Sliding doors need a different kind of lock to a standard hinged front door, so if you're shopping for sliding door smart locks, the first thing to check is the lock's profile width and mortice size - not just its unlock features. Here's what actually matters when choosing a smart lock built for a sliding door frame.
Why Sliding Doors Need a Different Kind of Smart Lock
Sliding doors, especially aluminium and glass sliding doors common in Australian homes, have narrower frames and different handle mechanisms than a hinged door. A standard smart deadbolt designed for a timber front door often won't physically fit. Sliding door smart locks are built with a slimmer profile - our range includes options as narrow as 33mm - designed specifically to integrate with a sliding handle and track system.
Key Things to Check Before Choosing a Sliding Door Smart Lock
- Frame width and profile - slim and super slim options exist for narrower aluminium frames
- Mortice and backset size - needs to match your existing lock body or replacement mortice hardware
- Handle style - sliding handles are designed to sit flush and operate smoothly within the track
- Glass vs framed doors - confirm your door type before ordering, as compatibility varies
If you're unsure of any of these measurements, our team can review photos and dimensions of your door before you buy - it's a quick way to avoid ordering the wrong size mortice or plate.
Unlock Methods to Consider for Sliding Doors
Sliding door smart locks support the same range of unlock methods as standard smart locks - fingerprint, PIN code, RFID card and app control - plus a mechanical key override. Many models also support an optional Wi-Fi gateway for remote access and Amazon Alexa or Google Home integration, so you can lock and check your sliding door status from your phone.
Our Recommended Sliding Door Smart Lock Range
