Anyone tell me how/ where I can get some spare keys cut for my '85 Kombi?

Found my last key type on fleabay and then just had a locksmith cut it from the original.

I'm not sure what key type yours will be but a bit of a look around the web should turn that up pretty quick. They started SC then SG and so on.

Try a VW dealer for a blank, then take it to a locksmith. Your original should have a letter on it like "N" or "K". That is what the blank is.
