Hello, N having only very little space to dismantle my roller shutter (2cm 1/2) between the wall or is built mvolet, I did not find a right angle screwdriver. TIP take a flat ratchet wrench 8 m / m and insert a plastic dowel into the key, straightening the outer part. press a bit for the corresponding screw into the dowel. It is thus possible to obtain a cross-piece for cruciform screw. It remains only to clear the remaining plastic crown on the key.
