I purchased an '87 2WD van and went to fill 'er up.  Could not get the
locking filler cap to budge.  Looking at the pictures here: h
ttp://www.thesamba.com/vw/forum/viewtopic.php?t=540921, it seems that my
key is not seating properly.  It certainly does not go into the locking
cylinder as far as the one in the pics.

Anyone have any ideas how I can resolve this or must I call a locksmith?
If I could just get the darn thing off, then I could dismantle and clean,
but at this point I don't know how to proceed.

Thanks, Rick
