I'm going to try not to go over old ground but if you feel I am I apologise in advance.
Like plenty of other Alfa 159 owner's I'm in the precarious position of only having one key and no spare.
After searching the forum I discovered like many others the keys are a dealer only part because they can only be programmed once so you need "virgin" keys.
So I phoned AO in Chelmsford and got the expected new an additional key would cost near on £400.00. I'm going to say it's not about the money although it is partly about the money!!!
My main gripe is the feeling the dealer's taking the ****** out of me charging £400 for a key that's internally slightly less sophisticated than a Sky remote control!!
Any way, I've come up with an idea and wondered if I could get some feedback from some other members.
The first thing I did was order a couple of used keys from Ebay for £12 & £20. I opened up the keys to find out what components are involved. As far as I can see the only part inside that needs to be programmed is a Phillips Transponder chip PCF7941 ( see photos ). I then searched Ebay and found a Hong Kong seller selling the said chip for £16 for 10pcs.
My idea is using a hot air rework station is to remove the present transponder chip and replace it with a "virgin" chip in the hope this is now technically a new key.
I have three questions I need comments on:
1. Do you think this is a plauusable?
2. The dealer added £30 onto the key price if I didn't have a "keycard" however, I didn't think UK cars came with a "Keycard". Also inside my document wallet I have a 5 digit "immobiliser code" written down. Do you think this is the code needed ( I've attached a link to a Youtube video which shows a code being entered )
3. Does anyone know of a garage in the Essex / Hertfordshire area that has the equipment to access the ECU to marry the new keys up to the car?
Your thought would be appreciated.
