We live in a third-floor flat with no balcony, so in the event of accidentally leaving the keys inside the flat or losing them while out, it is physically impossible to get into our flat.
My wife and I both have our own set of keys but I'm just thinking in the unlikely event that we both lose them/leave both sets inside (it's a type of lock where it locks mechanically behind you when you close the door, without having to lock it with a key), or if one of us is at home alone for a while and the other person is away, but the person at home locks themselves out by accident.
Underneath the door mat is out of the question - too easy and also we don't know all of the families in our building. We have recently moved to an area that previously was not home to either of us, so we have no relatives nearby to simply keep a spare key. We have friends whom we could ask, but are there any other ideas? Some nook or cranny somewhere around town even?
