Auslock S2B-D Slim Double-Sided Smart Lock

Secure both sides. Control every entry.
The world-class solution for homes, Airbnb, medical, commercial + child safety.
Unlike standard smart locks that only secure the outside, the S2B-D locks BOTH sides of your door — the inside and the outside require authorisation.
This means:
  • Kids cannot open the door from inside
  • Guests can't exit restricted areas without permission
  • Staff cannot escape security zones
  • Intruders cannot leave once inside
🛡️ The safest way to secure a property is to secure the exit as well.

🔥 Why Customers Love the S2B-D

  • Double-Sided Verification — each panel works independently
  • Premium SS304 Stainless Steel — commercial-grade durability
  • Zero Wi-Fi hacks — Bluetooth offline locking
  • Smart App Control — full user management
  • Mechanical + Powerbank Backup — never get locked out
  • Airbnb & Commercial Ready — send digital access instantly

If the gate is a new gate then you can refer the slim series product to the gate fabricator who can have the gate fabricated in accordance to the slim series dimensions to ensure a perfect fit.

Does the cost include installation?

No, a separate charge shall apply for installation service that you can book through Aus Smart Locks or one of our approved dealers.    

Can this lock work on sliding doors?

Can I Change My Smart Lock’s Master Password?

Is it possible to open the door lock if the battery runs out?

Yes, you can open the door lock in two ways – you can charge up the door lock using a power bank with android cable. Then, you can use your card, fingerprint or password to open the door. Another way is to use the manual override key provided.

Does the slim series work with the multi locking system?

Yes, the slim series retro fits onto the existing multi locking system, which means that you will not need to use our own mortice. It will also make the installation part easier, requiring less effort.
