Tesla has hinted at its plans to support digital car keys through mobile applications with the latest update to its app. The new version, 4.52.0, contains code references to ‘Harmony Wallet Key Cards’ that draw attention to a significant change in the company’s approach to mobile device integration.

Key Takeaways

✓Tesla’s mobile app version 4.52.0 includes code references to ‘Harmony Wallet Key Cards’
✓System-level digital car keys are generally more reliable due to direct OS interaction
✓References in the app suggest initial testing on Chinese HarmonyOS devices
✓Functionality resembles Apple’s digital car key system introduced via Apple Wallet

Changes in Mobile Device Integration

The current Phone Key system operated through an app running in the background of a user’s phone and connected via Bluetooth. However, with system-level integration, digital car keys are often considered more reliable because they directly interact with the operating system and utilize secure hardware components.

Code within the application also includes direct references to HarmonyOS and Huawei Wallet, suggesting that this new support will likely be tested first on Chinese market devices using HarmonyOS. This is a common strategy for Tesla as it usually employs China’s market to test new software solutions before rolling them out globally.

Digital Keys in HarmonyOS

Although the app doesn’t directly mention Apple Wallet or Google Wallet, the functionality that emerges closely resembles Apple’s digital car key system introduced via Apple Wallet in 2020. This system allows compatible vehicles to lock, unlock, and start using NFC, Bluetooth, or ultra-wideband (UWB) technology from an iPhone or Apple Watch.

With the Secure Enclave hardware security module on these devices, digital keys are stored safely and securely, offering a fast and secure user experience. Tesla’s new direction hints at its readiness to support such hardware-based digital wallet features soon.

Further Integration with iOS

Closer integration with Apple’s ecosystem could signify future expansion of this step in the coming periods. Additionally, Tesla continues to make efforts towards improving user experiences, especially in the competitive electric vehicle market. Rivian recently announced support for digital car keys through both Apple Wallet and Google Wallet earlier this month.

With the 2025.46 software update, this support enables Rivian users to use system-level digital keys. Similar integrations from other manufacturers like Porsche, Toyota, and General Motors are also in consideration.
