Try operating the lock electronically and mechanically several times and see if the door then opens from either inside or outside.If it does then the door panel needs removed and linkage inspected leading from the lock rod and handles to see if it needs adjusted or if it is hanging up at all.If this does not work to open the door let me know so we can continue.
If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.
Can you reach into the latch area with your hand,coat hanger or similar to try and pull up on the lock rod to see if it moves any further then see if the door opens?
This sounds like the latch itself has failed inside the door.This is unfortunate as I have seen before a few times and usually requires removal of the door paneling with the door closed like this which usually ends up in damaging the door panel itself to where it needs repaired or replaced after the latch is removed.In some cases this involves a lock smith to cut off the door latch striker to then open the door to remove the latch so it can be replaced.This does sound like what is at fault here for this issue.
Unfortunately these are the only options I have on this here myself.If you want I can open your question up for others here to see if anyone else can assist further on this just let me know if this is something you would like to do.
