Smart access for homes and rentals

The Sifely S Fingerprint Smart Lock combines a heavy-duty deadbolt knob with biometric, code, app, FOB and mechanical-key entry. It suits homeowners, families, short-term rental hosts and small offices that want keyless convenience without a Wi-Fi bridge.

Battery-powered operation with voice alerts

Four AA cells run the lock and the Bluetooth radio; a power bank can provide emergency power if the batteries run flat. The built-in speaker announces low-battery warnings, successful unlocks and failed attempts so you hear the status without checking a phone.

Fits standard doors and works with Alexa via gateway

The 1.2 in x 3 in x 7 in trim installs with a screwdriver on typical residential doors. Pair the optional Sifely Gateway to enable Amazon Alexa and Google Assistant voice control, and use the app to create temporary codes for guests or cleaners.

Questions about this item

How is the Sifely S smart lock installed on a front door?

The lock is designed for DIY installation on standard doors. The step people often get wrong is aligning the deadbolt knob and latch assembly so the bolt throws smoothly without binding.

What maintenance will the Sifely S lock need over time?

The lock runs on AA batteries. You will need to replace them periodically; a low-battery alert sounds on the device and appears in the app. If batteries die completely, a power bank can temporarily power the lock via the external contacts.

How fast does the fingerprint sensor unlock the Sifely S lock?

The biometric sensor recognises a registered fingerprint in 0.3 seconds, which is the first performance limit you notice during repeated daily use.
