Re: no brown key.... How much of a fool have I been?
You need the master key (the brown one) to add any additional new keys to the car.
HOWEVER, it is possible to clone an existing working key, so then have two totally identical keys and the car can't tell the difference between them, so the new cloned key will work, as will the original key.
This applies to the "Code1" system, which is what the GTV has.
I am open to correction on this, but I don't think the GTV ever got the later "Code2" system. The Code2 doesn't have master keys at all, just identical normal keys.
