I have a 156 with a black flip key. Phase 2 i think.

I recently had a key repaired by Chris C - top bloke. Its a spare which works, transmits and starts the car. However the remote signal (to open the doors and boot) needs programming to the ECU (or so chris has said).

I've tried the 'press the button and put battery in' method to re-attach the key, but Chris reckons its been done too many times and needs reprogramming.

I have fiatecuscan (registered version), but there is not option there to recode a key. So i take it to an local independent specialist who has told me they need a code to program. I had the 'key card' which had a 5 digit code on it but he said they need another code as that is for programming the immobilizer?!

Does anyone know who can supply the code (i guess a dealer) or where it might be located?

I asssumed as I had the card there was only one code? :read:

Yes the code for the remote is different to the Immobiliser code on the code card.
For the 156. Any Alfa or fiat dealer should be able to order the code for you. Just make very clear when ordering its the remote code you want not the immobiliser code.
Not sure on mes but AlfaOBD will program the remote fine and can be used with the same cables as Mes.

Before you go ahead reprogramming the remote. Try disconnecting the remote receiver for a few minutes first. If you have a saloon its in the top of the boot uncilp the lining and you will see it in the centre. If you have a SW then its behind the carpet next to the fuel filler.

Thanks for the reply. Extremely helpful - why?

Might this 'reset' it?

The remote and receiver work on a rolling code. Each time you press the remote the code it transmits is different. The code to be sent is calculated by an algorithm which is also used by the receiver so it knows what to expect. But it will accept the next several codes in the sequence to account for accidental presses of the remote whilst away from the car.
By removing the power from the receiver the aim is to get it to forget where it was in the sequence. Which should make it temporarily broaden the range of codes it will accept.

Just been in the dealer to get the programming code and they swear blindly that the card I have (attached) contains the 5 digit programming code. They cannot supply any other info.

The 'specialist' are saying they need another code (and that that code is for the immobilizer) and the 5 digit code doesn't work.

Dealer ony want 55 pounds to do the job, tempted to just give it to them and let them do it...

Very confused.

156 100% has a different code for the remote that was never printed on the code cards. 147 and GT use the same code for both but the 156 has two separate units that deal with the immobiliser and remote. Strangely a lot of the dealers don't seem
to know this. Hence I said to make clear that its the remote code you want.
If you were closer i'd do it for you. Try the dealer again ask them to check if still no joy I can get the code for you at cost to me (£8.40). But it shouldn't be a problem for the dealer to get it. I used to have a friendly dealer that got the codes for me for free.

Dealer wanted £40 from me

ok thanks. I might well PM you and take you up on that offer bearing in mind what Hazz said!

The trouble is if the dealer swear blindly that the only code required is the one I have, I can't really stand there and dispute it! Saying some guy an internet forum says you're wrong isn't really going to work!

Anyone got anything (link to a web page etc) i can print off and bring to them to help my case?

Yep.
Often called the "Alarm PIN code" I think.

I called the dealer again. Had a 10 minute conversation with them. They point blank refuse to acknowledge there is any additional pins or codes they have access to. This is a main Alfa dealer so I'm assuming they should know. I quoted David C "Alarm Pin Code" and that didn't help.

I have suggested they code the key for me *if* they can assure me that they will either do it and charge me the amount quoted, or if they cannot do it, not charge me. Simples.

They've gone off to check with the service manager...

dealer just called me and supplied me with a 6 digit code starting in 0... apparently one of their members of staff knew about it. They didn't ask for a payment.

Success.

Now to get it coded!

Glad you got it out of them in the end :thumbup:
The 0 at the beginning of the code can be ignored
It's the last 5 digits that are the code.

I have my code, but refuse to pay a dealer to code it for me, so will hang loose and be happy with one key, two were working last week, so who knows, may just start again.

you do know that anyone with examiner or equivalent can code for you. It hasn't got to be a dealer...

either way it will cost you, but maybe not dealer prices?

Reusing the topic! My question is. It's possible to code the new red key fob (photo) to work with a 156?

My car has a two button fob, not three buttons
Thanks

Bumping this one up. I have a 156 SW 2002 with 2 keys of which the remote lock doesn't work. Wanted to program the keys with AlfaOBD, but I can't connect with the Central Lock unit. I'm using a FTDI USB interface with switchable pins to connect to the OBD connector.

Connecting to the ECU and Airbag unit works fine. But can't connect to the Central Lock receiver (VAS97). It should be on pin 11 if i'm right, and my OBD interface has a pin setting of '12/13', but read more often that it also connects on pin 11 on that setting. To be sure I opened up the connector, and strangely enough, I only see pin 11 and 12 shorted for that setting. Nevertheless, I would expect it to work on pin 11 tho ...

I've located the doorlock receiver in the boot (behind the boot right side panel near the fuel cap) and disconnected it. The connector that attaches to the receiver has a red wire (on pin 3 if I recall correctly) and i do get 12V on that wire, so the receiver should get power i presume.

Is there a way of testing the receiver? Is it possible to hook the OBD connector directly to the receiver, and connect to it? Is the OBD connector of the car connected directly to the receiver, or is there something else in between that can cause the problem?

Hope to get some advice.
