It must be possible. Interestingly has anyone had there 155 stolen? If so they must have overcome the immobiliser somehow. Any ex car thieves wanna own up to how it is done?

It should be of course "Any of you bright..."
I always get excited coming on this forum.
So, if I were to replace the ecu chip with a non-alfa-code chip would it start?
How is the igniton key linked to the ecu?

Is there a reason for doing this? You will have a car that is easier to nick and higher insurance premiums to go with it......unless you're planning to replace it with an aftermarket system.

The ignition barrel has some sort of receiver in it to recognise the key...JB will know more, where is he? :confused:

My local dealer told me that a specialist in Cardiff can cut keys and copy the code from your original key and put it on to the new key.
I was thinking about this myself as I have no Master key and to get 1 the dealer told me that I need to replace
1. The Complete Lockset
2. The Code Box above the fusebox
3. The ECU but on mine I can get the ECU wiped

Check with your dealer to see if you can get the ECU wiped if you need to get a Master key

I knwo a reallt cheap way to get other keys working in the car.

Open up the keyfob and take out the immobiliser deactivation chip. (should be in a wee rubber insert bit)
Open up the steering column cowel and silicon it onto the cover or chassis right beside the ignition barrel and put iot back together.
Now all you need is a copy of the key as the immobiliser bit is in the car.

Maybe not the bast way as thios will effectively knock out the immobiliser function.
But it will work 'till you decide what you want to do with the immob and the alarm will stilll work ok.

If you can't fix it cheaply... bodge it D:

My 16V 'lost' its code system last two weeks ago, after buying every part of the system, ariel, CCM box (the bit that sends and recives the codes), trying all the fixes-holding the batery leads together, new batteries, etc, we finally had to admit defeat

The ECU was sent somewhere and had its alfa code system wiped. The car is now fine. It has a laserline imobiliser anyway. Just had to remove the code bulb from the instrument dash

If you want to know were to send your ECU ask Howard at Allitalia on 01978 757588
A new ECU is 650 quid i beleave !

The Code is held in the ECU master unit, not in the Injection Chip, you carnt do anything to the ECU yourself, if the code light is on and it wont start... then from my expirience your knackard...

But other people on this forum have managed to bring there cars back to life, do a serach for Alfa Code

This is great stuff. My last 155 came without the master key, and FIAT were completely snotty about the whole thing. Almost put me off Alfas for life (for about 2 seconds :D )

Anyway, good lateral thinking, lads.

fkcream - I take it your car did not start after the code failure?
If squadra or anyone else supplied a chip, would they need the existing chip to transfer info?
Anyone here have a squadra chipped alfa-coded 2.5?

I have a sqaudra chip, but that is nothing to do with the imobiliser... we changed the squadra for the orginal chip, it made no difference..
If you have a problem with the Alfa code system try a new car battery first.. after that a new Key ariel and a new Key register box.. after that just wipe the code, call Howard, he can tell you were to go to sort the problem

my car was driven off the ramp after an engine rebuild, it was switched off after idling for 20 mins... the the Alfa code problems started.. two weeks later the ECU had to be wiped of the code, now its fine

We tried everything... it just would not recognise the keys...

Who's this guy Howard ?
I have just returned from Holiday after 3 weeks (forgot to disarm alarm/imob) and had a flat battery.
recharged battery but now the code light is flashing, I have used the master key but still nothing.
I have looked through manuel and it says the code is a 5 digit no. but on my master key I have just two 4 digit no's.
Your thoughts please !!

Have you tried a new battery? Someone on here tried to charge a battery but the code wouldn't work until he replaced it...... :confused:

I get this prob every time i disconnect the battery, im not sure wot the answer is but this usually works for me:
disconnect battery and charge fully
clean terminals with sand paper and the connectors
tap all the relays around the battery
reconnect battery making sure all terminals are tight with good connections
insert key and attempt to start, should not matter which key you use but you may wish to try with the master first
