Another small DIY for those interested in changing there old key case/fob for the 159. I bought my car used, but the previous owner only used one key. So when I saw the differences between the used and mint key I had to change it.
First I went to my local dealer to see what he can do, but said the only available option is to order a complete new key/remote, and program it on the car... gave a high price quota for the key and programing, delivery time was almost 3 weeks.
I did some searching and found a guy on ebay (italy) who sells brand new original Alfa Romeo 159 key cases, ordered one, got to me in about a week.
All I did was insert the electronics from my existing key in the new case and swap out the metal blade (a bit tricky).
1 small phillips screwdriver
1 small flat screwdriver
1 opening tool or larger flat screwdriver
Remove the emergency key (press the small button on the key an pull it out)
Remove the battery from the remote
Insert the small flat screwdriver at the bottom of the remote where the rubber buttons meet the plastic case and remove the rubber buttons.
Unscrew the small phillips screw.
On the front of the remote insert either an opening tool (used for phones and stuff) or a larger flat screwdriver and pry open (as you where to screw a screw) the two parts of the remote. ONLY pry open the remote on the top/front part of the remote (as in the picture below) you will be unable to open the key from the lower side as it has a clam shell system holding in place.
Once open, the remote will open in 2 like a clam shell
Remove the electronic plate, and your done
Step 8 (removing the key blade):
This was a little tricky, as the blade is set in place by a small bolt/pin, I did not manage to remove the bolt, tried in many ways but with no luck. So I examined the tiny bold/pin from my new remote and decided to approach the matter with force
I took a pair of pliers and tore the key from the plastic holding, the pin just popped off with absolutely no damage to the key blade.
Reverse the order on your new remote
As I said, bought the remote off ebay (italy) ( http://www.ebay.co.uk/itm/1805610056...84.m1439.l2649
) cost me 55 euro (48GBP) shipping included, way less the my dealer asked for and didn't have to leave the car in the shop for programing and stuff. Took me about 20 min to swap, will take much less now that I did it once
Here the pics for the steps above and the result:
