Immobilizer replacement on Alfa 147
So first of all i'll ask you to bear with me as i'm french and i don't know the technical words in mechanic. I'm actually asking on this thread because I couldn't find anything helpful on the French threads...
Anyway I'm planning on buying an Alfa 147 1.9 JTD 115 of 2002 but there are some minor problems with it, one of them being that it only has 1 key and no code card.
So I went to my local Alfa dealer and.... 450$ for the card, one key and the immobilizer reprogramming.
So as I need some spare parts I'm thinking of buying an out of order 147 which apparently has a working immobilizer receiver and two keys.
I read on several threads people suggesting the receiver replacement as a way to get two keys so here are my questions :
- Is this replacement really possible or is that just a myth?
- What should I check when I go to see the old car (I can't actually try the keys and receiver, the engine was removed), should I just open the keys to check the transponder or is there something else I could check (with the receiver itself for example)?
- The old car is from the same year, same model but only has 3 doors (mine has 5) and doesn't have the same finition (mine is a distinctive, the old one I don't know but it doesn't seem to be the same), will it be a problem with the immobilizer or the central lock (are the two even linked?)?
- If I got it correctly I'll need to get the code card from my soon-to-be car before I do the replacement, is that right? And I don't need the code from the old car?
- Finally, would any of you have a picture of the exact parts I need to check and then remove from the old car?
