Scrambler 1200 Pannier Fell Off!

Just about to go out this morning for a coast run and my wife asks me to pick some bits of shopping.
i grab my bag and put it on. i then throw my keys in it (1st time ever) and head off. i stop for fuel 10 miles down the road.
i now realise the bag has gone with the keys in it and now can't start it.
call to the wife and wait for a spare key to arrive and a not impressed wife.

wife has put a post on facebook but not sure how that all works.

this happened between west malling and Coxheath near maidstone
