Teh problem is in the lock cylinder itself.  I took mine out of the van and
carefully disassembled it and cleaned id and lubed with tri-flow.  that
helped some but still was not great.  I then slightly modified a few
tumblers with a file to make them less exact about the shape of the key
that would release them.  This slightly compromises the security of the
lock but I'm not worried about it.
