So are you trying to open your trunk with the manual key and cant?
I may be able to walk you through opening the trunk manually, when you insert the metal emergency key blade into the trunk lock, does it at least turn?
Are you having any trouble responding?
I'll try switching modes
If you know how to take the metal emergency key blade out of your remote (it is where the key ring would attach) take it out and insert it into the trunk lock in back by the handle. Then turn the key all the way counter clockwise, once it is all the way counter clockwise, pull the trunk handle and the trunk should pop open. From there you have access to the battery to charge or jump it. If the trunk doesn't open, let me know.
