Changing the euro cylinder lock on uPVC double door

[GusGF]

Please take a look at the attached images.

I can get to the cylinder screw and push out the cylinder on the left hand side of the double door but on the side that provides the jam to the other door (not sure what you call it) I can't see the multipoint mechanism or plate as it's buried beneath the jam or length of PVC. There are about 4/5 very long screws which I took out but that didn't seem to help though I didn't want to force it. Do I have to remove ALL the metal fittings to get this off to get access to the multipoint lock?

Thanks for any help.

No, after removing the 5 or 6 screws this should release the section of pvc called the 'flying mullion', it'll probably be held square on aluminium clips or brackets but for all intents and purposes once the screws are out it should come away with a bit of effort, don't worry there's nothing delicate behind there you could break, it'll then reveal exactly what you can see on the other door, once you have it off be careful putting the million end down on the floor, lay it flat because you'll bust off the flimsy little end cap if you stand it up against your wall

Yes that's what I was thinking. Thank you so much for your guidance

I think you only need to remove the top, bottom, and 2 screws 1/3rd from the bottom in-line. The other 2 control the latch adjustment.

Removing the striker plate won't reveal the screw though, need to remove the whole flying mullion

I was meaning leave the striker plate screws as they are, undo the other 4 and the whole thing will probably come off.

At least thats how mine was the other night!

Sorry I perhaps wasn't clear enough, removing the 4 screws and the whole assembly still won't reveal the screw

Oh? Mine certainly did....

personally I prefer not to remove the mullion (they can be a little tricky to get back on fully and get everything lined up again).
I would take off the latch plate, measure out where the cylinder screw would be and drill a 10mm hole through the mullion to give access to the screw.

It also makes access faster and easier if you ever need to do it again

Oh that's a good idea, if it will work. Hope to get around to do this in the next week or two as I've had another little Diy disaster occur

But will let you know how I get on.

I was changing locks for a landlord on a house with 3 sets of French doors.
I did the first one the mullion off way and by the time I had it all back together and working nicely it had taken 45 mins. Thats when I came up with the idea and the next 2 took 15 mins each so I always do it now
