There is a hole when the door is unlocked, but when you lift the door handle to engage the multipoint mechanism it slides a cover over the hole, so obviously there is no way a screw can be put in. It looks like there is some sort of internal screw or bolt used to secure the cylinder in position (it doesn't move), and the hole which gets covered is the access to this.
Any ideas how I get the screw out in order to change the cylinder??
The mechanism is stamped "For Profile 22 By Yale"
A post i found which describes the mechanism better than i can is this one;

Some of the doors we have around here have a slide that goes up and down when you left the handle that cover the screw that holds in the cylinder.If the cylinder retaining screw is loose it jams so the handle will not remove the bolts.try to move the cylinder in the door when you push down on the handle.But this is just 1 of a lot of faults it could be.
