Question about Mercedes-Benz CL600

2 Answers

Locking system malfunction: electronic key lock/unlock function causes lights to flash and activates alarm, but doors will not lock and passenger door will not unlock. Only manual key works (but will not open locked trunk). Battery light in key flashes normally, so battery in key is probably OK; if not, how is key battery changed.

Depending on the remote, there may be a small screw holding it together, or it may just snap together. 

If you do not see a screw in the back (usually these are on aftermarket alarms and such), remove the key rink from the remote, Use a small flat-head screwdriver and gently pry the two sides apart. They should pop apart, and you will see the battery. Replace the battery and snap the remote back together (this may take a bit of pressure).

If you have trouble go to the dealer and ask someone in parts, or a service writer to show you how. They should not charge you for showing you how to do it!
---------------------------- in many cases you will see that still after replacing the battery in the key does not solve the problem.then in the key there is actually a chip.if that chip looses its charge then it needs recharging.the car service center charges $250 for just charging the chip in the key.but a professional locksmith is very helpfull if the chip needs charging ,as he will just charge under $75 for the same purpose which the service center charges $250.the locksmith have all the required programs and software to charge the chips. any of this two options should help you. 1)either the battery needs replacement  or  2)the chip in the key needs charging. thanks.please do rate the solution.keep updated.thank you for using fixya.

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



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)


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



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.
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.


  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.


    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.


    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.


    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.


    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 to set & cancel theft deterrent system or how to set & cancel security...

    Theft deterrent system (on some models)

    Theft deterrent system is designed to deter vehicle theft. The system flashes the turn signal lights and turns on the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn when it detects abnormalities such as follows:

    • Any door or hood is forcibly opened.
    • The batter terminal is disconnected and then reconnected
    • The system control is disconnected and then reconnected.
    • Abnormal impact is detected when the impact sensor function is on.

    The system flashes the turn signal lights and turns the interior light or the signal lights only (depending on the model), and sounds security horn and vehicle horn if someone attempts to damage or break into your car.

    Setting the system

    You can set the system with or without the impact sensor function. For details, see "Canceling the impact sensor" below.

    1. Turn the ignition key to "LOCK" and remove it.
    2. Have all passengers get out of the vehicle
    3. Push the lock (set) switch on the wireless remote control key once. At this time, the turn signal lights flashes once and the security indicator light comes on.

    The system is set after 30 seconds. At this time, the security indicator light start flashing slowly.

    Once the system is set, you cannot start the engine until you cancel the system.

    The system will not be set in the following cases.

    • When any of the door is open; security horn sounds for 1 second, close the door and set the system again.
    • When the hood is open; close the hood securely.

    Canceling the Impact Sensor

    The impact sensor can be cancelled to prevent false alarms from being triggered incase of the following conditions:

    • When parked in the noisy area
    • The vehicle body or glass is subjected to a strong impact from the (such as in highly pressurized car wash).
    • When transporting by a car carrier or ferry.

    To cancel the impact sensor;

    1. Lock the door by pushing the lock (set) switch on the wireless remote control key once, and turn signal light flash once
    2. Then push the lock (set) switch twice within 5 seconds. At this time, the turn signal flash 5 times to indicate the impact sensor function is disable.

    The impact sensor is deactivated as long as the system remained armed.

    Canceling the system

    The system will be cancelled by the following two ways:

    • Turn the ignition key from "LOCK" to "ON" position.
    • Unlock any of the doors by pushing the unlock (cancel) switch

    If the turn signal lights flash 3 times, the system has been alarmed. Check to see if there is any abnormality with your vehicle.

    If any of the doors is not opened within 30 seconds, all doors will be automatically locked and the system will be set.

    When the system is set

    Activating the system; When the system detects abnormalities such as follows, it flashes the turn signal lights and turns on the interior light or the turn lights only (depending on the model) and sounds the security horn and vehicle horn of 30 seconds.

    • Unlocking any door without using wireless control
    • Any door or hood is forcibly opened.
    • The battery terminal is disconnected and then reconnected.
    • The system control assembly is disconnected and then reconnected
    • Abnormal impact is detected when the impact sensor function is on.

    Reactivating the alarm;

    Once set, the system automatically resets the alarm after the alarm stops.

    The alarm will activate again under the same circumstances described in "Activating the system".

    Stopping the Alarm

    The alarm will be stopped by the following two ways;

    • Turn the ignition key from the "LOCK" to "ON" position.
    • Unlock any of the doors by pushing the unlock (cancel) switch.

    The system can be cancelled by these ways at the same time.

    If the battery becomes discharged due to the vehicle being unused, for a long time etc., when the battery is recharged or replaced, the system will activate the alarm. If this happens, immediately unlock any of the doors by pushing the unlock (cancel) switch, and the alarm will stop.

    Testing the system

    1. Set the system
    2. Insert a wireless remote control key into the key hole on the driver's door handle, and unlock the door.
    3. Open the door, and an alarm will sound.
    4. Stop the alarm by pushing the unlock (cancel) switch.
    5. Repeat this operation for the front passenger's door.

    Good luck.

    Where is the alarm system on 2005 lincoln ls?

