If you have a 2007 Nissan Altima or a 2007 Infiniti G35 Sedan, you might want to keep your mobile phone in a different pocket than your car's fancy I-Key fob. The fobs, as you're probably well aware by now, enable and disable the cars' keyless ignition systems. According to Nissan, the problem is that if the fob is touched by a cellphone while a call is in progress, the software that controls the I-Key's automagic goodness could be altered or erased, rendering it useless. Furthermore, the damage is not reversible, and the I-Key simply becomes landfill fodder.
Nissan's modifying the key to correct the issue, and will provide new ones to owners once it's straightened it all out. According to the AP, this'll happen sometime in the fall. In the meantime, some dealers
are stocking up on spares just in case, and you'd be advised to follow Nissan's advice and keep a little distance between the key and your phone. After all, you don't want the simple act of pressing the Start button to turn into an exercise in futility -- especially over something as mundane as checking your voice mail.
