Nissan Warns Drivers: Don't Put Mobile Phones Near Our Keys

from the well-that's-one-way-to-stop-driving-while-yakking... dept

Nissan is going around warning a bunch of US drivers of either the Nissan Altima or the Infiniti G35 to be careful with their mobile phones. However, it's not, as you might expect, about driving while using those mobile phones. Nope. It's about keeping those mobile phones away from the car keys that open and start the cars. Like many newer cars, these cars use a wireless key system. Unfortunately, they're discovering that mobile phones receiving calls while in contact with the keys can scramble the electronic code on the keys... making them into useless paperweights. This would seem like a pretty big problem -- and simply telling drivers to keep their phones away from their keys isn't likely to work very well, considering phones and keys very often end up together in people's pockets or purses.

    Re: Nissan Warns Drivers: Don't Put Mobile Phones

    Nissan says their remotes use Wi-Fi technology, not line-of-sight infra. Different technologies one is light spectrum the other is RF.

    Whether the Freqs of the Mobiles are in the same RF range might not have anything to do with it, most prob. its the induction field around the RF unit. On VHF its quite weak, but theoretically enough to cause damage to circuitry without shielding (HF is quite a different story as anyone with some HamRadio experience will tell you, a decent HF antenna has enough voltage to kill a grown man).

    The question we should be asking is... why isn't there any shielding around the circuitry of the remote? Surely the FCC specifies such shielding for these devices.
