Apple Car Key Support for GWM Tank Spotted in Wallet Backend Code

Code changes found in Apple's Wallet backend suggest that Apple Car Key support for GWM Tank vehicles may be in development, MacRumors reported last week. None of Great Wall Motor's four current Tank models, the 300, 400, 500, or 700, support the feature today, MacObserver reported last week.

The discovery is the third code signal pointing to Apple Car Key expansion this month. Earlier this month, identifiers "LCID" and "XIA1" appeared in the third developer beta of iOS 27, pointing to planned support for Lucid and Xiaomi vehicles, MacRumors reported. The Tank reference came separately, surfacing in Wallet backend infrastructure rather than a live OS beta a distinction that matters for understanding where GWM stands in the queue.

For Tank owners, the code changes nothing today. But the pattern of discoveries offers one of the earliest public clues about where Apple Car Key support may be headed before any official announcement.

What Apple Car Key support GWM Tank code actually shows

Backend code references suggest integration work may be underway, not that a launch is imminent. The Lucid and Xiaomi identifiers appeared in iOS 27 beta code, which signals closer proximity to a potential release. The Tank reference appeared at a less visible layer: Wallet backend infrastructure. Because it surfaced there rather than in a shipping beta build, it provides a less direct public signal than identifiers found in a live iOS beta.

None of the code, across any of these discoveries, specifies which models will be supported, which markets would be eligible, or when any rollout might happen.

The broader context makes that gap between signal and availability less surprising. Apple named 13 brands at WWDC 2025 as gaining Car Key support "soon," a list that included Lucid, Porsche, Rivian, Acura, and four Chinese automakers, among others, without attaching a public timeline to most of those commitments, per MacRumors. As of this week, Lucid has yet to formally confirm when the feature will arrive on its Air or Gravity models, despite being on that list for over a year, MacRumors reported.

In Lucid's case, Apple named the brand before identifiers appeared in beta code. The Tank reference is an earlier and less specific signal because neither Apple nor GWM has announced supported models or timing.

For current Tank owners: what this discovery does and doesn't change

Support depends on each vehicle's hardware and software implementation, so the code does not establish whether existing Tank vehicles could become compatible. Apple introduced digital car keys with iOS 14 in 2020, and manufacturers like BMW, Rivian, Kia, and Hyundai have implemented support since then, according to MacRumors. In those rollouts, support has generally depended on vehicle hardware rather than a software update pushed to existing cars, which means a backend code reference says nothing about whether current models on the road would benefit, or only future production vehicles.

When Car Keys in Apple Wallet arrives on a supported vehicle, the baseline capability works like a physical key: lock, unlock, start, via iPhone or Apple Watch held near the vehicle's NFC reader. Some manufacturers build in additional capabilities on top of that floor. Passive entry through newer wireless protocols is one option; key-sharing with another user is another. Those capabilities vary by vehicle implementation and may require compatible vehicle hardware and Apple devices.

The available code provides no clarity on which Tank models might qualify, whether any rollout would be China-only or extend to markets where Tank sells internationally, or whether software could eventually extend support to vehicles already on the road, MacRumors reported. Those answers come from GWM, not from Apple's backend.

Why Chinese brands keep appearing in these signals

GWM-owned Wey was already among the 13 brands Apple named at WWDC 2025; Tank now appears likely to follow within the same corporate family, MacObserver reported. Count up this month's code sightings alongside last year's WWDC list, and Chinese brands Wey, Hongqi, Chery, Voyah, Xiaomi, and now Tank account for a significant portion of the expanding partner set. That concentration reflects active regional work, not coincidence.

Xiaomi's presence in the iOS 27 beta is worth pausing on. The company is a direct Apple competitor in smartphones, yet its EV division which expanded into cars with the SU7 sedan and YU7 SUV appears to be moving toward Apple Wallet integration anyway, MacRumors reported. Car key support would mark one of Xiaomi's first ecosystem tie-ins with Apple despite the rivalry on the handset side. The EV division, it seems, is running a different calculation entirely.

Some of the regional groundwork has been accumulating for years. The Car Connectivity Consortium's China Market Task Group whose meetings have included representatives from Xiaomi, Continental, BMW, and Ingeek has been advancing the Digital Key standard across the region, the CCC noted in August 2023. Shared infrastructure alignment across manufacturers makes parallel Apple Wallet integrations technically easier to execute. That context helps explain why multiple Chinese brands can be moving in the same direction simultaneously, though the CCC work and Apple's Wallet integrations are separate tracks.

What to watch before treating this as confirmed

Two signals are worth tracking before drawing conclusions about Car Keys in Apple Wallet for GWM Tank vehicles.

The first is Apple's CarPlay model availability page, where confirmed Car Keys-compatible vehicles are listed. Tank does not appear on that page, per MacRumors. When it does, that is the authoritative confirmation not a backend string or a beta identifier.

The second is a formal announcement from GWM naming specific Tank models, model years, and eligible markets. That kind of specificity is what backend code cannot provide. The Lucid example illustrates the gap: named by Apple over a year ago, still without a confirmed launch date as of this week.

Until GWM names supported models and Apple adds them to its compatibility list, Tank owners have a clue, not a launch. The backend reference suggests GWM is working toward integration a meaningful early signal, and right now the only one available.
