Remotely unlock and start your car - coming soon to a smartphone near you

Owners of most new (2011) General Motors (GM) vehicles will be able to control their vehicles from their smartphones, the company announced July 22.

In the coming months, the Detroit-based automaker will roll out apps for owners of new vehicles across its entire portfolio, which includes Chevrolet, Cadillac, Buick and GMC.

Using the apps, drivers will be able to activate all of the features on a traditional key fob from anywhere, including remote start, horn and lights and door locks, as well as some new features such as diagnostic information.

GM says that the technology could be useful for someone rushing to catch a flight who forgot to lock their vehicle, or a family attending an event on a hot summer day who wish to ensure that their car is cool before they return to it.

It will also display a vehicle "health report" with diagnostic information such as fuel tank level and range, remaining oil life, current and recommended tire pressure and lifetime average miles per gallon.

The technology, which was originally displayed for use with the Chevrolet Volt earlier this year, will run on iPhone and Android systems and uses OnStar, which is available in the US, Canada and China.

OnStar's Chris Preuss said that the "technology empowers drivers to make decisions about their travels well before they enter the vehicle, meaning their full attention can stay where it needs to be – on the road ahead.”

GM is pushing hard to advance the handheld products it offers, particularly as it faces tough competition from Ford, which has announced a cloud-based link with its in-car computer system, SYNC.

In June, both automakers said that they will integrate Google Maps into their vehicle navigation devices, although Ford has yet to announce an official remote app for its cars.
