Passenger door doesn't open.
 

I have a 2007 Accent and haven't been able to open the rear right side door. Can't open from inside or outside. I could fix the problem, if I could get the door open.
Any ideas on how to get the door open?

You probably aren't going to like this, but if you get no other worthwhile reply, and you have the time , open up the rear door covering on the other side and see where the door latch can be released and you might be able to release it with a homemade tool once you know where it has to go and what it has to do to release the latch.

Yeah, would examine the other side door and find a way to release the door panel.

I don't see any way of removing the door panel with the door closed, can't get at the screws or to pry panel away. Oh well, I'll just keep at it.

It may take you under an hour to remove the other door panel and see how the latch is released.
At least with that knowledge you would know exactly where to go and what to try to release so you could get the problem door open and proceed with repairs.
Maybe you might get lucky and get the latch released some other way, but depending on how much hair you have to pull out it might be less hair pulling to know what you need to do and just do it, That decision is up to you.

Yeah sometimes, can not remove the panel but can move it enough to reveal access to the release.
And as Hanky said, figure out what needs to be done first then attack the problem door

No it open try properly.
