Bill, how smart do I have to be to operate one of these things? After I read your response I went back out, climbed in the truck, pushed the drivers door handle forward, scooted across the seat, got out on the P side, walked around, and the door was locked! How easy is that?. I had been trying to do the push forward on the handle to lock it --with the door open. Don't work that way does it? Works just fine your way. Oh my -- the older I get --- Your post just set me to thinkin' --- so thanks, Dale
