Key

When I finished judging a competition at a camera club last night, I picked up my coat and drove home.  Just as I was arriving home, I received a phone call to say I had picked up the wrong coat.  One of the club members had an identical coat to mine - same make, style and colour. I have made arrangements to swap the coats back tomorrow morning (and thus regain my house keys - good that my wife was at home last night to let me in!).
