Hey Mike,
In this particular case it will not be that elaborate. It will have one or
maybe two sliding panels that will enable it to unlock. No key.
I'm thinking of a way to engage a spring loaded button on it somewhere as
part of the mystery... but my head is so rummy from close up whittling
that
I only have a shadow od an idea.

I thought that some inset gemstones into the borders with one of them
having
a catch on the bottom with a spring that held it up..

Another common trick is to glue a rare earth magnet inside on something that
needs to move. Place a magnet on the outside and move it in the right way.
