If your area has the little transponders(?) that solves the problem. But, if not, it isn't that hard to do it via the slider. Although I must say i am not coordinated enough to do it left handed- I reach through with the right hand. If I had to do it over , I would have gotten slides on both windows, so I would't have to continually open the door for passengers (95) I have had my windows about 3-4 yrs--no problems, and Biff is great to deal with. tmb
