People with knowledge of locks, advice needed.
An elderly relative is thinking about getting a key safe in case someone needs to get in to help them.
How safe are keysafes? This would be mounted on the outside wall near their front door.
I know no solution is perfect, but it would be nice to know roughly how reliable these kinds of things are.
Thanks for all the help everyone, they were very useful and didn't expect so many replies!
The Fediverse is brilliant!
