Key Code issue

[Dyldo]

Mods: As this affects both my Mk4 and my Mk5 i will post in both sections for both responses.

Took my Mk5 Golf Tdi in for a scheduled service (under novate) and all was well until I got home. Incidentally the service happened at McGrath VW Liverpool and they were great. Even left me some mints and a half-bottle of washer bottle concentrate.

Anyway, I had my Mk4 and Mk5 keys on my keychain. The service included a check and reset of the cluster software because my MFD was always re-setting itself. So in the process of doing that they must have recoded my key and assumed the 2nd key was also for the Golf and coded that.

So now what I get is this:-
My Mk5 key works fine on my Mk5
My Mk4 key now unlocks and locks both the Mk4 and the Mk5
My wife's Mk5 key now doesn't unlock any doors at all but obviously still starts the car and locks from manual in the barrel.

Does this seem right to folks? And is it a simple fix?

Well, the simple fix is to teach your second non-working remote using good one. I don't have this with me, but if you google you can find one. The procedure includes using one key in the ignition lock and another one in the door, I don't remember, but I've done it once and it worked though it took me two or three attempts.. The same procedure used if you changed battery in your remote, good luck
