Introduction: The Next Step Toward a Phone-Based Driving Experience
The relationship between smartphones and vehicles continues to evolve, transforming the traditional car key into a digital experience built around convenience, security, and connectivity. Apple appears ready to expand this vision even further, with hidden references inside the latest iOS 27 beta suggesting that two major automakers, Xiaomi and Lucid Motors, could soon join the Apple Wallet Car Key ecosystem.
The discovery points toward a broader future where drivers may rely less on physical keys and more on their iPhone or Apple Watch to control essential vehicle functions. While Apple has not officially announced launch dates or supported models, the presence of these references inside iOS code indicates that new partnerships may be approaching.
Apple Wallet Car Key Could Welcome Xiaomi and Lucid Motors
According to code discovered inside the latest iOS 27 beta, Apple appears to be preparing support for Car Key functionality from Xiaomi and Lucid Motors. The findings were reported after analysis of iOS 27 beta 3 code, which reportedly contains references connected to these two automakers.
The discovery was made by Aaron Perris, who shared the findings with MacRumors after examining the internal software framework. Hidden code references often provide early clues about upcoming features, although they do not always confirm immediate availability.
Apple has historically used software updates to quietly prepare support for future products and partnerships before making official announcements.
Lucid Motors Partnership Was Announced Earlier, But Updates Were Limited
Lucid Motors is not a completely new name in Apple’s Car Key plans. During WWDC 2025, Apple announced that Lucid vehicles would eventually support the feature. However, since that announcement, details about availability, compatible models, and launch timing have remained limited.
The appearance of Lucid-related references inside iOS 27 suggests that development may still be moving forward behind the scenes.
Lucid Motors, known for its luxury electric vehicles and advanced technology focus, represents the type of brand that fits naturally into Apple’s connected ecosystem strategy.
Xiaomi Could Become a New Player in Apple’s Automotive Ecosystem
The possible addition of Xiaomi is more surprising because the company had not previously been publicly linked to Apple Wallet Car Key support.
Xiaomi has rapidly expanded beyond smartphones into electric vehicles and smart mobility products. Its entrance into Apple’s Car Key ecosystem would represent a significant step toward deeper integration between Chinese automotive technology and Apple’s services.
The company’s electric vehicle ambitions have positioned it as a growing competitor in the global EV market, making digital key compatibility an important feature for future customers.
No Confirmed Vehicles or Launch Dates Yet
Although references were found in iOS 27 beta code, Apple has not revealed which Lucid or Xiaomi vehicles will support Car Key.
Several possibilities remain open. Support could initially arrive only for newer models equipped with specific hardware, while older vehicles may not receive compatibility.
It is also unclear whether the feature will become available immediately after iOS 27 launches publicly or whether Apple and automakers will activate support later through server-side updates.
iOS 27 Beta Suggests a September Expansion Window
The timing of the discovery could indicate that Apple is preparing these partnerships for the public release of iOS 27, which is expected around September.
Apple frequently introduces new ecosystem features alongside major operating system updates, especially when those features depend on new partnerships or hardware integration.
However, beta code alone does not guarantee that a feature will launch immediately. Companies often include unfinished capabilities during testing phases before final decisions are made.
Volkswagen May Also Join Apple Wallet Car Key Expansion
The possible Xiaomi and Lucid additions come shortly after reports suggested that Volkswagen had been added to Apple’s backend list of supported or upcoming Car Key partners.
This indicates that Apple may be accelerating expansion of its digital vehicle key platform across multiple manufacturers.
A wider range of supported automakers would strengthen Apple’s position in the connected vehicle market, where technology companies are increasingly competing to become the central interface between drivers and their vehicles.
How Apple Wallet Car Key Works
Apple Wallet Car Key allows users to store a vehicle key digitally on their iPhone and Apple Watch.
Instead of carrying a traditional key fob, drivers can use their Apple device to:
Lock and unlock their vehicle
Start compatible cars
Access proximity-based entry features
Control certain vehicle functions remotely
The exact experience depends on each automaker’s implementation and the technology installed in the vehicle.
Express Mode Makes Digital Keys More Convenient
One of the most important features of Apple Car Key is Express Mode.
With Express Mode enabled, users can unlock or start their vehicle without unlocking their iPhone with Face ID, Touch ID, or a passcode.
This creates a faster experience similar to using a traditional key while maintaining the advantages of digital authentication.
For daily drivers, this removes one of the biggest barriers to smartphone-based vehicle access.
Digital Key Sharing Changes Vehicle Ownership Experience
Apple also allows users to share digital car keys with other people through Messages, Mail, and AirDrop.
This feature could be useful for families, employees, rental situations, or temporary vehicle access.
Instead of physically handing over a key, owners can digitally authorize another person to use the vehicle.
This represents a major shift in how access control works in modern transportation.
What Undercode Say:
Apple’s expansion of Car Key support represents a much larger technology shift than simply replacing a physical key with an iPhone feature.
The automotive industry is becoming increasingly software-driven.
Vehicles are no longer only mechanical machines. They are connected computing platforms with operating systems, cloud services, applications, and digital identity systems.
Apple understands that controlling access to a vehicle creates a powerful position inside the user experience.
The company already dominates smartphone ecosystems through iPhone and Apple Watch adoption.
By integrating deeper with vehicles, Apple can extend its ecosystem beyond personal devices and into daily transportation.
The possible Xiaomi partnership is especially interesting because it connects two major technology markets.
China has become one of the most competitive electric vehicle markets in the world.
Companies like Xiaomi are attempting to challenge traditional automakers by combining software, artificial intelligence, and consumer electronics expertise.

Lucid Motors represents a different strategy.
Lucid focuses on premium electric vehicles with advanced engineering and luxury positioning.
Apple users who purchase high-end EVs are likely to value seamless digital experiences, making Car Key integration a natural fit.
However, digital keys also introduce cybersecurity concerns.
A physical key requires physical possession, but a digital key depends on software security, authentication systems, and communication protocols.
Automakers must ensure protection against unauthorized access, account compromise, and relay attacks.
Apple’s security infrastructure provides advantages, but vehicle manufacturers must also maintain strong security standards.
The future of car ownership will likely involve more software-based features.
Drivers may eventually manage vehicles through smartphones, smartwatches, cloud accounts, and biometric authentication.
The competition will not only be about horsepower or battery range.
It will also be about who provides the best digital ecosystem.
Apple Wallet Car Key could become an important part of that competition.
