A friend had his keys literally fished, with a rod or similar from his hall table through the letterbox. Ever since, though our hall table isn't accessible from the letterbox, I've insisted that all keys are kept in an unusual and unexpected place - of course the disadvantage of that is that if they were to want the car sufficiently (unlikely for our cars) they might wake you up and "encourage" you to provide them. Quite often the OH doesn't put them in the correct place but then as she can't find them, I doubt they could either! Hope all turns out well - there have been happy stolen car endings on here recently.
