Google is planning to expand its digital car key feature to more Android phones running version 12 or newer. Currently, only a few car companies support this technology, such as BMW and Hyundai (including the Genesis and Kia brands). Depending on the vehicle, you might need to activate the digital key using a physical key or code. Alternatively, some cars will require you initiate the process from the infotainment screen.
It's important to note that this is different from the remote or proximity-based lock controls you'd find from companies like Tesla - with this, your phone acts as a physical key that requires getting close to the door. On phones with ultra-wideband such as many recent iPhones and larger Galaxy S21/S22 models, you can unlock your car without taking the phone out of your pocket or using a smartwatch.
Sharing the digital car key between iPhone and Pixel platforms is a promising innovation because it eliminates the need for carrying around multiple physical keys. By enabling access to cars through smartphones, users have an easier way of granting temporary car access without having to hand over a physical key. Additionally, it simplifies the process of car ownership and sharing by allowing owners to quickly grant access to a car without any hassle.
Finally, it provides enhanced security since digital keys are encrypted and stored securely on the phone. This makes it much harder for potential intruders or thieves to get access to your vehicle. In short, this new feature is a convenient and secure way of accessing cars with just your smartphone.
