I have tried all the methods that are on Youtube and just about everywhere else - wothout any luck.
I then decided to squirt lots of WD40 in at the handle opening and left it for about 10 minutes.
I then sat in the drivers seat, turned on the ignition and using the LOCK / UNLOCK switch in the door armrest, pressed the
LOCK / UNLOCK switch a few times, and the door latch worked.
I then got out of the car and locked it - all doors locked and unlocked both with the key and with the button on the key. https://www.pistonheads.com/gassing/imgs/2.gifhttps://www.pistonheads.com/gassing/imgs/6.gif
