For proud owners of Nissan's newest Altima or Infiniti's G35 sedan, we certainly hope you don't habitually stuff your shiny new I-Key in the same pocket as that diminutive handset, or you may return from your next stop to find yourself totally immobile. In a rather bizarre (and strangely ambiguous) announcement, Nissan North America has claimed that owners of the 2007 Altima and G35 should make certain that their "intelligent key" is kept at least "one inch away" from their cellphone at all times, as getting too close for comfort could cause the keys to be "erased, rendering them unable to unlock or start the car." Interestingly, a Nissan spokesperson stated that the company found "incoming and outgoing calls had the potential to alter the electronic code within the I-Key," and as if that weren't tragic enough, the keys seemingly can't be reprogrammed afterwards. Of course, the firm assured everyone that the issue was only in "a very small percentage" of the total keys (and cars) sold, and while a new iteration will be out this fall, you can presumably rent a car and drive to your dealer for a replacement if the glitch hits your whip.
