With a May 2026 Google system services update, Google Wallet is making digital car keys easier to share—by letting users assign roles like co-owner, guest, and service, plus specific limits on speed, acceleration, and even music volume.
If you use your Android phone as a car key, the next time you hand the keys over, you won’t have to guess how much access someone should have. A May 2026 Google system services update is rolling out now, bringing a clearer, more controlled way to share your digital car key inside Google Wallet.
The change isn’t just about sharing at all—it’s about choosing the kind of access you’re comfortable giving. Previously, sharing your digital car key in Google Wallet was pretty basic. Now the update introduces three distinct roles: co-owner, guest, and service.
A co-owner gets full access, the same idea as handing over a spare key to a partner. A guest role is more limited, built for lending your car to a friend or family member. The service role is aimed at mechanics or valet drivers, offering enough access to do the job without turning over full control.
Roles are only half the story. When sharing, you can also set specific restrictions depending on who the recipient is. Those limits include speed limits, acceleration limits, and even a cap on how loud the music system can go.
Sharing is done from Google Wallet: open the app, select your digital key, tap Share car key, verify with your fingerprint, and choose a contact. The other person then receives a passcode that lets them activate their key remotely.
The update also simplifies something many people do daily—moving keys between their own devices. If you use a Wear OS smartwatch alongside your Android phone, syncing your car key across both is now smoother, designed for the moments when you switch devices throughout the day.
For drivers who already rely on Google Wallet as their everyday key, the upgrade is straightforward: sharing is now more flexible, but also more deliberate.

So basically Google can control my car now? cool…
I don’t get why it needs roles like “service” lol. If I’m giving my car away for a day, shouldn’t it just be a single setting? Fingerprint passcode thing sounds like it’ll get annoying.
Wait are they saying you can limit music volume?? like why would my friend even need that. Also this sounds like it’s gonna mess up when you switch phones, like last time where my key didn’t sync and I was stuck outside for 20 minutes.
This is gonna be a privacy nightmare. People will share “guest” access and then somehow you’re responsible if they speed, because the app literally lets you set speed/accel limits. Also “service” for mechanics feels like car companies just want more data. I’ll stick to the actual key fob, sorry.
