Key Turner Handle

25/03/2022 added a version with a 5mm hole in the end of handle for cable tie or rind etc etc

This is a tool which I needed to make to help my parents access their house and it is likely to be useful to other elderly or people with limited strength/agility in their fingers, hands or forearms.

My parents use it by leaving it in a convenient place near the front door. They put the key in the lock as normal and then slide the tool over it so they can turn the key.

Obviously there are risks and they need to