    Anti-Theft - Perimeter The anti-theft perimeter protection feature is controlled by the front electronic module (FEM), the rear electronic module (REM), and the driver door module (DDM). The alarm can be armed using:
    • the LOCK button in the remote keyless entry (RKE) transmitter to the DDM, which sends a message through the standard corporate protocol (SCP) communications network to the FEM.
    • the driver or passenger door lock switch if the corresponding door is open when LOCK is actuated.
    • the key in the driver door lock cylinder.
    • the RKE keypad by pressing 7/8 and 9/0 simultaneously.
    The FEM and REM then monitor all features, which activate the alarm in the event of an unauthorized entry.
    The luggage compartment lid lock cylinder does not disarm the vehicle's perimeter alarm. The luggage compartment alarm can be temporarily inhibited through the luggage compartment lid disarm switch, located in the luggage compartment lock cylinder or by opening the lugguage compartment with the RKE transmitter or the RKE keypad. Once the luggage compartment lid closes, the perimeter alarm system immediately starts monitoring the luggage compartment. The perimeter alarm can only be disarmed:
    • by unlocking the vehicle using the RKE transmitter.
    • by unlocking the vehicle using the driver door lock cylinder switch.
    • by cycling to RUN a valid programmed key in the ignition switch.
    • by entering the correct vehicle unlock code on the RKE keypad.
    Additionally, an ignition switch tamper circuit and a signal hardwire line from the FEM to the REM are monitored.
    If any of the above features receive any activation once the alarm is armed, the alarm activates the visual and audible alerts. ......

    How do you reset the alarm on a 1999 toyota camry if i dont have the remote locking mechanisim

    Operation of the theft deterrent system is discussed in the 1999 Toyota Camry Owner's Manual beginningh on page 21. Unlocking the door with the key should disarm the alarm system. If it does not disarm when using the key, there are only two possibilities:

    > You have an aftermarket alarm system installed in addition to the system tht was provided by the manufacturer and they are interfering with each other.

    > OR

    > Your vehicle needs service to correct the malfunction.

    You might try unlocking the car from the passenger side or use the key to open the trunk first to see if this works. If it does, the switch inside the driver door is probably malfunctioning.

    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?

    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!

    I bought a new Keyless remote for a 2007 Forester from a Subaru Dealer to replace an original one that went bad after 2 years. I have followed the directions in the owner's manual to program it, but can't...

    IMPREZA: 2005, 2006, 2007 and
    FORESTER: 2005, 2006, 2007, 2008
    Check for Immobilizer key on Forester XT models only.
    information is always subject to change and correction imp05keylessremote1.jpg
    new remote for 2005 Imprezas.
    This is not the same remote as the 05 Legacy/Outback remote which also has truck/gate release on the front and a red panic button on the back.
    Lock: press Lock button for 2 seconds or so to lock car, and arm optional security system. The car with chirp once and turn signals flash for locked, 5 short chirps and signal flashes if any door is not fully closed. The dome light goes on for 15 seconds and ignition key ring (if present) will light for 30 seconds when unlocked.
    Unlock: press unlock one time for driver's door, press again within 5 seconds to unlock all doors inkling rear gate (wagon). The system does not open the trunk.
    Panic mode: press and hold lock button for approx. 3-4 seconds to activate Panic mode. I panic model the horn honks and turn signals flash until either the lock or unlock button is pushed again.
    Finder mode: Press lock button 3 times within 5 seconds to activate Vehicle Finder mode. The horn will honk once and the turn signals will flash 3 times
    Distance: works within approx. 30 feet depending on battery strength, nearby concrete walls and etc.
    Audible Chirp On-Off: the system will chirp when locked or unlocked. To turn OFF the chirps, unlock the door and then push both lock and unlock buttons at the exact same time for 2+ seconds. There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.
    Battery: as the battery ages it will only work as you get closer to the car. When a battery is replaced, the transmitter must be re-synchronized with the Keyless control unit. To synchronize, press the lock or unlock button 6 times.
    Programming: 4 codes may be programmed.
    Sit in driver's seat and unlock all doors. Open and close the driver's door
    Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
    You now have 45 seconds to complete the programming as below.
    Open and close driver's door again.
    Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
    To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
    Done programming? remove the key from the ignition and the horn will honk 3 times.
    DELETE old codes? Reprogram 4 times, it will overwrite old codes.
    Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
    There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
    You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
    Disarm the system: push unlock for 2 seconds
    Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!
    VALET mode: To set valet mode or just to disable the security alarm system: 1. unlock all doors 2. physically open the driver's door 3. hold the UNLOCK button on remote for 2+ seconds. The red 'security' light will then flash 2 times a second until the car is turned on.
    System has been Tripped (except for STi): if you unlock the door with the remote and it chirps the signal light flash 4 times, the system has been triggered;
    Identification mode: To find out what happened and why the system was triggered:
    Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
    Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

    Replaced the alternator, now anti theft won't disable

    The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
    Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
    The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
    The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
    The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
    The RAP module has three wire connectors attached to it:
    • The antenna for the keyless entry remote transmitter.
    • 26 circuit connector (C256).
    • 22 circuit connector (C257).
    In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
    The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered.
    Prearming and Arming the System
    The system can be armed if:
    • The ignition is OFF.
    • The PANIC alarm is OFF.
    • All doors are closed.
    There are two ways to prearm the system:
    • Press the LOCK button on the transmitter.
    • Open a door, press the power door lock button and close the door.
    After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds.
    Disarming an Untriggered System
    An armed system will be disarmed with one of these valid actions:
    1. Pressing the UNLOCK button on the transmitter.
    1. Placing a key in the door and turning to UNLOCK.
    1. Turning the key to RUN or ACC.
    The anti-theft alarm can be triggered by the following conditions:
    • The ignition cylinder is damaged with or without the RAP being armed.
    • A door is opened without disarming the armed RAP module.
    The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash.
    Disarming a Triggered System
    If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:
    1. Pressing the UNLOCK or PANIC button on the transmitter.
    1. Putting a key in the door and unlocking the door.
    1. Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).
