GM Digital Key for Cadillac, Tahoe, Suburban and Yukon: supported models and phones
GM is rolling out Digital Key with UWB and Bluetooth for selected 2025–2027 Cadillac, Chevrolet and GMC models, with sharing for up to seven additional devices.
Up to seven additional devices can receive a copy of a GM vehicle key through Messages, AirDrop, WhatsApp and other apps. GM has begun the production rollout of Digital Key: the virtual key is stored in Apple Wallet, Google Wallet or Samsung Wallet and can unlock and start the vehicle, operate the liftgate and precondition the cabin.
The first wave runs from September through mid-October. The official list is broader than many reports suggest: the feature is intended for the 2025–2027 Cadillac LYRIQ, 2026–2027 OPTIQ and 2027 VISTIQ. The 2026 VISTIQ is not currently listed. In December, support is due to expand to the 2026–2027 Chevrolet Tahoe and Suburban, the GMC Yukon and Yukon XL from the same model years, plus the 2027 Cadillac Escalade, Escalade IQ/IQL and CELESTIQ.
The system relies on UWB and Bluetooth. Ultra-wideband lets the vehicle determine the phone’s position more precisely, so it can unlock automatically as the owner approaches and lock again after they walk away. Setup requires the GM app, a physical key fob inside the vehicle and an active OnStar connection. GM lists iPhone 11 and newer, Apple Watch Series 6 and newer, and selected Google Pixel and Samsung Galaxy phones with UWB among compatible devices.
This is no longer an experimental feature. Earlier Cadillac support materials limited key sharing to three recipients, while the current official rollout allows up to seven additional devices. The owner can manage access to shared keys, and if a phone is lost or stolen the key can be removed from the wallet or disabled through OnStar.
GM is also overhauling its in-car software. On the Escalade IQ, the focus has shifted beyond sheer display size toward cameras, climate functions and driver profiles, while the latest Silverado and Sierra have received a new interface that more tightly integrates vehicle controls and smartphones. Digital Key follows the same logic: the phone becomes part of the vehicle experience without replacing the car’s own software platform.
For vehicles imported into markets where GM does not officially offer the feature, phone compatibility alone is not enough. Digital Key must be enabled for the specific model year and VIN, and initial setup requires the GM app and acceptance of OnStar terms. Buyers should therefore verify the function on the actual vehicle before relying on it.
