For a Galaxy household, Samsung Wallet is the reason to put a lock in SmartThings. Its Digital Home Key is added during SmartThings Matter setup and opens the door with an NFC tap, or hands-free over UWB where phone and lock support it. Availability depends on region and lock model: the
ULTRALOQ Latch 5 Pro and Aqara U400 have the tap today, while Aqara's Samsung UWB unlock was still in development in August 2026. Almost every lock here uses Thread, so plan on a SmartThings hub with Thread. Code handling varies by brand: Kwikset and Yale list code management in SmartThings, while fingerprint enrollment, as on the
ULTRALOQ Bolt Fingerprint, stays in the maker's app.
