Based on what you write, I would say that since you disconnected the battery, you have effected the codes in your on board computer.

Your simplest and quickest fix would be to find a local independent foreign car shop and have them reset the code.

If you would like to contact me again about this or other problems, feel free to do so.

Have the remote starter and all its components checked. If necessary disconnected and then see if the problem persists. I think your culprit is the remote.

Chrysler Crossfire 2006 immobilizer?


You can't , and rather then just thinking it's the immobilizer you need to know for sure ! Is there any light's lit on the dash flashing when you try to start the vehicle ,or a light - Security , a key an lock symbol ? If not I wouldn't think it's a anti-theft system problem ! Before you start replacing parts needlessly an chopping into wiring harness , I suggest you have it taken to a ASE certified repair facility !

2001 vw passat...its starts up and then shuts off within 2 seconds...imobilizer light comes on...when car sits for a while its starts....but then it will not start intermitantly again? help!!!


You have an electronic immobilizer key recognition problem. Your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel. Do you have this warning symbol lightning on the dashboard?

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 another ignition key that you have, and start the engine.


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

Starts runs than shuts off after replacing ignition wires and bat


The light with the key through the car is the immobilizer. When you changed the battery it must of screwed it up. You will likely need to tow it to the dealer.

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.

If it is the immobilizer, there should be a symbol on your dash that flashes a key/car. If that is the case, only a VW dealer is authorized to program your key.
