wow that sensors is in the door latch.......
you'll need to take the inside door skin off, then if the bolts are on the inside remove them, and the linkage rodd to the door handles.
if the bolts are on the out side life will be easier for sure as far as re aligning it so the door shuts and locks right. most of the time if you put the new part right were the old one was, (use a marker to out line the old one,) then remove it. everything should line up the first time.
