"To install these, you will need to remove the arm rest ( three screws) inner door lever ( one screw) window winder ( clip ring - need something flat to get this off) and the door panel ( 4 screws). once you can see the insde of the of the door , there is a small round hole near the edge of the frame. you will need a long phillips screwdriver to undo the screw at the end of the lock cylinder, make sure you take a picture to get the orientation correct for re-installation. otherwise you need to take the three 10mm nuts off the door latch retaining brackets ( two brackets one nut on one of them and two nuts on the other closest to the lock cylinder.and then slide the handle out of the door to get at the phillips screw) Installation is reverse of dis-assembly"
Now, I'm stuck at undoing the screw at the end of the lock cylinder. This is what I see from the hole near the edge of the frame:

No screw...I'm sure I'm missing something but...what?
Thanks for you help!
