I took a stab in the dark and entered a model and trim cuz you didnt say what she had, hopefully its the same.
The door can be opened by removing screw #44 and popping the cover off and pulling the cover towards the front of the car. If you take inside handle cover off and it completely comes off, you should see a steel wire, unlock the door and pull the wire foward, the door should open.
Since it wint open from outside or inside,
Most likely clip #17 has failed that why it wont open from the outside
And since the door wont open from the inside, clip #40 or clip #22 have failed.
Clips are 3-4$ at honda but a pain to replace.
