Lets all chime in...
 
Here it is the **easiest** way with out having to put anything back
together:

Take a handsaw (ripsaw) and go through the side sliding window!

The saw is long enough and strong enough to push down the sliding window
lock and skinny enough to slide between the sliding windows.  5 seconds and
your in.

Here's the second easiest way (doesn't always work but I haven't found an
instance were it doesn't)

Because our vans are getting older and worn the tumblers in the key cylinder
are not as they were when they were new.  Ergo... use a key from another van
and giggle it a bit and presto your in!  I use the second way on my two
vans... yes the digi-wife has locked herself out a number of times.  She haw
now made keys for the kids so there is always an extra key floating around.
