Just put a push button for start, up under the dash.
Switch under the dash, and put a well marked big red dummy switch on the dash. It is enough to confuse and deter most of them.
Not really worried about it though. There are only three routes out of town, that you could make it out hauling a tractor on a trailer. Town is only about 2000 people, the whole county is only 4000. And, every body in town knows that the little TYM lives at my house. Including the Highway Patrol and Sheriffs Deputies. I plow the church next to the Courthouse/Sheriffs Office/Jail, so they have all seen it with me on it and know me well enough to say high and exchange waves. And, if the County guys haven’t made it to the Courthouse when I get done, I plow their parking area.
Part of why we have such a low crime rate is that everybody still knows each other, and it is a long drive out of here to anywhere you can blend in and not be noticed. And, people watch out for each other still. hard to be a criminal in this environment.
Not sure of when I last locked my house. Probably 4-years back when I went out of town for three weeks. The Neigbors all know me, and I know them. I had a girl freind who would come stay for a week every month. First time she left and went to the store, in my van, the neighbors called me to say there was a woman at my house, who had just drove up in my Van. I invited them over to meet her. She lives in Phoenix, and was shocked when I told her that everybody called me to let me know there was a strange woman driving my van, and going in and out of my house.
