These folks make a neat unit with separate mounting plates. The lock needs no battery and if you really want to make life tough on the rip off artists take out the front seat and bolt it to the floor the put the seat back. Makes it real hard to get at but you should still have enough clearance to get to it when open or take it out completely.
