'"We discovered that if the I-Key touches a cellphone, outgoing or incoming calls have the potential to alter the electronic code inside the I-Key," Nissan spokesman Kyle Bazemore said. "The car won't start and the I-Key cannot be reprogrammed."'"

Bad, bad analogy! (Score:5, Informative)
The Model T had two different clutches, one for going forward and the other for reverse. When the forward clutch wore down and started slipping under heavy loads, one turned the car around to go up a steep hill. Or, if the brakes didn't work, you could use the reverse pedal to stop the car.
Perhaps one could say that Model Ts were so widely used because they were more reliable than horses. It's more probable that a horse would become sick and die than a Model T engine would need replacement.

Show me a car engine that can meet current emissions requirements without electronic controls while running on fuel that you can buy at your local gas station. You can't, because it simply isn't possible. Even diesels have computer controls these days.
Electronic controls are an absolute requirement for gasoline engines because of the fine level of control of air/fuel mixture and ignition timing required to burn the fuel efficiently and somewhat cleanly whilst not destroying the engine in the process.
One car I owned recently (a 1995 Chevy) had an 11:1 compression ratio and ran on 87 octane fuel (that's the lowest grade of gasoline available in most of the USA). Without electronic controls such as knock sensing, O2 sensor feedback, mass airflow measurement, and the precise control of both the quantity and timing of fuel injection and the timing of the ignition by a computer, it simply would have been impossible to reach the power level that engine developed (or even to drive at all with an 11:1 CR on 87 octane fuel without knocking holes in the pistons) and at the same time producing HC and CO emissions that were a fraction of the same size (5.7L V8) engine from ten model years earlier.
An easy example of how electronic controls have improved the reliability of modern cars is the elimination of the ignition distributor. Pretty much all modern cars do not have distributors now, because they were such a common point of failure for ignition systems that they made cars break down due to things like worn out cap and rotor, or burned points (going back to before 1975 when electronic ignition became pretty much mandatory). Take a look at the tune-up intervals in a modern car's maintenance schedule. It used to be you'd have to change half the ignition system out every couple of years - now the whole thing is good for at least 100K miles in most cases.
Without modern electronic engine controls, US cities would still be blanketed photochemical smog from vehicle exhaust, and people's cars would be significantly less fuel efficient and far less reliable.
Your statement that electronic controls are not a vast improvement over the previous mechanical and vacuum controls is patently incorrect.

I don't think it's the electronics per se, but rather the attitude creeping in from the computer industry. I've noticed it in other industries as well, such as television and phone service. Faults that wouldn't have been tolerated ten years ago are suddenly cropping up everywhere. People have become desensitised to failure with electronics because of computers. Sloppy QA because of the training/expertise/staff overlap with computers.
And at the same time, another problem is preventing this from being solved. People put up with it. The way capitalism is supposed to work is that if somebody fucks up, you can go with a competitor. But now it's trendy to complain and then forget about it until next time something goes wrong. Shitty mobile phone reception? Moan about it, but don't ask for your money back. Crashing computer? Complain to your neighbourhood geek, but don't demand a refund. Evil dictator in charge of your country? Re-elect the fucker!

The public want blingful features, the public are no longer mechanically literate, and the public will not vocally insist on reliable vehicles. This creates tremendous pressure on makers to offer stupid shite at a competitive price.
Even good features like electronically controlled automatic transmissions are often poorly engineered and are brutally expensive to replace when they fail.
As an aside, tool prices have remained quite low, and if you are the sort of person who isn't afraid to learn you can save many thousands of dollars by doing your own work. The money you save easliy buys good equipment you can use for a lifetime.
Never has an auto repair course at the local community college been a better value. You can free yourself from ever having to buy a new car, free yourself from being at the mercy of undertrained or unethical automobile repair outfits, and know the person who worked on your car gave a shit.
If you can understand computers, it isn't a great leap to understand other technology, and as usual the internet can help.

The electronics have given us more features and higher fuel efficiency. But still, there are times when it would be nice to make it all manual. Cars that you can't shift into neutral unless the battery is charged can be a pain to get off the road after an accident. If a wheel sensor goes bad, you ought to be able to turn them off and drive the car to a service station, instead of put-putting along at five MPH on the side of the parkway.

