The McGrath A231 is a narrow stile smart lock with a 31 mm wide body, so it fits on the thin frame of most swinging aluminium doors. It opens by fingerprint, PIN code, RFID card or tag, the McGrath app over Bluetooth, or a backup key. WiFi is not built in, so remote access needs a McGrath gateway. It suits doors 28 to 55 mm thick. Locksmiths Perth 24/7 supplies and fits it anywhere in Perth, Western Australia.

Who the A231 suits
The A231 is one of the slimmest locks McGrath makes. At 31 mm wide it sits on aluminium door frames where a standard smart lock would hang over the glass. That makes it a good fit for an aluminium front door, a back door off the patio or a small business entry.
It suits anyone who wants to stop cutting keys for everyone. Each person gets a code, card or fingerprint, and you can take one away without touching the others. Add a McGrath gateway if you want to manage it from your phone away from home.
What we check before we fit it
- Door thickness. It suits doors 28 to 55 mm thick.
- Frame width. We measure the stile so the 31 mm body sits square on it.
- The mortice. It comes with a European mortice and works with McGrath’s 85 series. We check the lock in the door now and tell you what changes.
- Handle choice. The A231 has a narrow lever. If you would rather a straight pull handle, or the door slides, we will show you the hex handle versions.
- Weather. IP65 on the outside handles rain under a verandah. We will say so if your door is too exposed.
Living with the A231
- Batteries. Four AAA. Low battery warnings come up in the app and the lock beeps.
- Flat batteries. Hold a power bank to the USB C port and enter your code, or use the key.
- Passage mode. Keeps the door unlocked for a busy day.
- Keeping codes private. Type extra digits around your code, and the keypad locks out after 5 wrong attempts.
- Entry log. The app records every opening.
- Left or right. Handing can be changed on site.
A231 or A231HEX?
Same 31 mm body and the same ways to open it. The A231 has a lever; the McGrath A231HEX has a straight hex handle and can go on swinging or sliding aluminium doors.
