There's nothing more frustrating than misplacing your car keys. Telsa might be able to help with that.
The company recently received approval from the Federal Communications Commission's office of engineering and technology to patent a new key fob for its electric cars, The Verge reports.
Perhaps the most notable feature of the new key is that it was tested for Bluetooth Low Energy which opens up the possibility that the key could directly sync with a Tesla vehicle or even function as a key finder.
Tesla did not immediately respond to requests for comment from CNBC.
Bluetooth technology is already used by iPhone and Android apps and could easily be applied to the existing technology.
