I've had a bit of a problem when changing the locks in my mk5 fiesta, was moving the transponder from the old key to the new key and it shattered and is stuck in the old key. It does still work but I don't want to risk moving it now.
The cheapest option would be to swap the ECU out for a replacement that came with key transponders etc.
Anyway, I've been reading that the code on the ECU must match the one in the car already (EG, JEER or CLIP).
Does this matter if I was to change the transponder ring aswell (around the lock barrel) with a matching one to the new ECU, or is there more to it than that.
Ie. would this one work http://www.ebay.co.u...=STRK:MEBIDX:IT
Sorry if this is a bit confusing.
Would appreciate your help,
