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.

PM me too, please !!!

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.
