The problem with this is that your mother had a single secret, and had somehow arranged -- what they call "out of band" -- to transmit the code to the recipient. Once in place, it could be used.
It would be useful, in her case, only once.

It would not be useful to transmit information about anything other than your planned emigration.
So: bravo to your mother; but: it doesn't scale.
Oh, and:

Um, no ... you need -- and your mother relied upon -- encryption.
