The house I've moved to has window locks installed circa 1980. I have about 5 keys for 20 windows, but they have a habit of breaking. (teenage children may be involved here).
I'd like to get some spares before I run low. However they aren't a standard window key I can get from various supplies, And they aren't a template the local locksmith or Timpsons can copy.
I know I could replace all the handles but this does seem like a sledgehammer to crack a nut.
Does anyone have any ideas as to how I could get a copy done? I was hoping I could find someone to 3D print copies but there seem no services in the UK
