Carrying a set of bulky key fobs in the current era where a car key contains a lot more functions than just locking and unlocking the car could be pretty cumbersome, but that might soon be a thing of the past. Instead, automakers like Tesla, Jaguar and even Tata are offering customers alternative options such as a key shaped like a credit card without buttons or even an activity band one can wear on their wrist to access their vehicles. American tech giants, Google is working with car manufacturers to develop a new digital car key for their latest operating platform, Android 12. With this feature, one will be able to lock, unlock and even start their car from their phone.

At present, Google has not provided us with the details of how this technology would work. Still, a basic explanation from Google suggests that Near Field Communication (NFC) and Ultra Wide Band (UWB) radio technology would be used. It basically means that if your car is NFC compatible, you could just walk up to your vehicle and tap the phone to your door to lock or unlock your vehicle. In the case of the UWB technology, you can walk up to your car with your phone in the pocket, the car will automatically recognize the digital key that will help you lock or unlock your vehicle.  Google has also stated that you can securely and remotely share your car key with friends and family if they need to borrow your car.

At the 2021 I/O developer conference, Google has stated that “Starting later this year, digital car keys will become available on select Pixel and Samsung Galaxy phones. We’re working with BMW and others to bring this to their upcoming cars.”
