Hi, think this is my first post here. Had a new mechatronics unit fitting last week, 2019 Kodiaq 1.5 tsi, approx 50,000 miles. Lost the odd gears and finally got the local dealer to investigate and a new unit was replaced under my extended warranty.

Now the second key (i.e. the one that was at my house whilst the car was at the dealer) doesn't work at all, doesn't remote unlock, not recognised by the car. Obviously replaced the battery but no change. Tried to resync as per the instructions in the manual but doesn't work.
Does anyone know if the coding work they do to the mechatronics affects the keys? Taking it back to the dealer today but trying to get my ducks in a row so I don't get fobbed off (pun not intended)

To answer my own question is case anyone else comes looking. The person at the dealers services centre just looked confused as to why there would be an issue. The second person sitting on the desk next to him then confirmed they code the keys to the mechatronics unit. So if you go in to have it done take both keys!
