I just wanted to add closure to this thread in case anyone stumbles upon it in the future with this same problem. I was successful in attaching a jumper cable to the positive terminal on the starter motor. I then attached the other ends to a new battery and was able to unlock the doors. This is a very tricky job to do with a basic floor jack and jack stands but not impossible. Thanks again for the help everyone. Now on to tracking down part numbers to fix my door handle!
