If biometrics becomes cheap enough to use as a car key, then presumably it will also be possible to add people to the list of allowed users, via secure data transfer. Whatever scheme is used, biometrics or other, I think it preferable to have the key itself be battery-free. And this is very doable these days.
As to this, it made me chuckle:
"Biometrics have the same limitations, and may also have problems when the car is covered in ice and snow. You wouldn't want to damage the sensor scraping off the ice."
I used to own a Fiat 124 Sport back in my school days. I learned to rub the palm of my hand on the key slot, in snowy days, to thaw out the tumblers. So mechanical keys aren't immune to this problem either. Optical wouldn't be immune either. But NFC should be.
...did this 16 years ago with his BMW. Not only unlocked and started the car, but drove it remotely while viewing the dash cam. Now that could be a top selling app!
In reality, though, I can see a smart phone key as being an accessory for those who want it, not the primary key. Believe it or not, not everyone has or wants a smart phone. Also, this approach may work OK, until someone else needs to drive the car. Would you give them your phone?

Electronics and software are the luxuries for automotive not a necessity. The car's primary function is transport. Rest all is nice to have but notmandatory. But liked the idea tracking cars inhe parking of malls
Yes, and they are getting away with it!...imagine buying a blue BMW, you like it, brag about it to your friends, buy another one for your spouse...and then one day a message appear on your dashboard: pls upgrade engine software...with hesitation you do it...after that the software upgrade changes the color of your car into green and red...the dashboard get's crammed with extra icons that you don't need and can't read anymore (too small font and white in color)...and the gear shift is now in the ceiling!...and you can't go back to the previous version although it was just a software update...this is what you get from Apple today
Another issue is software upgrade, what if you can't open the car after the upgrade?...this is not as far fetched as you might think...I have recently upgraded my iPhone and it changed the colors, ring tone, and display, most of these "improvements" can't be changed, basically their created a teeneger version of my phone without me agreeing to it!...the phone is not user friendly anymore and I can't go back to the previous version!...Kris
I think this would just fall in line with the practice of trying to constantly innovate. They probably know that there's no market, but every time they explore something like this it opens new doors and areas to explore.
I agree. With the fast turnover rate of cellphones right now (2 year contracts are seen as a long time to own a phone!) combined with the fact that your phone could then be possibly used as an entry point for thieves leaves me rather unexcited about the prospect.
Biometrics would be great, but something that drops into my wallet would be ideal I hate carrying my keys, I won't go anywhere without my wallet though.
