Alfa 159 - re-use key fob ?

[szkeptmen]

Hi,
Customer has only one working key to his Alfa 159 (year 2006)
Inside PCF7941

He has a second key from a scrapyard...
Can I re-use with replace the PCF and with EFFI ?

No one took the key programming.
They certainly know something that I do not ...

Unfortunately you can not.You have 2 options.
Order key from dealer.
Or unlock that PCF7941 that is originally on board.
Prepare key by Effi,and finish programming via OBD,else remote won't work if written directly to dump.

Key from dealer... about 300 euro :(

OK, but why need unlock the used PCF7941 ? How can I unlock it ?
Replace PCF to a brand new one, program with Effi (menu 173.) ???
Only transponder will works ???

[simaservis1108]

Yes that is right.PCF7941 is programmed with specific eeprom data that regular transponder machines can't program
That is why you need unlocked PCF7941,it will have the right eeprom data.
Blank PCF7941 won't have that data,so it will only start the car.
You can try companies that do the unlocking of car keys.

Forget to unlock that pcf because key is from scrapyard and you dont have original BCM to take info for unlock....

[simaservis1108]

You have a PM who can unlock it.

[didi_du_93000]

I know orange5 can unlock pcf7941

But don't know if it's working with all brands cars or just with some.

[koyot]

no all brands

[szkeptmen]

You have a PM who can unlock it.

PM me too, please !!!

[szkeptmen]

I knew it already... they do not have solution Fiat, Alfa, Lancia keys... : (

[didi_du_93000]

TMPRO can do it for fiat 500. So maybe it's working for alfa 159.

Ask bogi...

[simaservis1108]

Fiat 500 = PCF7946,simple swap.
Alfa Romeo 159,Brera and Fiat Croma = PCF7941,blank PCF7941 only starts the car,but no remote functions.

[koyot]

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?

[riprex]

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.

I don't stand you... what i need swap in PCF7946? VVDI can unlock some 7941 remotes... but i not tested yet..

And what tool can extract crypto code from these Body Control... (I alredy know brain.exe ... but i not having the enough time to use it and obtain results :chuncky:)

[riprex]

Could you please help me with coding that PCF? I would like to finally make it work. I have got original key with new blank PCF7941 in it, but I dont know how to add it.

[riprex]

Anyone anything?

[paul_12345]

Anyone anything?

you can not program a new pcf7941 chip

[riprex]

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.

[keysph]

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.

[simaservis1108]

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

[riprex]

keysph (http://www.digital-kaos.co.uk/forums/member.php/236256-keysph): Thank you for usefull advise!
simaservis1108 (http://www.digital-kaos.co.uk/forums/member.php/388275-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.

You can program pcf chip?

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