Two questions, about a minute. Keep a tape measure handy.

Where is this lock going?
This is a door lock. For a gate, our SL-G1 has a 34 mm panel made for narrow gate uprights and fingerprint readers on both sides.
Measure from the faceplate of your existing mortise to the centre of the square spindle hole. What does it read?
60 mm backset, 85 mm centres. This is the one most Australian doors take.
45 mm backset, 85 mm centres.
If your door slides, order the 3585 hook bolt version instead — a straight bolt will not hold on a slider.
If your door slides, order the 2885 hook bolt version instead.
A straight bolt has nothing to grip on a sliding door. Measure your backset, then order the hook bolt version of that size — 2885 hook or 3585 hook.
Measure from the faceplate to the centre of the square spindle hole. The sizing guide shows it with a diagram.

Guides and installation
Three numbers decide whether this lever goes on your door: the backset, the door thickness and the stile width. All three are on the drawing. Measure them first, then pick the latch or centres option that matches — the number in the option name is the measurement, not a style.

No published weather rating. The manufacturer does not state an IP rating for this lock. Fit it to an internal door, or to an entry door that sits under an eave, a porch or a roof. If your door takes direct rain, order the SL-G1 instead — it is rated IP66.
Remote unlocking is not included. Bluetooth only out of the box. The G2 gateway is what adds Wi-Fi, remote access and voice control, and it is bought separately.
Measure before you order, not after. The wrong backset is the single most common reason a smart lock will not go on. Two minutes with a tape measure saves a return.
Batteries. Check the packing list for whether cells are included; budget for a set of alkaline AAs either way.
This is not an Australian-certified product line yet. The manufacturer holds CE and FCC marks, which are European and American. Ask us before ordering if you need Australian compliance paperwork for a rental, a strata building or a commercial fit-out.
Before you buy
Fitting and measurement questions in depth live in the sizing guide. How to choose between our five types is in the buying guide.
If your door is hinged, between 35 mm and 55 mm thick, has a 60 mm or 70 mm backset and a stile at least 96 mm wide, yes. Those four numbers are the whole test.
It is the distance from the edge of the door to the centre of the round hole the handle sits in. Open the door, measure across the flat face, and you have it. The diagram above shows exactly where.
Not on its own — Bluetooth only reaches a few metres. Add the G2 gateway and you can, from anywhere.
No. This lock runs on TTLock, which supports Alexa and Google Assistant through the gateway. There is no Apple Home or Matter support.
Two things save you: the mechanical key, and the USB-C port on the outside of the lock. Touch a phone power bank to it and the keypad wakes up.
Most people can. If your existing hole is already 60 mm backset and 50–54 mm across, it is largely a swap. If you are cutting a fresh hole, or the latch mortise needs adjusting, a locksmith will do it quickly.
