unless you have had blocked duckbills you are probably looking in the wrong place.
I would be looking at the pick up ring around the ignition barrel. Especially as its sometimes worked
Shame you haven't a spare key as this would eliminate one possible cause.
I haven't seen the pick up coil fail on a Panda. But it is fairly common on the Punto. No doubt they are the same.
I would flick the pick up coil out and get it closer to the transponder chip in the key. Then if it then starts drive it home. Once started the immobiliser will not kick in again until its switched off.
