Need help unlocking/open trunk/rear door

[TOAST]

I have looked thru the forum and went on the search to see if anyone has had this happen but couldn't find anything. I have a 07 H2 and this morning I went to open the trunk/rear door and it wouldn't unlock when I used the key fob and so I tried using the unlock button inside the truck and it still wouldn't unlock. Since there isn't a key cylinder on the rear door to unlock it with a key how do I get the rear door open? Any help would be appreciated. Thanks in advance.
