I've just looked around a rental property and some (most) of the windows wouldn't open.
1) "pushing" the button in didn't release the lock and I suggested that this meant they were broken. The agent suggested that they were locked, but ISTR that if they are locked the button won't push in - is this right?2) If they are broken, is there an easy way of removing them without destroying the window. The lower screw is inaccessible when the handle is in the closed position.
I assume that there is a standard fitting inside the window for them to screw into. I have found replacement parts on t' net.
TIA
