ignition key from key cylinder. Ensure all doors, engine hood and luggage compartment door are closed and unlocked. Perform all of following methods within 30 seconds:
    • Lock or unlock any door with key or remote keyless entry system.
    • Open driver door.
    • Lock and unlock driver door lock knob 3 times.
    • After performing this, system should start force lock after 2 seconds. Perform all of following methods within 20 seconds:
    • Unlock driver door lock knob.
    • Close and open driver door 4 times.
    • Lock and unlock driver door lock knob.
    • After performing this, system should start force lock after 2 seconds. Passive mode should now be on.

    Starting System
    The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
    The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
    Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
    Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
    ------------------------------------------------------------------------------
    The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
    The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
    Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
    System Arming
    The system will be armed by the remote entry transmitter when the following input sequence is followed:
    1. Turn the ignition switch off and remove the key.
    1. Close all doors (unlocked).
    1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
    1. Wait for the anti - theft warning lamp to turn off.
    The system will also be armed when the following input sequence is followed:
    1. Turn the ignition switch off and remove the key.
    1. Open a door. Alarm warning lamp will flash.
    1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.
    1. Close all doors.
    1. Wait for the anti - theft warning lamp to turn off.
    Opening any door will activate the alarm after the alarm is armed.
    Disarming an Untriggered System
    The system can be disarmed by performing one of the following procedures.
    • Driver or RH front door is unlocked with a key.
    • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
    • If remaining in the vehicle, turn the ignition switch to ON or ACC position.
    System Triggering
    The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
    Disarming a Triggered System
    Carry out either of the following steps will disarm the triggered alarm system.
    • Driver or RH front door is unlocked with a key.
    • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
    Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
    --------------------------------------------------------------------
    Passive Anti-Theft System (PATS)
    The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
    The PATS functionality is incorporated within the powertrain control module.
    PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
    The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
    Anti-Theft Indicator
    Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
    The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
    For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

    This is an indication the passive reciever has been set to off. Press and hold the door button on the hand held passive remote for 2 seconds the door locks should cycle locked then unlocked. The passive indicator should go out and the system should see the remote when you walk away from the car (dors lock, horn blows).

    How do i reset my alarm on a 97 jeep Grand


    Here is excerpt from the 1998 Jeep Grand Cherokee Service Manual ... i know you posted under 1997 JGC but this information may be helpful ... by "reset alarm" i believe you meant disarming the alarm?

    Arming
    Passive arming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is exited with the key removed from the ignition switch, the headlamps are turned off, and the doors are locked using power lock switch. The power lock switch will not function if the key is in the ignition switch or the headlamps are on with the driver’s door open. The VTSS will not arm if either front door or the liftgate are locked using the key in the lock cylinder.
    Active arming of the VTSS occurs when the Remote Keyless Entry (RKE) transmitter is used to lock the vehicle, even if the doors and/or the liftgate are open when the RKE transmitter Lock button is depressed. However, the VTSS arming will not be complete until all the doors and the liftgate are closed.
    Following successful passive or active VTSS arming, the VTSS set lamp on the top of the instrument panel will flash rapidly for about 15 seconds after the illuminated entry system times out. This indicates that the VTSS arming is in progress. If the light stays on steadily during the arming, it indicates that the hood switch is closed (the hood is open). The VTSS will still arm if the hood is open, but the engine compartment will not be protected. Once the 15 second arming function is complete, the set lamp will flash at a slower rate to indicate that the VTSS is armed. Disarming Passive disarming of the Vehicle Theft Security Sytem (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the liftgate. 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, exterior lights flashing, and the the engine no-run feature), either disarming method will also deactivate the alarm. Depressing the Panic button on the RKE transmitter will also disarm the VTSS, but the horm will sound and teh exterior lamps will flash for about three minutes as a part of the Panic feature function. ..." And as an additional note, if you have the courtesy interior lights set at 30 seconds like i do, you have to wait until lights go out (with alarm still sounding) before you can disarm the alarm via passive disarm method... what a pain when you don't have the actual RKE handy... Good Luck!
