I give up - - what are deadman’s keys???

[gaijin]

Let’s say I might get killed:

I write down a long story for you and I put it into a lock box that has 20 tumblers on the front. I lock the box I give it to you.

if I am abducted and fail to check in every twelve hours to a friend or a computer then the 20 unlock numbers are released and with those you are able to unlock lock the box and read my final message to you.

I don’t have to write down my whole story all over.
