Auslock S2B-D Slim Double-Sided Smart Lock
The Auslock S2B-D Slim Double-Sided Smart Lock is built for advanced access control, securing both sides of the door for added safety and peace of mind. Unlike standard smart locks, the S2B-D requires verification from both the inside and outside, making it ideal for homes, Airbnb properties, medical spaces, commercial sites, and child-safe environments. The front and back panels operate independently, with separate electronic structures and app setup for true double-sided security.
Designed for aluminium and wooden doors, the S2B-D supports multiple unlock methods including Bluetooth, fingerprint access on supported configurations, PIN code entry on the front panel, IC card access, mechanical key backup, and optional gateway connectivity. The front panel supports up to 200 fingerprints, 150 passwords, and 200 cards, while the back panel supports up to 200 fingerprints and 200 cards. It is made with SS304 stainless steel handle and panel materials, runs on 4 x AA batteries, and suits door thicknesses from 22–35 mm.
Through the Auslock app, users can manage Bluetooth unlocking, create and share permanent, timed, one-time, custom, recurring, and erase passcodes, send e-keys, add cards and fingerprints, and view unlock records. With the optional gateway, users can also remotely view records, calibrate the lock clock, and remotely delete or modify passwords.

integration with Alexa and Google Home, elevating home security and convenience.

Helpful Tips
- Lift the handle up to bring the deadbolt out
- Key goes behind the magnet cover which sits in front of the key hole.
- USB C Port is not a charger but a back up in case the batteries have gone flat and you cannot find your keys then you use the cable sourcing power from a power bank, plug into the lock then insert any of your registered features to get inside to change the batteries.
- After installing the lock please peel off the plastic film that is on the number touch pad otherwise over time the sun can melt it on the pad which will be problematic.
- If the auto lock feature is not active then you can lock the smart lock by holding # on the touch pad.
- Unlock Ways Back Panel: Card, Fingerprint, APP
