VW roof rack system question
 

I used to own a 2000 VW TDI and had purchased this roof rack base system and the ski attachments. I have since sold my VW but have the rack system. Unfortunately I am missing the keys to the ski attachments. I don't want to go to a VW dealer and spend $$ to have new key lock set placed. Is there a market for these for parts or a cheaper way to have new locks placed so I could then turn around and sell them?
I have pictures but I am having trouble posting them
