2005 Corvette stored in garage with no battery tender hooked up, now battery is dead. How do i gain access in the car to release the hood to hook up a charger?

Usually you can energize the electrical system by making a mini set of jumper cables using a lamp cord and alligator clips. attach one end to a battery and attach the ground to the starter housing or any metal bracket, the positive lead to the main terminal on the starter. (don't mix up the lead ends...mark them so you can identify them.) Do not try to start the car with this attached. light wire won't handle the amperage.

You can jack up the car and hook up a jumper cable to the starter positive cable and another to ground. hook up the battery charger to the jumper cables. Charge for a few minutes to get enough charge to pop the locks. here is a link on how to make a charger connection for the future.
