Conservatory door handles for upvc doors are usually fitted to a double door combination. One side (known as the slave door) has no external locking feature but does carry a handle. The main door has the full lock in the same way you would expect to see for front door handles. In such cases the slave door is locked independently. This is done by either a multi-point lock engaged by turning the handle or flushbolts on the inner edge of the door. When the main door is closed and locked this also then locks in the slave door. The slave door has a separate mullion attached to the side of the door. This extra frame is for rebating the door behind the main door. When changing the cylinders on a slave door you can take this extra mullion frame off the door to access the cylinder lock.
When it comes to replacement upvc conservatory door handles life starts to get a bit tricky. The problem here is that the door designs have continually changed and for reasons of security. This has led to different combinations of upvc door handles being used and many are no longer available as replacements. This video shows you some of the options for uPVC French door handles including using a half cylinder for extra security.
