The Volvo 2017 model will not be equipped with the most common thing that cars have - a key hole. It won't have this opening since this modern car uses a smartphone to gain entry instead of a car key. Keys are already getting obsolete.

The new sedan made by the Swedish car maker will be launched later this year. An owner of this car model will no longer need a key, except if he still wants to enter his car the old way.

Volvo is not the only one adapting this modern innovation. Ford, the American car maker has provided car keys to just two of its latest truck models. In the next couple of years, it may opt to completely take car keys out of all its car and truck line up.

There is a speculation that the European auto maker will also abandon the use of the wireless key fobs that have already replaced conventional car keys.

"Mobility needs are evolving, and so are our customers' expectation to access cars in an uncomplicated way," said Henrik Green, Volvo vice president.

To be able to use this new car entry system, new Volvo car owners will have to download a smartphone app designed to unlock, lock and start the cars using Bluetooth.

If an owner has a number of Volvo cars with the same car access feature, he can use the smartphone app for all the cars, eliminating the need for several access keys.

Other car makers are already using apps that allow car owners to remotely lock, unlock and start their cars using smart phones, but they still need a physical key or a key fob to drive their cars.

With the smartphone app of Volvo, absolutely keyless cars are now possible. This innovation is a great boon to those who always lose their car keys somewhere.
