Two questions:
1) Who can unlock key from body dump?
2) Which tool generate properly id48 to start engine? I tried effi and tango without success. TMPro probably? Any other?

Hi, can you please anybody help me with Alfa 159 key? My key died (first went remote, after about 3 engine starts starting died also) so I take spare one and that works fine. In my first key I found, that PCF chip is dead completely so i replaced it for new one. I know, that remote will be dead, but I want it to be at least able start the car. When I try to program it with AlfaOBD it could not recognize new transponder. Where could be the problem? I was thinking, that blank new PCF would be fine for coding engine starting. Thank you for any suggestions.

Why not? There are some people who has done it. I know that to program new key properly by Examiner or AlfaOBD etc. I need Fiat precoded key, but that is too much expensive. But it should be possible to program it by reading car body computer and add it manually. Key should be able to start the car, but remote would be dead. I have tried many locksmiths here in Czech Republic, but nowhere near they could do this and original Alfa key is very expensive so I would like to do it myself.

yes you can get the immo working on pcf7941 but you can't get the remotes working.

Clone the chip on a tpx4 and put it in your second hand key and remove the board or the antenna.
You will be able to start the car but you will have no remote.
Better than no key at all.

I have repaired many AR 159 keys.Never replaced the PCF.

keysph: Thank you for usefull advise!
simaservis1108: This key was completely death. One day morning I could not unlock my car with remote, so I was thinking it is only battery and unlock it manually. Car started up and I was going home from holiday. On the way I have stopped at service station and after having a lovely brunch car not only refused to unlock by remote but refused to start at all saying only "electronic key not recognized". My friend bring spare key and car started well and all was working fine. But first key remained completely death. There was no reaction of transponder to car, coil was OK as was all other capacitors etc. So only thing that could be death is PCF.

There is any chance to add external/universal central locking?
