Code spotted in the third developer beta of iOS 27 suggests that Apple is preparing to add car key support for Lucid and Xiaomi vehicles, and that the feature could be nearing launch. The code references the identifiers "LCID" and "XIA1," which appear to correspond to Lucid and Xiaomi respectively. With an Apple car key, drivers can use their iPhone or Apple Watch to lock, unlock, and start a compatible vehicle instead of relying on a traditional key fob.
