SwitchBot Lock Ultra (silver) is a smart door lock designed for European doors that combines fast recognition, multiple unlocking methods and Matter-compatible smart home integration. The lock opens in about 0.3 seconds with 98% recognition accuracy, uses Bluetooth 5.2 and Fast Mode for quick response, and features a silent motor with improved speed. The compact aluminum housing and included wood-texture overlays allow a discreet fit with interior finishes.
Advantages
The lock provides near-instant access and quiet operation, with an automatic Night (Quiet) Mode that reduces noise below 20 dB and disables sound effects. It supports a wide range of European locking mechanisms (Deadbolt, Jimmy Proof and Mortise with adapter), offers multiple unlocking options including fingerprint, NFC, smartwatch, voice and auto-unlock, and lets you create permanent, one-time, temporary and masked passcodes. Power redundancy includes a main rechargeable battery, a frost-resistant CR123A backup cell and emergency USB‑C power, ensuring continued operation for up to nine months under typical use. Full Matter and major smart home platform support enables centralized access control and automation when used with a SwitchBot hub.
