My starter won't turn over because of the immobilizer


It could be the neutral safety switch if it is an automatic trans.
On most cars you can disable the alarm by locking and unlocking the drivers door with the key.
A mechanic would check for voltage at the starter, the neutral safety switch or clutch switch, and the key switch.

2005 subaru outback immobilizer reset? Alarm was set with door being unlocked with key, immobilizer shut off all power. How can this be reset?


This could be a few things. If the security system was enabled and you just unlocked the door with a key and not using the remote, then all you have to do is put the key in the ignition and turn on/off three times. That's it!

Some cars have immobilizer keys. The immobilizer prevents unauthorized keys from starting the car (yours may or may not have it, depending on the exact Outback model).


Look here for the different styles of immobilizer keys:

Immobilizer active reset on 2006 volkswagon passat


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.

Immobilizer


If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.
