Courier Van lock jammed

Administrator drukte met precisie uit :

Try some car thiefs

Try some spray lube. Let it sit for a bit and try the key again. If still
no luck try accessing the lock mechanism from inside. If still no luck, try
a good locksmith...Also, I am assuming that you ensured you have the
correct key....DaveD

Like most problems I post I ended up solving it myself, so for all those
that follow:

I broke the plastic lock off by going in under the door from behind outside.
This seemed to me the cheapest part to break.  My big problem was the cage
that stopped me getting to the door from the inside, but in hindsight I may
have been able to poke a hook through and pull it from the cab.
