Undo the torx screw that holds the outer handle to the door, but don't remove it...there is a spacer which fits into the door handle which may drop into the door cavity if you do (Most of the time, it stays located in the handle). Slide the handle slightly to the front of the car and it can then be pulled partially away from the door which will reveal a rod secured with a clip..remove the clipand disengage the rod.
Presuming you have removed the door card and partially peeled back the foam water shedder, disengage the cable from the interior door handle by lifting the cranked end of the steel cable gently upwards from the plastic retainer on the handle. Working inside the door cavity, remove the clip securing the rod from the sill locking button and disconnect the rod at the latch lever.
There should be enough room to now "Jiggle" the latch to a position where the cable from the interior handle is located can be unhooked from the operating lever on the latch.
Disconnect the wiring connector(s) to the latch.
You will have to probably fiddle about a bit working the latch out of the cavity, but when you have found the right way it will be easy.....bit like those old wire puzzles !!!
Good luck.
