Release Vibe rear window (hatch) glass?

One of the local "remove the part yourself" wrecking yards has a Vibe with the rear glass in better shape than mine, but of course the vehicle
has no battery and the normal way of unlocking the glass does not work.
Any ideas on how to release the glass without power?
