Can anyone point me in the direction of a replacement mechanism?

Hi all, the locking mechanism in our downstairs toilet is dodgy at best!

The locks shoot out the side, but only one of them is working and that one doesnt seem to engage fully meaning the window can be opened with a bit of force.

Not tried to take apart and look at it as thought it may be best to just replace the mechanism but cant seem to find what im looking for?

Try S2 or S3 locking mechanisms/or shootbolt
