Recently, I became a proud owner of AR 156 JTD.
I love the car but can't solve weird problem with remote central locking. Have both keys (only one has remote controls, battery is changed and new) and CODE card. Central locking works with the key in the door.
Went to my alfa service and tried to recode it with diagnostic tool, first weird thing was that diagnostic tool didn't offer possibility to recode remote locking, we only could memorise the keys. That really surprised technical guy who work there.
Then we found out that younger 156's have SPECIAL code for remote locking?!? Ok, they got it for some compensation (don't know where) and then was able to recode remote lock. I tried there, it worked perfectly, then again when I was arrived home, everything was fine.
After 20 minutes, when I was leaving house again, remote was dead as before. I tried on several locations, many times, no reaction. Went back to service after few days, they did it all again, we tried to remove battery from key fob and put it again, it works perfect. After 15-20 locking/unlocking, there and outside and later at my home, everything was fine. And then all stopped, like last time.
How this could happen, how can car computer lose that data for pairing with key remote signal? Or is it something else?
Does anyone has a clue, it is very mysterious for me?
Thanks for any help that you give.
