Tesla May Allow iPhone Users to Use Apple Wallet as Digital Car Key

According to reports, Tesla is planning to enable iPhone users to control their vehicles directly through Apple Wallet, eliminating the need to open the Tesla app. Owners will be able to lock, unlock, and start their cars using a secure digital key stored on their iPhone—without relying on background app activity or continuous Bluetooth connections. This potential integration leverages Apple’s Car Key system, which combines NFC, Bluetooth, and ultra-wideband (UWB) technology to support features like Express Mode for instant access. Notably, the digital key can continue functioning for several hours even after the iPhone’s battery has been depleted.

Currently, Tesla owners can already use their smartphones as digital keys via the Tesla mobile application. However, this method occasionally suffers from reliability issues due to its dependence on stable Bluetooth connectivity and active background processes. By integrating vehicle access directly into Apple Wallet, Tesla—under the leadership of Elon Musk—aims to deliver a more seamless, reliable, and secure user experience. The digital key would be stored in the iPhone’s Secure Enclave, a protected hardware component designed to prevent unauthorized access and duplication. This move aligns with a broader industry trend, as automakers increasingly adopt smartphone-based key solutions to enhance both convenience and security.

It's worth noting that Apple’s Car Key framework was first introduced in 2020 and has since been adopted by several prominent EV manufacturers, including Rivian and select General Motors models. The platform supports advanced capabilities such as Express Mode, enabling car access without unlocking the phone, and Power Reserve, which keeps the digital key operational for up to five hours after the iPhone powers down. Additionally, ultra-wideband (UWB) technology enhances security by offering precise spatial and distance detection, significantly reducing the risk of relay attacks compared to traditional Bluetooth-based key systems.

Nevertheless, implementing Apple Wallet integration could present challenges for Tesla, including hardware limitations, stringent security requirements, ecosystem fragmentation, and compatibility across its diverse global fleet. For instance, not all Tesla models are equipped with the necessary hardware to support Apple’s Car Key functionality. Furthermore, Apple’s licensing and certification procedures may slow down the deployment timeline, especially for a company with millions of vehicles on the road.
