I bought a trunk lid at a junkyard ($10), rather than a new one online ($90) or the dealer ($130). The junkyard ones still have the existing lock cylinder in them.
I managed to sort it out.
TO REMOVE THE EXISTING LOCK CYLINDER WITHOUT HOSING THE LATCH:
1) Take lid off the glove box (so you can turn it around, and see where you are working)
2) Buy a $3 set of dental tools from the drugstore (usually includes a small mirror, and two curved tools for scraping tartar).
** These work great because they are already curved, thin enough to get in the gap of the tab and cylinder, and they are also stiff enough to not bend or break. The mini-mirror is also somewhat useful to see what you're doing.
3) Lift the latch (like you're opening it). Insert the curved dental tool into the space between the plastic tab and the lock cylinder.
4) Spread the tabs WITHOUT breaking them.
5) With at least two tabs bent back slightly, use a flathead screwdriver inserted into the lock to wiggle the lock out of a latch.
6) re-install lock cylinder onto the junkyard lid.
Took a little extra work, but got a lid for $10, rather than $100+. Granted, my junkyard was a great deal, but I saw plenty of other (non-matching) VW lids for $35-40 at other yards...
