Pop door card off, gently pull the plastic sheet away and then remove the 13 mm nut (for the window channel) on the edge of the door facing the rear. If I remember there's 2 10mm for the anti-smash guard then 2 10mm nuts and I took the rod out with the handle just be careful with paintwork.
took me literally 10/15 minutes and even the other half swapped one in about half an hour so a pretty easy job
Hope I've been a little bit clearer than mud haha
