remote battery shut off switch

I was joshing on the neatness.
My car is a streeter too, with the single battery in the right rear, and with an outside shut-off. I too use it for anti-theft. I have other anti-theft systems on the car too. When I stay at a motel,600 miles from home, I leave the doors unlocked, and go to sleep. Soundly. The car has always been there in the morning.
