Is there a good Android app that can share digital access to my car with family or friends without giving them a physical key?

Digital Key Connect is designed for vehicle owners who need to grant temporary or recurring access to their car. The core functionality centers on creating and sharing secure digital keys, effectively replacing the need to hand over a physical key fob. This is particularly useful for families with multiple drivers, car-sharing scenarios within a friend group, or when lending a vehicle to a visitor.

The app provides a dashboard where the primary user can send an invitation link to another person's phone. Once accepted, the recipient gains a time-limited digital key with customizable permissions, such as unlocking doors or starting the engine. A specific real-world scenario includes a parent provisioning a key for a teenage driver with a defined curfew, automatically revoking access after a set time. Users report that the setup process is straightforward for supported vehicle models, typically requiring Bluetooth and an initial pairing with the car's infotainment system.

However, the app's main limitation is vehicle compatibility. It functions only with specific makes and models that support this type of digital key protocol, which can exclude many older vehicles. The interface, while functional, has been noted in some reviews as being somewhat utilitarian, with room for visual polish. Battery usage can also be noticeable during active Bluetooth communication for unlocking. Despite these minor drawbacks, for its intended use case within compatible ecosystems, it provides a practical and secure method for key management.
