Ungaraging my 2007 for summer, dead battery under lcoked hood

[lurky]

Hi, i was preparing my 2007 boxster for the summer. I always remove the battery for the winter. And I leave hood, trunk and windows open in the garage because Ive been down this road before. SO i reinstall the battery and (foolishly) close the hood. I try to start it, no sound from the starter at all, but the dashboard lights up and, weirdly, the spoiler goes up. So its probably a weak battery problem, but now the switches in the cabin to open the hood and trunk doent work so I cant get back to battery. Is there an alternative way to get the hood open from inside the cabin?? Hoping i dont have to remove the tire, theres no room for that in the garage. Thanks
