Patio Door Security Lock

Niknaklady

I'll start by apologising if I'm in the wrong place but this is the first time I've ever used a forum!
My 92 year old mother was recently broken into via patio door. I have seen a 'central rail key operated lock' but have no idea where to find one. Can anyone give me suggestions where I could get one from.
The door's a double leaf but only 1 door handle.
Thank you for your assistance.

Welcome to MSE :wave: Your post is fine and in an appropriate place

I'm not an expert but, from what I can see, this central locking system is supplied with the door. I don't know if it can be retro-fitted. Is it a wooden or PVCu door/frame?

Hi

I have fitted one of these a few years back and it is still working fine. Fairly easy to fit... link
