I don't think the nuts would cause the hatch to not open. You will probably have to crawl back to get the hatch open. My guess would be that the lock isn't opening all the way. If the nuts holding the lock on the right side aren't tight enough the lock can rotate. If this happens the key lock won't open the right side lock all the way. To get the hatch open crawl back and remove the carpet and push the white lock arm with your hand. That will manually open the lock and the hatch should open easily.
