My wife's key card has stopped working. No response at all from the 3. Mine works normally. I thought maybe the car sort of "forgot" hers for some reason, so I went into the process to add a new card, but it doesn't recognize it at the step where you put it by the cupholders. Weird. Or maybe not so weird. The card has a small stress crack in it, presumably from bending over the past 3 years. It was still working for a while after she first noticed the crack, but I guess it must have split further and broken something critical within. Sigh. Off to see about buying a new one. Have others had their keys crack or otherwise wear out?
