You should be able to use your key cylinder at your driver door to disarm the factory alarm by turning it to unlock 2 times with the key

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.



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.

There is a way of running it by putting the spare key in the ignition and turning the ignition on but dont start the car, put the second key in the drivers lock and turn as if you are opening it until you hear 2 beeps, then press the unlock button on the remote while in the door.The car should beep once and flash the indicator lights.Remove the door key and remove the ignition key then lock the car using the remote.Open the car and try the ignition.Some systems lose the memory of the key chip so this may help you but with technology it works for some and not for others.

Try and move the steering wheel around while you remove the key. It may have it locked in place.

Just happened to me in a 2006 VW Passat 2.0T - Automatic. You simply need to depress the brake and then press the button on the shift lever 3 times. You will then hear the key being released and you can pull it out.

you have activated your immobilizer. either you tried to start it with an uncoded key or the key itself has gone bad. head to dealership with car in tow if you cant start
