Changing door locks

[thebullettrain]

Sorry if this is a repost I need to replace UPVC door locks. I remember a post here a while back with a YouTube video link. If anyone knows of the post link or the actual video link then please post! I trawled through 43 pages of posts on my iPhone but cannot find it myself.

is it just the cylinder or the complete mechanism, if its just the cylinder, a single screw holds it in place on the edge of the door.

when you take the cylinder out measure from either side of the screw hole to get the length. eg 55mm 65mm. hope this helps
