What to know before buying

Listing details to confirm

The standard St model is described as lacking built-in Wi-Fi, while the listing also names Wi-Fi connectivity and remote unlocking. Remote internet access and supported voice control require a compatible Sifely Wi-Fi Gateway sold separately. The lock-type field includes biometric, but the product details explicitly say there is no fingerprint reader, so do not expect fingerprint entry. Check the exact selected model and gateway bundle before purchase. The listing states standard US door fit dimensions, which should be compared with the existing door before installation.

Customer feedback highlights ease of installation, convenience, appearance and on-the-go locking or unlocking. Experiences with unlocking and Wi-Fi connectivity are mixed, and fingerprint recognition feedback is also mixed. That fingerprint concern should be read in context: the detailed listing says this St model has no fingerprint reader, so buyers should not treat those reports as confirmation of a St feature. Positive feedback about remote access also does not remove the listed need for a separately sold gateway for internet control.

Positive themes

Mixed feedback

Feedback about unlocking is mixed.
Fingerprint-recognition feedback is mixed, though the detailed St feature description says this model has no fingerprint reader.
Wi-Fi connectivity experiences are mixed.

Frequently asked questions

Can the Sifely St be controlled remotely over the internet?

The standard model is described as having no built-in Wi-Fi. Remote locking, unlocking and supported voice features require a compatible Sifely Wi-Fi Gateway, sold separately.

Does this lock have fingerprint recognition?

The product details explicitly state that it does not include a fingerprint reader. Although the lock-type field lists biometric, that conflicts with the detailed feature description, so fingerprint entry should not be assumed.

What entry methods are listed?

The listing describes keypad PIN, compatible key card, RFID key fob, Sifely app over Bluetooth and a backup physical key.

Will it fit my door?

The stated fit is for compatible US doors 1-3/8 to 2-3/16 inches thick, with a 2-1/8-inch bore and 2-3/8- or 2-3/4-inch backset. Measure the existing door before ordering.
