[QUOTE="E. Meyer"] Assuming you mean the batteries in the keyless remote, my Hondas tend to need new batteries after about three years. The Nissans seem to last about twice that long.[/QUOTE] I also seem to get pretty good distance out of it. Not sure about the Nissans, but greater workable distance=less battery life. Besides, those lithium cells are only 2 or 3 bucks.
