I have replaced quite a few of these qitw no worries, however, 1 of them has no visible retaining screw. They are french doors, and this door is the one that normally stays closed (right hand side), as we only use the left hand door. It has a Yale stamp on the retaining strip down the side of the door. I will try to attach a photo. Thanks for any help.
Unable to remove euro cylinder - no screw

Remove the 5 or 6 screws running up and down the edge, it's called a flying/floating mullion and enables the master door to close onto something, the screw to remove is behind there
Thanks very much, i took the screws out, the top was loose but middle and bottom wouldn't budge, didn't want to force it! I could see what looked like metal brackets at the side but as I said, didn't want to force and break it. I assume this door is safe as I did manage to change the other lock to a more secure type.
The aluminium brackets just help locate the mullion, should come off with a twist and a tug

Hard to say, could also have blobs of silicone holding it on too
You may need to use a large HSS drill bit to drill through the door frame once you remove the mullion to actually get access to the screw.
Check out this video (and from 3.45 for the point I'm making above).

That's incorrect kingandy, if the mullion has been removed there is no need to drill anything to get access to the screw, with the mullion removed it exposes the lock mech and the screw is visible just like on the master door. However it's a good video to show how to drill a hole in the mullion to remove the screw if you don't want to remove the mullion, it looks like the op doesn't have a one piece locking strip so will just have to remove the centre striker/latch plate

I've done both, depends what mood I'm in or if I have time to waste, if its a lovely middle aged attractive divorced lady I'll have the glass out, doors off, drainage hole cleaned out, mechanism oiled, dust cleaned out from under the handles and then all rebuilt again
Perhaps I misunderstand what a mullion is, but if it's the metal bit that's in the OP's post, removing that alone may not give access to the screw.
Certainly on my french door, as with the one in the video - the trailing door's cylinder screw was behind the upvc frame. Therefore the OP *may* have to drill.
For me drilling the upvc was much quicker than dismantling any more of the door.
