General Motors is joining the digital key revolution, beginning a rollout this fall that will allow drivers of select new vehicles to lock, unlock and drive their cars using their smartphones.
Cadillac EVs Get Digital Keys First
GM’s phased rollout begins between September and mid-October for eligible 2026 and 2027 Cadillac electric vehicles. The first models to receive the feature are the Lyriq, Optiq and Vistiq.
Backend software code spotted earlier this year suggested GM was preparing Apple digital keys for Cadillac, and the announced timeline confirms that development. The system allows drivers to walk up to their vehicle, drive away, securely share virtual keys with up to seven people through text and pre-condition cabin temperatures directly from their smartphones.
The technology uses ultra-wideband and Bluetooth connections to provide a hands-free experience. Drivers can manage the digital key through their devices instead of carrying a physical key.
Digital Keys Expand to Chevrolet and GMC
GM plans to expand the digital key functionality beyond Cadillac by December. The rollout will include the 2026 and 2027 Chevrolet Tahoe and Suburban, along with the GMC Yukon and Yukon XL.
Flagship models including the Escalade IQ and the bespoke Celestiq will also receive the update before the new year.
How GM’s Digital Key Technology Works
The digital key system is based on the Car Connectivity Consortium standard, with data encrypted within the secure elements of the user’s smartphone.
The virtual key can be stored in Apple Wallet, Google Wallet or Samsung Wallet alongside payment cards. Compatible ultra-wideband devices include recent iPhones, Google Pixel phones and Samsung Galaxy models.
Initial setup is handled through GM’s OnStar-connected mobile application, allowing drivers to configure the digital key on their compatible device.
Digital Keys Arrive as GM Changes Smartphone Integration
The addition of digital access comes as GM works to remain competitive in the automotive market, where German rivals have used similar wallet technology for several years. The rollout begins with Cadillac before expanding to high-volume models such as the Chevrolet Tahoe.
At the same time, GM has eliminated smartphone mirroring integration in favor of its proprietary Google-based infotainment system, a move that has frustrated some customers.
That means drivers can use an iPhone Wallet app to securely unlock a new Cadillac Lyriq while still being unable to project their favorite iOS navigation apps onto its dashboard, highlighting the contrast between GM’s adoption of smartphone-based digital keys and its approach to smartphone mirroring.