In any case, my understanding was that with most of these, the key leaves the factory with a fixed number, no two keys have the same number and you reprogram the car to recognise the key rather than reprogramming the key to work the car. This sounds to me like a simple case of bad engineering which was never considered when the key was designed.
The upshot is that Nissan will re-design the key so it's not affected by cell-phones, new cars will ship with the redesigned key and owners of existing cars will have to pay a small fortune to replace the keys because it's not a safety recall issue.

This is precisely why... (Score:5, Interesting)
This is precisely why, at least where I live, the cars you most commonly see are more than 15 years old OR are less than three years old.
The relative simplicity of cars even from the early 1990's, nevermind the 60's and 70's, is what allows them to stay on the road so long. They're easier to work on (no super-expensive diagnostic equipment needed in most cases), the parts are made of stronger metals (steel and iron instead of aluminum and plastic) and the electrical systems are more independent of eachother than in today's cars.
The electrical mess that is today's cars is probably the single largest contributing factor to people's desire to replace a car instead of repairing it. Electrical gremlins are one of the hardest problems to chase down in today's cars because everything is sensor this and computer that. The systems are not redundant in most cases, and the parts and skills necessary to fix the problem once its diagnosed can be cost-prohibitive.
In an age when everyone is rightfully concerned about greenhouse gas emissions and energy efficiency, why are we building cars that are very complicated, have a high energy cost to produce and go straight to the junkyard, on average, in less than 10 years?
The worst problem is that, with the exception of some of the more advanced engine control systems allowing better fuel economy, very few of these electronic 'improvements' actually make driving safer, better or more enjoyable.
I mean, as cool as it looks to wave an electronic key and have the car start, have we gotten to the point where a mechanical lock and tumbler are too hard to turn?
People got along for more than 100 years in cars without GPS systems telling them (in some cases incorrectly) to "turn right in 300 yards".
Even hybrid gas-electric cars are based on 80+-year-old tech. Diesel-electric submarines were built and operated with very little, and early on no computer support systems.
As with a great many things, I think it's time we take a good hard look at what we have, and attempt to simplify instead of further complicate.

The capacitive coupling of an antenna to a key could then be quite good at the 1-2GHz frequencies (0.5pF @ 2GHz => 150Ohms). That's a low enough impedance to power up a device (through its protection diodes) and cause it to reprogram itself due to noise on the inputs. It could actually even fry the poor little silicon device, if it rectified the voltage got up high enough (>5V) for any length of time.
It's not that hard a problem to prevent (put a filter on your inputs folks!), but I doubt the automotive key entry designers are normally thinking of transmitters at that power and frequency.

Oh, and a plane's directional sensor that the Mythbusters team sat next to a phone.
I'm an electronics engineer and have worked most of my life in aerospace equipment. Electronic equipment in airplanes are *very* sensitive, they are designed to work far away from everything. There's no sense in a directional sensor that only works inside the airport. That's why no one is allowed to use cell phones in an airplane.
Cell phones (at least some GSM phones) cause short bursts of *massive* amounts of EM interference
Define "*massive*". Would a trillion (or, in British units, a million million) times do? Well, it's pretty normal for inputs in electronic equipment such as radios and TV receivers to have -120 dBm sensitivity. That means one trillionth of one milliwatt. A phone with a 100mW signal has a hundred trillion times more power than the smallest threshold a radio or TV can detect.
Cell phones are designed to have enough power to send signals through one or two concrete walls and that's all. If they were more powerful than that, their batteries wouldn't last. OTOH, radio and TV receivers are designed to detect the most feeble signals possible. The combination of a so-so transmitter in a cell phone with a non-limited sensitivity on a TV or radio is what makes RFI happen.

(No doubt it was a vehicle confiscated from a drug dealer or something.) Trouble was, the car he bought had no key with it. He came into the dealer with the VIN hoping to get a replacement key issued. The parts man did a lot of manual searching, and catalog thumbing and told the man the cost of a new key would be $3000+! Seems not only a new key was needed, but a complete replacement of the main computer module for the car. I don't know when I have seen someone more disappointed and frustrated as the fellow who got such a good deal on the Lexus.
