Then I realised; which code is for which lock?
It is actually an interesting combination of Schrödinger's cat & Sod's law - whilst in the drawer of no return both codes are in an inderminate state, being neither right nor wrong. It is only by the act of observation, being the loss of 1 key and taking 1 code to get a new key, that the code is resolved into a single state - which Sod's law dictates will be wrong.
