Do you often find yourself jealous of Tesla users and their digital car keys? These electric vehicles can be operated with a card or smartphone, making driving a more seamless and simple experience. It’s only a matter of time before this technology becomes more widespread. The proliferation is starting now that smartphone manufacturers like Apple and Samsung are beginning to offer these features to more of us. Enter the Android digital car key, the feature that will let you dump physical, cumbersome keys once and for all.

The whole concept is straightforward to understand. A digital car key is a feature that allows you to lock, unlock, and start your car using your smartphone. It works with NFC (Near Field Communication). This technology can help devices communicate within very short distances of four centimeters or less.

Once set up, Android digital car key allows users to put phones near supported car doors to lock/unlock them. Additionally, the user can place the phone on the car key reader to start the vehicle.

Google has been very clear about its expansion to use UWB (Ultra-Wide Band) technology, which would enable using Android digital car key without getting the phone close to the handle or digital car reader. Phones with UWB support include the Pixel 6 Pro, Pixel 7 Pro, Samsung Galaxy S21 Plus, Samsung Galaxy S21 Ultra, Samsung Galaxy S22 Plus, Samsung Galaxy S22 Ultra, and the Galaxy Fold 2, Fold 3, and Fold 4 devices.

Ultra-Wide Band makes it possible to use features like passive entry. Passive entry allows you to unlock cars when you get close to the car, turn the car on when you’re inside, and lock the doors automatically when you step away from the vehicle. All without ever taking your phone out of your pocket.

Which cars support it?

Don’t go trying this just yet! Chances are most of us can’t use Android digital car key just yet. Car manufacturers have yet to adopt this technology widely; only a handful of vehicles currently support Android digital car key.

For now, the only manufacturer genuinely supporting Android digital car key is BMW. However, Google has partnered with the Car Connectivity Consortium to bring this to other vehicles. Other CCC partners include General Motors, Honda, Hyundai, and Volkswagen. This means these manufacturers should start joining the party soon.

Additionally, BMW has also rolled out UWB support, so that’s nice to have. Needless to say, Android digital car key is taking its sweet time coming to market.

Android digital car key currently works with Pixel 6 series and Pixel 7 series devices. It also works on some Samsung phones. More specifically, a Samsung Galaxy S21 series device or newer should be able to use Android digital car key. Google also mentions some other devices running Android 12 or newer have access to the feature.

Can I use the Android digital car key if my phone is off

Current NFC and UWB technology is impressive and requires very little power. This is why Android digital car key can continue working “for a few hours after your phone’s battery has drained,” as per Google.

This is only the case if you don’t require the screen to be unlocked for Android digital car key to work, though. Unlocking the screen isn’t necessary by default, and you must change the settings to change this. Remember that if the Android digital car key requires the screen to be unlocked, it won’t work when the phone is off.
