Hello Steve and a very warm welcome to the forums.
When you say the door is stuck does the key fob unlock it?
If the door unlocks then it sounds as if the small metal rod joining the handle to the door release has broken or come loose.
Can you open the door from the inside?
Have you tried pressing the remote door locking mechanism inside the car. It is the one located on the arm rest between the two front seats.
Sorry for so many questions but I am tring out all the least destroying methods to your car first.
If all else fails then I'm affraid that the interior door lining will have to be removed. Obviously with the door shut then you wont be able to get at the screws. Drastic measures will have to be taken.........
I think it will mean breaking it.
Once the inner panel is out of the way you could then try and jimmy the lock to open.
Sorry to seem a bit vague but I hope I have helped a bit.
Good luck and kind regards Oily.
