Audi Repair: Remote battery replacement A4, keyfob, battery replacement

Question
How do I replace the batteries on the remote of a Audi A4 1999 model?

Answer
This procedure is more easily done with pictures, I am sure someone has posted this on the forums.  try www.audizine.com, www.audiworld.com or www.audifans.com for a detailed description of how to do this.  Once you know where to press, the keyfob comes apart fairly easily.  Jan
