You are not alone... and odds are there's nothing wrong with the alternator.
My Treg's battery typically goes dead within two weeks if the car's been standing still. Dealer's tried everything (or so they say), even replaced the battery - but to no avail. Seems there are so many electronics that continue to drain power when the car is parked that there is no real solution to the problem. Only piece of advice the dealer could give me was to make sure that I arm the alarm system when I park the Treg; apparently that puts many of the subsystems into "snooze mode".
After conferring with VW Canada, a last ditch solution by the dealer was to install (at no charge), a trickle charger under the hood with the instruction to "plug it in" if I plan on leaving the car parked for anything longer than a few days. Case in point - the Treg's been parked in the garage for almost four days now as I've been out of town during the holidays. Of course, as luck would have it, I forgot to plug-in the trickle charger. Soooo, combined with the cold snap we've had over the past few days, she wouldn't turn over this morning. Lights would come on, and starter would turn a few times very slowly then give up... Luckily, this has happened so many times that I bought a portable booster pack.
As I've stated in another thread, not exactly what I was expecting when I bought an over $60k vehicle. Heck, I remember leaving my old '84 Fox wagon parked under a snowbank for a few months then having it start on the first try!
EDIT: There's an electric servo that holds the key in the ignition, so yeah - without any power you won't be able to pull it out. Had never heard of the trick that PinkCadillac mentioned, so you might want to give that a try. Also, if the battery goes completely dead (as yours appears to have done), and the alarm was set when you parked it, get ready for 15 minutes of the alarm siren blaring once you get it started again! Don't know why you can't seem to boost it. Booster posts are located under the hood close to the windshield, on the driver's side. Negative terminal is near the wheel well, positive terminal is usually under a red plastic hinged cover. Good luck.
