I have changed the battery on my Sigma Fob AC110 immobiliser but it is still not working, am not able to use the key only as it seems as though the immobiliser has by passed the factory fitted system, I cannot find any codes to use for the fob, does anyone have any ideas on what I can do, as I am currently using the spare fob but am worried that this will not last long and will then not be able to use the car at ..

 

Where are you based ?
