First, electrically, all the door locks operate off the same circuit, so that if one door unlocks electrically, then they all should work.
But as you stated, it doesn't sound like an electrical problem.
Second, when you insert the key, does it turn? If it turns, it looks like there might be a linkage problem. You will need to open the door panel to investigate the problem.
You might want to invest in a repair manual available from your local auto parts store. The "Haynes" manual I have has some photos and diagrams of the liftgate panel removal and the locking mechanism and instructions on removing the panel and lock.
My "Chilton" manual does NOT have any diagrams of the liftgate assembly.
