Hi peeps, So what is the cost of buying a complete second key with the remote from an Alfa dealer? At least that way you would get a second key which would be paired to your car. I know if I lost my key I'd be stuffed so in that case I would'nt mind spending some money on buying the right thing once.
Quite right - you need to specify the codes from the key card or
the chassis number of the vehicle which originally housed the ECU installed in your vehicle. The cost per programmed key is about £135 (possibly + VAT!).
Just looked: Seller's username was "key-blank"
Link to previous one which is an a602 blank http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=350067236986
Looks like they have none for sale at the moment but you can always email and ask. I did and they listed it.
I did what you suggested - avoid key-blank
- I bid (too much as it happened) and took the blank to an auto locksmith who started to cut it and ruined a cutting head (cost £65 to him to replace that!) because this **** had used a CNC machine to make one out of stainless steel. Another locksmith confirmed that this would ruin his expensive machine too.
... I went through a LOT of effort ( and no little expense ) getting a good second hand key fob - the tracking down a correct blade. Which are NOT the ebay ones from Bulgaria etc.
I was warned to avoid all fobs from Ebay - most were said to be useless. As far as the blade goes you were lucky - see above.
However, when I took it to a dealer ( a good one ), they couldn't get the car to recognise the key. They then tried 4 other keys that they had around and NONE would work
They reckoned that the ECU in the ar is programmed to recognise a set range of key numbers - so it's pot luck if the second hand key you get is in this range
Could well be.
There is another twist: there are chips in the key fob to control the central locking / immobiliser (not sure which) and separate from the control for the ECU. If you have a mismatch between ECU and immobiliser you won't start the car.
All told I ended up having to buy 2 keys to match the ECU and one for my original so that it matched the locks / immobiliser (I still had the old one). All told, with the cost of a second-hand ECU thrown in it cost about the same as getting a new unprogrammed ECU fitted to match my old keys!
