Cell phones are capable of doing just about anything these days, so they might as well be used to unlock your car doors and start your engine.

That was Sharp’s logic when it teamed up with Japanese mobile company NTT DOCOMO and Nissan to manufacture a cell phone that you can program to electronically control engines and door locks.  Essentially, Sharp installed an existing piece of technology, or Nissan’s Intelligent Key, into a phone.

These technologies seem so well suited that it’s surprising that the latest iPhone didn’t include a feature such as this.  Gizmodo claims that this integration was a long time coming.  Apparently, the filthy rich, hackers, and the Chinese have pretty much all had this idea.  U.S. drivers should have access to this technology early in 2009.  However, if you’re willing to pay for technology such as this, make sure you don’t neglect to invest in a good auto warranty. After all, you don’t want to end up paying unnecessary repair expenses down the road.
