Easiest way is to take the back seat base out and remove, or partially remove the door trim to get access to the lock. I think you might call the door trim "door card"
With a hatch you may even be able to remove the door trim enough to get your hand in t o access the lock without removing the seat base????
Seen the door opened in this scenario by using wire down beside the glass to reach the lock, but you really have to be a practiced "door opener" or lucky.
