Samsung Electronics is making a significant push to turn its Galaxy smartphones into the only thing consumers need to carry when they leave the house. The South Korean tech giant has expanded Samsung Wallet’s capabilities to include digital keys for smart locks, a move that positions the company more aggressively against Apple in the race to replace physical wallets, car keys, and now house keys with a single mobile device.
The update, which began rolling out in recent weeks, allows Samsung Wallet users to store and use digital keys compatible with a growing list of smart lock manufacturers. According to Android Police, Samsung Wallet now supports digital keys for smart locks from several prominent brands, enabling Galaxy phone owners to tap their device against a compatible lock to gain entry — much the same way they would tap to pay at a retail terminal.
From Payment App to All-Purpose Digital Credential
Samsung Wallet has undergone a dramatic transformation since its origins as Samsung Pay, the company’s mobile payments service. Over the past two years, Samsung has aggressively broadened the application’s scope, folding in boarding passes, digital IDs, car keys, and student credentials. The addition of smart lock support represents the latest step in Samsung’s strategy to make the wallet app indispensable to the daily routines of its massive global user base, which numbers in the hundreds of millions of active Galaxy device owners.
The smart lock integration works through NFC (Near Field Communication) technology, the same short-range wireless standard that powers contactless payments. When a user approaches a compatible smart lock, they can simply hold their Galaxy device near the lock to authenticate and unlock it. The digital key is stored securely within Samsung Wallet, and the company says the credentials are protected by the same Knox security platform that safeguards payment information and other sensitive data on Galaxy devices.
Which Smart Lock Brands Are Supported?
The initial rollout includes support for locks from several manufacturers that have adopted interoperable digital key standards. As reported by Android Police, Samsung has been working with smart lock partners to ensure broad compatibility, though the full list of supported devices continues to expand. Samsung has historically partnered with companies like Yale, Schlage, and other lock makers for its SmartThings platform, and the Wallet integration appears to build on those existing relationships while also opening the door — quite literally — to new partnerships.
The timing of this expansion is notable. The smart lock market has been growing steadily, with research firms projecting it will exceed $4 billion globally by 2027. Consumer adoption has accelerated as more homeowners invest in connected home devices, and the pandemic-era shift toward remote work has made home security technology a higher priority for many households. Samsung’s move to integrate smart lock access directly into its wallet app could accelerate adoption further by lowering the friction involved in managing digital keys.
The Competitive Landscape with Apple
Samsung’s expansion into digital keys for smart locks puts it in direct competition with Apple, which has offered home key support in Apple Wallet since 2021. Apple’s implementation works with HomeKit-compatible smart locks and uses NFC on iPhones and Apple Watches. However, Apple’s home key feature has been limited by the relatively small number of lock manufacturers that have adopted full HomeKit integration, with brands like Schlage and Aqara among the early supporters.
Samsung may have an advantage in sheer scale. Android devices account for roughly 72% of the global smartphone market, according to Statcounter data, and Samsung is the world’s largest smartphone manufacturer by unit shipments. By building smart lock support into Samsung Wallet, the company gives lock manufacturers access to a far larger potential user base than Apple can offer alone. This could incentivize more lock makers to adopt the digital key standards that Samsung supports, creating a virtuous cycle of expanding compatibility.
Security Considerations and Consumer Trust
Storing house keys on a smartphone raises obvious security questions that Samsung will need to address convincingly if it wants mainstream adoption. The company has pointed to its Knox security architecture as the foundation for protecting digital keys. Knox uses hardware-backed security, including a dedicated secure processor on Galaxy devices, to isolate sensitive credentials from the rest of the phone’s software. This means that even if a device is compromised by malware, the digital keys stored in the secure enclave should remain protected.
There is also the practical concern of what happens when a phone’s battery dies. Samsung Wallet supports a power reserve mode on newer Galaxy devices, which allows NFC functions — including payments and digital keys — to continue working for a limited time even after the phone has shut down due to low battery. This addresses one of the most common objections consumers raise about relying on a phone for access to their home. Still, the feature is only available on select newer Galaxy models, which means older device owners may not have the same safety net.
The Broader Trend Toward Digital Credentials
Samsung’s smart lock integration is part of a much larger industry trend toward digitizing physical credentials of all kinds. Governments around the world are experimenting with digital driver’s licenses and national ID cards that can be stored on smartphones. Airlines have largely moved to digital boarding passes. Car manufacturers including BMW, Hyundai, and Genesis now support digital car keys that can be shared between phone users without ever exchanging a physical fob.
The Connectivity Standards Alliance, the industry group behind the Matter smart home protocol, has also been working on standards for digital keys and access credentials. The organization’s efforts to create interoperable standards could eventually allow a single digital key protocol to work across Samsung Wallet, Apple Wallet, Google Wallet, and other platforms. Such standardization would be a significant development for consumers who live in multi-platform households where family members use different phone brands.
What This Means for the Smart Home Industry
For smart lock manufacturers, Samsung Wallet support represents a major new distribution channel. Rather than requiring consumers to download a dedicated app for each lock brand — a pain point that has long plagued the smart home industry — manufacturers can now allow users to store and manage their keys within an app that is already pre-installed on every Galaxy phone. This reduces setup friction and could drive higher engagement with smart lock features.
The integration also strengthens Samsung’s position in the broader connected home market, where it competes with Amazon, Google, and Apple. Samsung’s SmartThings platform already serves as a hub for controlling a wide range of smart home devices, and the addition of smart lock keys to Samsung Wallet creates a tighter connection between the company’s mobile and home platforms. A consumer who uses a Galaxy phone to unlock their front door is more likely to invest in other Samsung-compatible smart home products, from security cameras to smart lighting.
Looking Ahead: What Samsung Needs to Get Right
The success of Samsung Wallet’s smart lock feature will depend on several factors in the coming months. First, the company needs to expand the list of compatible lock brands quickly enough to reach a critical mass of consumers. A feature that only works with one or two lock models will struggle to gain traction. Second, Samsung must ensure that the user experience is reliable and fast — if unlocking a door with a phone takes noticeably longer than using a physical key, consumers will revert to old habits.
Third, and perhaps most importantly, Samsung needs to build consumer confidence that storing house keys on a phone is safe. The company’s track record with Knox and mobile payments provides a strong foundation, but home access is a more emotionally charged category than tap-to-pay at a coffee shop. A single high-profile security incident could set back adoption significantly. For now, Samsung appears to be taking a measured approach, expanding the feature gradually while building out its partner network. If the company executes well, the day when most people leave home carrying nothing but their phone may arrive sooner than many expect.
