Dead battery & locked out

1999 Audi A4 Quattro
Engine is a V6, with a 5-speed Manual
Mileage is about 99,000
 
No CEL’s currently (Check Engine Lights), the stored codes refer to engine computer diagnostics.
 
The battery died while stored this winter.   Now I can not get into the car.   Thought there was a hood release in the trunk, but can not even get into that with the key.
 
Any ideas out there???     I'm getting a bit desperate, but hate the thought having a service call since I am in a somewhat remote site.
 
Thanks in advance for any assistance.

I locked myself out while the car was running once, and my spare keys were in the car... So I broke the back window out... :\.... That's one option... It only cost like 50 bucks of ebay for a new back window...

well no matter how dead the battery is you should be able to put the key in the door and open it. if not, you're in big trouble lol. 

^^what he said, dude i really hope you didnt think of that because you were freaking out.

Yeah you have keyless entry but you should just put the key in the door and unlock it
 
And texas pete. Why did you have your spares in the car?
 
I mean i had the valet key on my key chain for a while but my spares were at my house.
