Samsung’s Wallet app is expanding its Digital Key feature, allowing Galaxy smartphone users to lock and unlock their vehicles directly from their phones. Since its 2021 debut, the digital key has grown from supporting a select few models to covering major brands such as BMW, Mini, Genesis, Kia, Hyundai, and Mercedes-Benz. The latest update adds Porsche to the Digital Key lineup, enabling Porsche owners to unlock their cars with a compatible Galaxy device. How it works: To use Digital Key, you’ll need a compatible Galaxy device with the Samsung Wallet app and a car that supports Digital Key. In a supported vehicle, you can add the key in Samsung Wallet and simply present your Galaxy phone near the car to unlock it, with the option to start the engine in many cases as well. Availability and features can vary by region, model, and phone hardware. Why it matters: A growing ecosystem of Digital Key-compatible vehicles means fewer keys to carry and faster, contactless access to your car. With Porsche now on board, more drivers can enjoy the convenience and security of unlocking and, in some cases, starting their car using just their Galaxy device. If you own a Porsche or are considering a digital key future, check Samsung’s official Digital Key compatibility page to confirm model support, region availability, and steps to set up the feature on your Galaxy device.
