If you're looking for a way to open and close hard to reach conservatory windows and don't want to invest in remote controls then try a threaded screw jack opener. They can be screwed in place and held with brackets, with the thread and handle reaching downwards for you to open and close to the distance that suits you.
And once installed the screw jack holds the window securely to stop anyone outside from being able to force it open - so there's no need for any extra locks. At Rocburn we offer various sizes of screw jack opener including 250mm single thread versions in chrome with a maximum distance of travel for your window of 205mm.
Contact us for more details on the SST710-250 Single Thread Screw Jack 250mm in Chrome.
