I’ve never really liked locking window handles due to the need to escape in case of fire. The tiny keys get lost and even standard double glazed units are incredibly strong and can be difficult to break for some people.
The push-to-lock type that can be locked without a key are even worse as children tend to push them, locking the handles even after the keys have been lost.
As for security, I’m not sure how useful they are either. An intruder would have to break the glass anyway to open an unlocked handle.
Like most suppliers, we supply locking window handles as standard simply because customers want them for security purposes, however the following video demonstrates how insecure some types of locks can be, particularly the older types.
