The digital car key ecosystem is expanding. Code changes discovered in Apple's Wallet backend reveal that Indian automaker Mahindra will support Apple Car Key on future vehicles. The feature, introduced by Apple in 2022, lets users unlock, lock, and start a compatible car by holding an iPhone or Apple Watch near an NFC reader. Mahindra already supports Samsung Wallet digital keys for Galaxy devices, but native Apple integration marks a major step for the Asian and global market.
Why Digital Car Keys Are More Secure
Security of digital car keys is often underestimated. Unlike a physical key, a digital key stored in Wallet uses hardware encryption and biometric authentication via Face ID or Touch ID. Even if the phone is lost, Lost Mode instantly disables access. For Android users, the process is equally robust. A recent Engadget guide explains that smartphone-based digital keys are generally safer than traditional key fobs, thanks to cryptographic tokens and encrypted NFC communication.

What This Means for Drivers
With Mahindra joining the list of Apple Car Key supporters alongside BMW, Rivian, Kia, and Hyundai, the adoption of common standards like NFC and multi-device support will push more users to leave physical keys behind. For individual drivers and fleet managers, managing digital keys via Wallet simplifies temporary access sharing, a big plus for car sharing and rentals. As highlighted in the discussion on technology neutrality, digitalization is never neutral but offers powerful tools when used consciously.
