repairing window lock

[P MONTY]

HI YA,

Moved into a flat and noticed that one of the windows wasn't correctly locking.
I tried searching online but struggled to find out how to replace.

The one in the picture is how it should look but the window that is broken has the grove missing. Is this something what can be replaces easy?

the grove missing

what is a grove?

is there a maker's name on key, handle or mechanism?

It's a Roto lock

Not sure what though - is it tilt and turn

Your right it’s a Roto, I photographed the actual one what doesn’t lock. It shuts but it can just really be pushed open. I’m not sure in the technical term but I think the grove had fallen out the top.

it’s not a tilt and turn, found out our apartments were the first to be built as a show apartment and the other blocks all have tilt and turn windows except us.

I can’t see how to easily replace or where to find the same espage. If that could be replaced. There’s no screws holding it in like a door it looks like it’s being held in by a small Allen key screw. There is no part number I can see so I’m a bit lost.

Many thanks
