immobiliser problems on 156

Well, thats typical Alfa .... they say.

6 monts ago I experienced the first problems with my keycode / immobiliser
on my 1998 156-1.8. It didn't function anymore, but the amber coloured
'code' LED on display didn't lit up either. Starting with the emergency
procedure however did help me. After a few days, it dissapeared and never
came back ... untill this morning! Again the same problems. Now, after some
local rides and a driving for more than an hour this afternoon, suddenly the
amber 'code key' LED lits up, saying that the module is in error. 30 minutes
later I arrived at my final destination. After switching of the engine, I
tried to start the engine again. Surprise - surprise, no keycode problems
anymore.

Weird!!! No logic thoughts on what might be wrong other than a very random
error. Anybody any idea how to inspect (visual) the immobiliser and
antenna??? I understand that the antenna must be near the keyinsert en
immobiliser near the fuse section in the cabine. I tried to see / dismount
them a few months ago, but with no result. What are the tips & tricks on
this ???
