Broken UPVC window lock

momnco

Hi.

In my loft room i have a small Upvs window that the kids have snapped the handle off.
The bardel is snapped clean off to to base of locking mechanism.

I have tried to remove lock but i can only find 1 screw underneath a metal square cap.

The other side has a sunken metal square which look like a cap but it will not budge or move to allow me to see if theres a screw under it.

Any ideas or help would be appreciated.
Thankyou

The sunken metal sq is usually coloured plastic and pops off to reveal a screw. Use a sharp point to pry it up.

Hi.

Thankyou ive tried that it wont budge. Im just scrapping the metal squares surface, (why is it sunken and not like other side)

Because the handle hides the exposed screw when closed.
