What Google’s new digital car key sharing feature does
Google Wallet’s new digital car key sharing feature lets car owners give controlled, revocable access to their vehicles using a phone-based key, with role-based permissions and optional limits on driving behavior such as speed and acceleration so that each shared driver gets only the level of control the owner intends. After a recent Google system services update, the Google Wallet car key can now be shared from within the app with far more nuance than before. Instead of handing over a physical key fob, owners send a secure digital pass that lives on another person’s compatible Android device. That pass can be tuned for different situations—long-term co-driving, occasional borrowing, or short service visits—while keeping the original owner in charge of car key access control, device compatibility, and the ability to cut off access at any time.
How role-based permissions work: co-owner, guest, and service
Google Wallet now supports three permission levels for digital car key sharing: co-owner, guest, and service. A co-owner key mirrors the original, effectively acting as a full-access spare for a partner or primary driver. According to Digital Trends, “a co-owner gets full access, much like handing a spare key to a partner.” Guest keys are aimed at friends or family who only need partial access, such as borrowing the car for a weekend. Service keys fit valet or workshop scenarios, granting enough control to park, move, or test the car without unlocking full ownership capabilities. These role-based permissions make digital car key sharing feel similar to managing multiple physical keys, but with finer control and a clear separation between everyday drivers, occasional borrowers, and third-party services.
Speed, acceleration, and other limits for safer shared driving
The biggest leap in this update is the ability to apply custom restrictions to each shared Google Wallet car key. Beyond choosing a role, owners can set speed limits, acceleration limits, and even a cap on how loud the audio system can go, tailoring every digital car key sharing instance to the driver’s experience and the situation. For example, a guest key for a new driver in the family might include lower speed and acceleration thresholds, while a service key could limit both performance and in-car entertainment. These controls help reduce risk without needing extra hardware or separate driver profiles in the vehicle itself. The exact options vary by car model, but in every case, car key access control is shifting from a simple on/off toggle to a granular, per-driver configuration.
Sharing, revoking, and moving keys between devices
Sharing a Google Wallet car key starts in the Wallet app: you select the digital key, tap Share car key, confirm your identity, and choose a contact or app. The system then walks you through naming the shared key and reviewing its settings, which differ across vehicle brands and models. A passcode appears so the recipient can activate their key remotely on a compatible Android phone or, in some cases, a Wear OS smartwatch. The same update also makes it easier to move your own key between your devices, so your watch and phone can both unlock and start the car. Importantly, owners can revoke or change access at any time from Google Wallet, giving them flexibility for short-term lending, recurring guest use, or service appointments without losing long-term control over who can drive and how.
Supported phones, cars, and what this means for families
The digital car key feature currently supports Pixel 6 and later (including Pixel Fold), Samsung Galaxy S21 and later, and select other Android phones running Android 12 or newer, with some Wear OS devices gaining smoother sync as well. On the vehicle side, availability depends on the manufacturer, but brands such as Audi, BMW, Cadillac, Genesis, Hyundai, Kia, Lotus, Mercedes-Benz, Mini, Polestar, Porsche, Rivian, Tesla, and Volvo already offer compatible systems. For families, role-based permissions mean a shared car can have different digital keys tuned for each driver’s skill level and needs, from full co-owners to teens with capped speed and audio levels. For services, temporary keys with limited permissions help protect both vehicle and owner data. Overall, Google Wallet car key access control is moving beyond convenience into everyday safety and practical household management.
