So You Want to Unlock Your Car Like You‘re Living in the Future? Let Me Show You How with Android 12.
You know the feeling. Rushing out the door, you frantically pat down your pockets only to realize you have no idea where your car keys ended up this time. But what if you could leave that keyring behind forever by using your phone instead? Well, if you have an Android 12 device and a compatible set of wheels, I’m here to help you make this keyless dream reality.
See, digital car keys use short-range wireless signals to pair your phone with your car. This lets you unlock the doors or even remote start the engine without taking out a physical key. And major players like Google along with auto manufacturers have committed to bringing this functionality mainstream. With capabilities expanding thanks to ultra-wideband (UWB) technology and new standards like the Android Digital Car Key API, over 24 million digital key-compatible cars are forecasted to ship annually by 2025.
So in this guide, let me walk you through exactly how digital car keys work, the Android 12 and auto models supported so far, step-by-step setup instructions, usage tips from my real-world testing, security considerations, where things are heading next – and ultimately how you can be unlocking your car with just your smartphone very soon. Shall we?
How Do Digital Car Keys and Android 12 Phones Communicate?
These slick virtual keys use short-distance wireless communication to pair your specific phone with your car’s onboard computer. This allows customized actions like unlocking doors or starting the engine once the vehicle recognizes your device. There are two main methods used:
NFC – Yes, the same near field communication tech used in tap-to-pay mobile payments. You simply hold your device against a reader on the car door handle to unlock it when in range. Maximum range is usually 4-5 cm.
UWB – Ultra-wideband sends more data over increased bandwidth for better precision. With UWB, doors can unlock automatically as you approach within 10 meters. And because it can pinpoint direction and distance via timing signals, UWB powers next-gen features like holding up your phone to start the engine before even touching the car. Slick, huh? UWB is the way of the future but still maturing on the compatibility front.
Now at the software level, digital car keys to date have mostly used proprietary manufacturer platforms requiring their own unique apps. But Google is pushing for wider standardization of how the keys themselves are secured and transported. Enter the Android Digital Car Key API – currently being developed to securely house credentials directly within supported smartphone hardware. We should see this adopted more moving forward.
Bottom line – NFC for simple unlocking, UWB for advanced automation, and standardized APIs for smoothed out integration. That foundation sets the stage for optimized convenience and functionality. Read on for how to enjoy it yourself.
Which Cars and Phones Support Digital Key Right Now?
The digital car key landscape is rapidly evolving with support expanding quickly. As of early 2023, here are some of the popular car models confirmed compatible with Android 12-based Samsung Galaxy, Google Pixel, and other Android phones:
| Car Make | Compatible Models |
|---|---|
| BMW | 3 Series, 5 Series, X5, X6, X7 models & more from 2020 model year onward |
| Ford | Mustang Mach-E |
| Genesis | Genesis G90 sedan & GV60 SUV |
| Hyundai/Kia | Sonata, Elantra, Carnival & more 2022+ models |
| Polestar | Polestar 2 EV |
But it goes well beyond this list too. Google has partnered with leading automakers to bring built-in digital key functionality across phones running recent versions of Android. So you’ve got plenty of options whether using a Galaxy S22, Pixel 7 Pro or other flagship device. Now let’s get yours set up.
How to Set Up and Start Using Digital Car Keys on Your Phone
The three main methods for enabling a slick virtual key on your Android 12 phone are:
- Your car manufacturer’s own official app
- Your ride’s digital console and menu system
- Third-party apps like KeyConnect offering wider compatibility
Let me share the step-by-step process to connect things up with each avenue:
Using Your Automaker’s Dedicated App
For example, BMW has the BMW Connected app with digital key support for many 2020+ models.
