no, on fiat code system2 the code box can be taught any key code, the ecu only recognises one code box, and the codebox only uses one code to begin the learning procedure (the code held on alfa's database), but any key can be programmed into the codebox, trust me i've done this recently on my 156 using a key i bought off ebay.
I have been very interested in this. You may remember that a similar thread came up some time ago where you said that the FIAT system could be programmed in this way - to accept any code2 transponder chip from any key, such as a second-hand one. You thought that the same should apply to Alfas. Although this seems very logical, on questioning you admitted that you hadn't yet actually tried it on an Alfa, although you thought it would work just the same as on a FIAT.
Are you now saying that you have successfully used the transponder chip from a second-hand code 2 Alfa key and had your Alfa 156 coded to accept it?
Forgive me for being pedantic aboiut thgsi and asking you to repeat what you have said, but as you know I repair broken Alfa keys via eBay and I try to deliver this as a service with good and accurate advice for fellow Alfa owners. I want to be able to offer honest advice and to date have never had any proof that the ECU can be coded to accept a second-hand transponder i.e. one not ordered new, directly from Alfa. If you have actually done this then it makes a big difference and I can change my advice and my listing.
Obviously I still like to make money repairing broken keys, but I do not want to do this under any false pretence, so if someone asks me if a second-hand eBay key can be made to work with their car then I need to give them the correct advice.
From my perspective, there are enough people who just have broken keys that I can fix and save them the recoding expense, so there is still plenty of work for me
It is a matter of honesty and service that I give the right advice.
Thanks in advance for any reply
