If your phone lives in your pocket and your car key lives inside Google Wallet, the two are about to behave more like grown-ups. Google’s May 2026 system services update — rolling out as part of recent Play services work — adds three distinct permission roles for shared digital car keys and makes it simpler to move keys between your devices.
Three roles, finer limits
Owners can now share a digital key as a co-owner, guest, or service user. Co-owners get a full copy of the original key (think of handing a partner a spare fob). Guests are intended for friends or family and can be restricted: you can cap top speed, limit acceleration and even restrict the car stereo’s maximum volume. Service is a temporary, tightly scoped setting for valets or mechanics so they can drive or move the car without full access.Sharing is handled inside Google Wallet: open the app, tap the digital car key, choose Share car key, name the shared key and review vehicle-specific settings. Google asks you to verify ownership (biometrics like a fingerprint), then you pick a contact or compatible app to share with. The recipient uses a passcode to activate the key; depending on the car and setup they may need to be nearby to finish activation.
This isn’t just permission theatre — some of the settings are granular and depend on the vehicle maker. That’s important because support for digital keys still varies by manufacturer. Automakers offering the feature include Audi, BMW, Cadillac, Genesis, Hyundai, Kia, Lotus, Mercedes-Benz, Mini, Polestar, Porsche, Rivian, Tesla and Volvo, among others.
Your phone, your watch, your other device
The update also smooths cross-device management. Moving a key between your own Android devices — for example from phone to another phone or to a Wear OS smartwatch — is easier than before. That’s handy if you prefer leaving your phone at your desk and walking to the car with a smartwatch on your wrist.Google bundled these changes into the May system services push (and some reports tie elements to Play services v26.20). The rollout is gradual, so not everyone will see the new roles immediately.
Compatibility and cautions
Digital car keys in Wallet work on Pixel phones (Pixel 6 and later, including the Pixel Fold), Samsung Galaxy phones (S21 and later) and a range of other Android devices running Android 12 or newer. But keep in mind: availability for a specific model still depends on the carmaker’s implementation, and behaviors (like whether a shared user must be near the vehicle to activate the key) can vary.There are also practical questions people raise: what if a service is discontinued, or the cloud component changes? Those concerns are worth keeping in mind before you hand out access to your vehicle — share only with people you trust and check your carmaker’s guidance about digital-key recovery and revocation.
As phones and cars trade more responsibilities — a trend that’s reshaping vehicle software and dashboards — richer key controls make sense. For readers tracking how vehicle software is evolving, this sits alongside broader shifts such as the move toward embedded automotive platforms and recurring hiccups in in-car Android integrations (an area that recently drew attention when an Android Auto update caused trouble for some Galaxy and Pixel owners).

If the new sharing options appear on your phone, take a moment to explore them and, if you experiment, do it with a trusted test user before passing keys to someone who’ll be driving your car on the freeway.
