Google Wallet update adds guest and service roles for digital car keys

Google has rolled out a May 2026 system services update that adds new “guest” and “service” roles to digital car keys in Google Wallet, making it easier to share limited vehicle access with trusted contacts [1].

Key takeaways

• New roles—co‑owner, guest, and service—let owners assign different levels of car access [1].
• Keys can be shared from the Wallet app to a contact after fingerprint verification, with a passcode for activation [1].
• Users can set driving‑condition limits such as speed or music volume when sharing [1].
• The update also syncs keys across phones and Wear OS smartwatches [1].
• Larger‑screen Android devices receive an expanded Play Store experience as part of the same update [1].

New sharing options in Google Wallet

The update builds on the existing ability to share digital car keys, which has been available for more than three years, by introducing role‑based permissions. A “co‑owner” retains full control, while “guest” and “service” roles restrict what the recipient can do, mirroring the way physical fobs can be handed over with limited rights. To share a key, users open Google Wallet, select the digital key, tap “Share car key,” verify ownership with a fingerprint, choose a contact, and then set any desired limits on speed, acceleration, or even the car’s audio system. The recipient receives a passcode that unlocks the key when they are nearby [1].

Cross‑device key management and other enhancements

Beyond role‑based sharing, the update simplifies key access across a user’s ecosystem. The same digital key can be used on a phone and on a Wear OS smartwatch, ensuring owners can unlock their vehicle from whichever device is most convenient. The system services update also improves the Play Store for tablets and foldable devices, showing more content on larger screens, and adds a feature to preserve daily game streaks, though details on the latter remain unclear [1].

Why it matters

By allowing granular permissions, Google’s update addresses a common concern: how to let others drive a vehicle without handing over a physical key that grants unrestricted access. The ability to set speed or audio limits adds a layer of safety for families and service providers. As more drivers adopt digital keys, such role‑based controls could become a standard expectation, influencing how automakers design future key‑in‑phone solutions. The rollout also signals Google’s broader push to make Android’s ecosystem more cohesive across devices, especially for larger‑screen form factors. Users will need to install the update via Settings > Google services > System services to take advantage of these features [1].
