Help! Central Locking...

[Tremonator]

Hey guys, need some help...

I left one of my inside lights on in my Ti while I was away and came home to find by battery had died. Everything was working except for my central locking and starter motor. Anyway, I boosted my battery and as soon as it got enough juice I heard central locking kick back on and everything locked.
Once the battery was charged I turned the car off, went to lock the car and once again my central locks wouldn't work. I checked all the fuses related to the locks and everything seemed fine.
I really need my central locks back since I can't open my trunk with the keys, for some reason the lock wont turn, weird.
Since I'm not really electrically inclined, I was wondering if any of you guys know what my problem could be?

Thanks in advance.
