Hey guys, do any of you know where i can get replacement keys for the OEM installed roof bars. I am looking for the small plastic key used to remove the plastic covers that sit over the clamp section of the roof bar. I phoned my local dealer and he was happy to sell me four new covers with two replacement keys for $140. Seems a little excessive for 2 tiny bits of plastic. Does anyone know if the Thule barrel locks (or Rhino etc) fit the hole.
