Anyone had this? I've just got the one key, so I thought perhaps the PCB is fooked. Bought a used key on ebay and decided to try that tonight. Swapped in the new batteries from my existing key and tried changing the stored value to 1 in the central locking adaptation menu. Click to save, press the key, nothing. What are the chances of me having two knackered keys here? Am I doing anything wrong? I followed a Youtube video which did exactly as I described so can't see that I have. I have managed to find the old casing of my original key and so been able to check the part numbers. They are both the same, the one starting 4D0. Very confused..... and certainly very frustrated. Does it matter that the stickers with the part numbers on are orange? I.e. not sure if the genuine items have a particular type of sticker on them etc. Any ideas very welcome folks. I ordered a third key when I was playing about on eBay so will have a 3rd option to try shortly.
