I have raked through the post but, can't find it mentioned... does anyone know if the key is like a radio frequency tag. the kind you get in all sorts of goods nowadays?
I would hate to think it is battery powered and have the battery go flat when travelling.
I used to work with radio frequency tags years ago and thought they were a great invention.
