Cross bars. Please help

I have a a pair of cross bars that I got a while back for my Jetta sports wagon. But I lost the keys to them and so need to get them re-keyed. But the lock smith wants to know who makes them before he can re-key them. VW won't tell me. Anyone know????? There after market VW cross bars for a 2004 sports wagon. They already have the bars that run length way along the top of the car. These are the cross bars the cross the car width wise. Any help is appreciated. Se baught them straight from VW in germany so they are in German.
