Apple is preparing to add car key support for Lucid and Xiaomi vehicles, as indicated by code in the third developer beta of iOS 27. The code references "LCID" and "XIA1," which appear to correspond to Lucid and Xiaomi. Apple Car Key allows users to lock, unlock, and start compatible vehicles with their iPhone or Apple Watch. Lucid Motors was previously announced as one of 13 brands that would "soon" gain car key support at WWDC 2025. Xiaomi's inclusion is new, marking a significant tie-in with Apple's ecosystem despite their smartphone rivalry. Xiaomi has rapidly expanded into electric vehicles with models like the SU7 and YU7. This isn't the first time code has hinted at car key support before an official announcement, as seen with Volkswagen and General Motors. The code doesn't confirm specific compatible models or an exact launch date. However, its presence in a live beta suggests Lucid and Xiaomi support may arrive relatively soon.
