sat over winter, got in w manual entry, popped hood, replaced battery, can enter with fob now but car starts then dies as if running out of fuel. Porsche wants me to tow to shop, not liking that idea. I've been told it may be anti-theft and keys and car will need to be "reprogrammed" How did this happen and can i next time remove ground cable to allow battery to not have any draw or will i have to "reprogram" again if that is actually what is wrong. thank you

stored my car over the winter, now I can't get the battery to even have enough juice to release the front hood, so that I can fully charge the car battery.
I tried utilizing the fuse box, red (positive connector) and the car hinge for a ground. No Luck, what am i missing?
