At the Mobile World Congress in Barcelona on Monday, BMW showed off a smartphone-enabled car locking and unlocking experience.
BMW's Digital Key will be available this July for BMW car owners who have a Samsung phone. Through the BMW Connected app, the Digital Key can open your car straight from your phone. Once you're in the car, placing the phone on a wireless charging pad can even start the engine if you get really fancy.
To alleviate some of the pressure of completely losing access to your car, up to five other people can have a "copy" of your key, also on their Samsung smartphone. (This rollout will be very limited initially.)
The digital key is a snazzy new feature, but most people will still need physical keys to drive around, even if the smartphone is truly becoming an all-in-one device.
But soon, maybe, the everyday search for your car keys will be gone, to be replaced with new ones: Just don't lose your phone or drain the battery.