[Screenshot of BMW Connected app download page]Here’s how to enable it for your compatible ride:
- Download the BMW Connected app from Google Play store
- Open the app and set up your ConnectedDrive account
- Head to the Digital Key option and pick your eligible vehicle
- Follow the on-screen pairing prompts and tap your phone against the door handle reader
- All paired up! Add a shortcut too for fast access anytime
Using In-Car Display and Menus
If your vehicle screen supports it, pairing occurs through the settings:
- Select Digital Key option on the console
- When asked, choose your Android phone to set up with
- Sign into your Google account if prompted
- Accept the activation code shown on-screen
- Tap your device against the door to successfully link with your car‘s computer system
Using a Third-Party App Like KeyConnect
For models without their own official apps, KeyConnect bridges compatibility gaps:
- Visit KeyConnect’s site and enter your vehicle VIN # to confirm app compatibility
- Download KeyConnect from Google Play if supported
- Launch the app on your phone and pick your car details
- Follow the pairing and setup steps inside the KeyConnect interface
And that’s it for virtually pairing your phone instead of a traditional key!
Now the fun starts using it to lock and unlock your connected ride…
Unlocking Your Car and Customizing Your Digital Key
After configuring your digital key using one of the methods above, your Android phone essentially clones your physical key’s wireless authorizations.
So if your car uses NFC signals, you’ll now just tap the marked area on the door handle when in close proximity to unlock it – hearing that satisfying click signaling entries open. No need to even take my phone out of my pocket!
For UWB models supporting longer 10 meter ranges, doors conveniently unseal automatically as I walk up hands-free without any taps required thanks to precision directional mapping. I just tested this on my friend’s fancy new Genesis G90 which definitely made me jealous. Either way, it feels super futuristic!
Beyond that basic unlocking, many digital car apps let you customize more access controls and settings:
[Screenshots showing BMW app custom permissions]Like defining maximum vehicle speed limits for valet or teen driver modes. Handing out customizable digital guest keys with permissions that automatically expire. Even remote features to check battery levels, find parking locations, activate climate controls or in some cases start the engine and mirrors before even entering within miles.
As you can see, functionality scales up nicely as you dig in. And the convenience factor of ditching that keychain can’t be overstated day to day. But worth covering briefly too are…
Some Security Considerations to Keep in Mind
Make no mistake – digital car keys and connectivity introduce great features. But also potential security considerations, just like any wireless access system that can bypass physical barriers.
The good news is encryption has vastly improved requiring multiple authentications – like biometrics or PINs – from your specific paired device before unlocking sensitive commands.
Manufacturers claim relay signal attack risks are low too thanks to ultra-wideband and NFC protocols making long-distance amplification difficult. Though always good to be cautious with early tech.
My advice? Take basic precautions like:
- Enabling maximum encryption in your car & phone settings
- Using guest keys temporarily rather than sharing main key access
- Testing for any suspicious unlinked devices showing up when reviewing paired connections
- Carrying a spare physical key as backup if your phone ever dies
Stay diligent and you’ll reap maximum security upsides.
What Does the Future Hold for Digital Car Keys?
We’re still early on this digital car key journey with the convenience and capabilities ramping up quick. Beyond plans to expand cross-compatibility to more Android phone and car models, expect integration to deepen across:
Next-generation UWB – New ultra-wideband specs will keep stretching the operation range possibilities while strengthening directional precision and reliability for advanced automation functions or AR dashboards.
Wearables support – Google and Samsung are exploring how virtual car keys can securely live directly on smartwatches, fitness trackers or digital wallets for even more convenience tapping your wrist to unlock.
Autonomous driving ties – Self-driving ridesharing fleets could sync permissions through your personal virtual car key. Imagine summoning a robotaxi from your phone then seamlessly entering and controlling it using integrated digital credentials.
Multi-factor authorization – For sensitive actions like driveaway consent, digital keys could require layers like biometrics, PINs, or geofenced prompts for more security.
In other words, seamless phone-based access to our vehicles is fast becoming the new normal thanks to initiatives across the tech ecosystem making experiences more unified.
