Hi all, I have a black, 2 button flip key fob for my 156 sport wagon.

I have a couple of questions, I need to open the key up so I can repair or replace the microswitch, problem is I don't know how to open the key......?

I also want to buy a second hand key off ebay and swap the board and blade over as my current key is rather dog-eared.

Any pointers would be most helpfull

Do you have the enamel Alfa badge on the key? If so this needs to be prised out, it's kept in place with an adhesive foam.

Underneath is a screw which allows you to open up the key. Under the key blade is a small screw with an arrow, if you open the key and remove the battery and holder you should be able to lever it open, although do it slowly.

Watch out as the blade is sprung, and has a couple of small prices that are easily lost

Following amfalconer's advice I managed to get the key apart, the circuit board is very corroded and the door microswitch is seized up, won't press in.

I would be happy to tackle the job myself but have no idea where to source the right microswitch.

Another annoyance is that someone has opened it before and glued all the key back together which means the casing is all but ruined :mad:

So I think the best bet is a spare key off ebay and just swapping the board and blade over, will send off to this ebay bloke and get it done

Sounds like someone's done a bodge, the board should clean up, and you can replace the microswitches, not sure where to get them and apparently a bit of a bu*ger to solder, sounds like you have the right idea to get it fixed

Just had a thought though, I only got this Alfa last saturday and it came with 2 keys, one works fine, the other obviously doesn't.

I changed the battery in the faulty one and it still didn't work, thus leading to me dismantling it and seeing the problems.

I assume this key is programmed to the car? the key blade works in the doors and ignition so I guess it must be programmed?

Just a thought, would hate to have it all repaired only to discover it needs programming :eek:

Its the car thats programmed, not the key. If the key starts the car then its most likley the dodgy circuit board that causing the problems. If it won't start the car then someone has just had a new blade cut (the cut of the blade is independant of any programming) and stuck it into an existing key for another car. The only practical way around that is to get a new key from a dealer or good indie.

When I tried it yesterday it wouldn't start the car, but I think this is because the car was locked with the button from the other key, which meant when I unlocked it with the blade from the faulty key the alarm went off and it wouldn't start, the engine turned over but the alarm was still wailing so I guess that is the issue.

I think I will get it fixed anyway, hopefully I will be lucky and it will work!

Did the keycode light go out? The alarm going off shouldn't stop the car starting, thats all down to the imobiliser chip in the key.

If you just used the blade from the faulty key, it wouldn't start - the immobiliser chip is in the body of the key - a small "bead".......don't lose that!

Following further information I done a couple of tests....I unlocked the car via the remote button on the working key, left the working key in the house and got in the car with the old remote imobilizer chip and key blade. I held the chip against the steering wheel cowling and tried firing her up with the keyblade......no dice. The 'code' light stayed on and it wouldn't start. So it seems someone just put the blade in a second hand remote, which I guess explains the shoddy glue work....somewhat annoying, as it now means I need a new (secondhand key) and have to shell out to have it programmed which I think from what I have read is around the £45 mark :mad:

Very annoying, as in total this will probably cost me about £60 just for the priviledge of having a spare key....as it stands I still need to pay out for a thermostat at 30 odd quid.

The joys of Alfa ownership! :lol:

It'll cost you a heck of a lot more than that! Unless you have a skilled indie close to you then you are looking at closer to £300.

Another second hand key is useless as well i'm afraid.

There are some specialists who claim to be able to provide keys for much less. I have no experience of obtaining such a key but i do have experience of one of the workshops in question and if he's says he can do it then i tend to believe him!

The "Key copying: £60 + VAT including supply of key." will be for old Code1 keys (irrelevant for a 156/147/GT)

The "Key programming: £45 + VAT plus keys and code." will be for Code2/Code3 keys for a 156/147/GT
