    My 2002 VW Golf TDI starts and stops a second or two later. The key-door light is flashing, and I was told by the service department that it is the immobilliser. The VW dealer is 2 hours away.

SOURCE: electronic immobilizer

The immobilizer isn't recognizing your key. You need to reprogram your keys to your car. Unless you know the SKC and know someone with VAG-COM you are going to have to go to the dealer.

Did you try all the different keys you have for the car? If you are lucky only one key is bad and you can drive to the dealer and get the bad key reprogrammed or buy a new key and have them program it to you car. Otherwise, you are going to have to get towed.

If it is just one key, make sure you bring all the keys to the dealer so they can do the reprogramming correctly.

Was any work being done on your car to cause this?

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

Need to override factory keyless entry wont start


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.

    Use the other spare key remote, if it starts it means your other key fob maybe bad or needs battery replaced. If it still does it then your immobilizer receiver is malfunctioning. That's if it is related to your immobilizer. Have it scanned for trouble codes (DTC), this way you won't be guessing and start replacing unrelated parts.

    My jetta won't recognize the key


    I have had this same issue ever since I purchased the car new in 2000. It seems to be a very intermittent issue, but I found that when it occurred, it was typically damp and between 40 and 50F.

    In any case, the dealer was not able to diagnose and fix the problem. I did get them to give me a 4 digit pass code for the immobilizer. This pass code is entered by using the clock adjust knob and the odometer reset button. Once the pass code is entered, the car will start. However, this is not a permanent fix as you may need to enter the pass code again should the immobilizer activate.

    Sometimes the Jetta will start after 5-6 trys when the immobilizer is activated, but if I crank anything past 10, I usually resort to the pass code.

    I am searching today for solutions since I have needed to use the pass code twice in the last 4 times that I have neede to start the car, and the weather is perfect.
