Smart Lock Buying Guide Australia
Choosing a smart lock starts with the door, not the app. This guide helps Australian buyers compare door fit, access methods, connectivity, weather exposure, power and emergency access before selecting a model.
Step 1: Identify the Door
Record whether the door is timber, metal, aluminium, glass, a security screen, hinged or sliding. Measure the door thickness and available panel width. Photograph both faces, the edge, the strike and the existing lock. Narrow frames and sliding doors often require specialised hardware.
Step 2: Measure the Existing Lock
Measure the backset from the door edge to the centre of the handle or cylinder. If a mortice lock is fitted, record the faceplate size, body dimensions and pitch between the handle spindle and cylinder where relevant. Work in millimetres and do not estimate.
Step 3: Choose Access Methods
| Fingerprint | Fast daily access for regular users. |
|---|---|
| PIN code | Useful for family, guests and service providers. |
| Card or NFC | Practical for selected workplaces and shared users. |
| Face or palm recognition | Contactless access on premium models. |
| App | Administration, records and remote functions where supported. |
| Mechanical key | Important physical backup on models that include it. |
Step 4: Understand Connectivity
Direct Wi-Fi, Bluetooth and mesh locks behave differently. Direct Wi-Fi can provide internet connectivity without a separate gateway where supported. Bluetooth is efficient for nearby phone access, but remote functions may require a compatible gateway. Tuya and TTLock gateways are not interchangeable.
Step 5: Check Exposure and Materials
An exterior lock should suit the environmental exposure. Check the stated IP rating, materials and product limits. Coastal sites need particular attention to salt exposure, maintenance and the complete door hardware. SABER uses 304 stainless steel and is listed as IP68 for narrow-frame, sliding and security-screen applications.
Step 6: Plan Power and Backup
Identify the battery type, expected maintenance process, low-power warning and emergency power port. Keep any mechanical key outside the locked property in a secure location. Test emergency access after installation.
Step 7: Select by Application
- Main entrance: prioritise fit, reliable backup and everyday ease of use
- Internal room: choose a latch or deadbolt format that matches the door
- Airbnb: prioritise guest PINs, remote administration and a local backup plan
- Aluminium or sliding door: use a purpose-designed narrow-frame solution
- Cabinet or drawer: measure panel thickness and internal clearance
- Gate or toolbox: match padlock body, shackle and weather rating
Step 8: Install and Test
Accurate drilling and alignment are essential. The latch or bolts must move freely into the strike. Test every access method with the door open, then test repeated cycles with the door closed. Keep the installation template and manual.
Frequently Asked Questions
Can any smart lock replace my current lock?
No. Door thickness, backset, mortice, bore holes, handing and clearance must match or be modified correctly.
Is fingerprint or PIN better?
Fingerprint is quick for regular users, while PINs can be easier to issue to guests. Many locks provide both.
Do I need a gateway?
Only when the selected lock and desired remote function require one.
Are smart locks suitable for coastal homes?
Use a model and installation suited to coastal exposure, then maintain the complete door hardware. Check the stated material and environmental rating.
Should I use a professional installer?
Use an experienced installer when the door needs mortice work, new drilling, narrow-frame modification, wiring or security-door changes.
