96 volvo 850 won't start and horn and turn signal chirp on and off


My wife ran into this problem one day when she came out of a store. Turns out the car alarm had been set off in her absence, and the alarm system had immobilized the car. The solution was to simply use the remote (rather than the key) to unlock the car. That cleared the immobilizer, and she started it up and drove off.

Vw beetle does not start. seems like its some kind of anti theft protection. the car/key icon lights up, it turns over for a second , then off. this is the first time this has happened, but we bought it...


First of all you need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.

  • Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!

    This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

    From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

    After changing the fan belt at a garage, my Mazda 6 would not start. We trried using the extra key remote, but the car still will not start. What is the problem/solution? Is there a special Security...


    Hi there,

    Your Mazda 6 keys have transponders built in and only the correct key I.D. will activate your vehicle's immobilizer.

    I'm at a loss as to how changing a fan belt could have altered your vehicle's immobilizer system - are you absolutely certain the garage hasn't disturbed any of the electronics?

    First, we need to establish whether your vehicle's immobilizer still considers your keys as valid.

    - Insert Key # 1 and turn ignition to ON (do not start).
    Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 1 is considered still vaild.
    - quickly turn Key 1 back to LOCK position and remove key.

    Wait 5 seconds...

    - Insert Key # 2 and turn ignition to ON (do not start).
    Observe the "Security" light in the cluster - it should illuminate, then turn off after approx. 3 seconds. If this works, then Key # 2 is considered still vaild.

    Note: if Security light does not behave as above and keys still won't start your car, then your keys are no longer validated by the PCM

    If this is the case, then unfortunately unlike other manufacturers, only Mazda will be able to re-program your key's ID into your vehicle's PCM. Contact your local Mazda Dealership to discuss.


    Regards,

    Scott

    I have a 2006 I280 iszuzu pickup the antitheft was engaged and won't start how do I fix it?


    MAKE SURE YOU USING THE RIGHT KEYS. TRY ANOTHER IGNITION KEY.PLACE KEY IN THE SWITCH. TURN IGNITION SWITCH TO ON POSITION UNTIL IMMOBILIZER WARNING LAMP ILLUMINATES FOR 2 TO 3 SECONDS. IF IMMOBILIZER WARNING LAMP ILLUMINATES FOR 2 TO 3 SECONDS THEN FLASHES RAPIDLY.KEY CODE NOT RECOGNIZED.REMOVE KEY AND TRY AGAIN. IF ALL FAILS TAKE CAR TO DEALERSHIP THEY HAVE TO USE DIAGNOSTIC EQUIPMENT TO FIX CAR.PROBLEM COULD BE IN THE IGNITION SWITCH,BCM,FAULT IN THE ECM OR IMMOBILIZER CODE INCORRECT.

    My '98 Ford Taurus won't start


    "Security" or Key-shaped light flashes on the dashboard ? Your car might be equipped with an immobilizer. (you can find more information about the immobilizer in your owner's manual). The immobilizer allows the engine to run only if the correct key is used. If your car has an immobilizer, you probably see a "Security" or Key-shaped light coming on on the dashboard every time you turn the ignition ON. If this light is flashing when you turn the ignition ON, it could mean that there is some problem with an immobilizer or the system does not recognize the key. If the immobilizer doesn't recognize the key, the engine wold not start at all, or would start and then die in few seconds.
    You can try a spare key, if it won't work, your dealer is the place to call. Sometimes, the key is just need to be reprogrammed.

    Bmw e36 immobilised, iginition lights come on, but the starter wont turn over. how do i start the car to get it to a garage, i dont wont to pay the £70 for recovery truck


    BMW E36 immobilizer Hope the following will help. Had similar problems. The transmitter buttons on keys is for central locking and alarm. Inside the key at the front there is a small electronic/magnetic chip that looks like a block. About 8mm long, 2mm deep and 4mm wide, not connected to any pc board. This is the immobilizer. It must match the receiver that is located behind the ignition switch. If it is loose and too far away from the receiver it won?t deactivate it. If you made a spare key it will switch on electrics but won?t start the car. If you don?t have an immobilizer chip any alarm shop will be able to program a new chip or install a new pair for your keys. There is a way to disable the immobilizer but rather have it fix and protect your car. I read an article somewhere (perhaps bmw e36 blog) of people removing this immobilizer. Good luck
