This article is from the Watercooled VWs General FAQ, by Jan Vandenbrande with numerous contributions by others.

A: This has received some protest, but I decided to post it anyway to make
people aware of the ease with which one can break into a VW, and because
advertisements for the deterrent actually has a picture on how to do it.
Punch a small hole with a screwdriver directly underneath the doorhandle
(underneath the lock) and move screwdriver up and down to unlock.
ADP armor door plates are the only safeguard. (800) ADP-LOCK, about $50 per
pair. Install in 5 minutes with just a screwdriver. Other brands exist.
Stay away from flimsier products though.
An alarm with engine lockout is also HIGHLY recommended.
Newer VWs come with such an alarm! Apparently very effective.
