There is an interesting discussion here on the VW/Audi forum which highlights the problem concerning the use of sophisticated scanning equipment which can read your key from within your home. This is being used by thieves to open cars usually parked in driveways. There were reports of this happening to BMW owners on the ED Forum not long ago. Unsurprisingly my car now has nothing inside except the manual!
