Car Batteries
Alfa Romeo

How do you fix an immobiliser-equipped 1999 Alfa Romeo 156 1.8 TS that refuses to start - does the red car key require a battery?

This seems a common fault and can be fixed by unplugging and re-plugging in or replacing the small black cable that runs from the outside ring of the ignition switch to a small fuse box behind the shroud in front of the drivers knee. You are best to remove the steering column cover and the shroud from in front of the drivers knee then trace the wire back. The problem seems to be with the connecter at the opposite end of the cable to the ignition switch. There are more forum answers on the net that elaborate further. This is easy to fix once you identify and trace the wire!

"Another View". You dont say if when you turn key to 1st position and dashboard illuminates Does the amber picture of key go off after a second or so? If not the car will not start because the code system is not recogniseing the key. You can try turning the key back & forth slowly a few times to see if it goes out. If not you will need it reprograming.
