Overview
- Reverse-engineering of Tesla app v4.52.0 surfaced references to “Harmony Wallet Key Cards,” attributed to Huawei’s HarmonyOS and Huawei Wallet.
- The findings indicate a move away from Tesla’s Bluetooth-dependent Phone Key toward keys stored at the system level using secure hardware.
- The code does not mention Apple Wallet or Google Wallet, though the implementation resembles Apple’s Car Key approach on iPhone and Apple Watch.
- HarmonyOS targeting points to a plausible China-first rollout, matching Tesla’s history of testing new software features in that market.
- Rivian has already added native Apple and Google wallet keys, with recent reporting suggesting Porsche, Toyota, and GM are pursuing similar support.
