The McGrath NX1 is a lever smart lock for homes, with a larger body that covers the holes left by an old lock. It opens by fingerprint, PIN code, RFID card or tag, the McGrath Smart Locks app, or a backup key. It uses Bluetooth, and remote access needs a McGrath gateway. It suits hinged doors 35 to 54 mm thick and is best on a sheltered door. Locksmiths Perth 24/7 supplies and fits it anywhere in Perth, Western Australia.

Who the NX1 suits
The NX1 is a good swap for an older front door. When you take off a key lock, there are usually screw holes and a cut out left behind. The NX1 body is big enough to cover most of that, so the door looks tidy without patching.
It suits a family home where everyone wants to stop carrying keys. Adults use a fingerprint, younger kids get a code or a tag, and you can send a timed eKey to the cleaner from your phone.
What we check before we fit it
- Door thickness. It suits doors from 35 to 54 mm. If your door is thicker, the NX6 takes doors up to 110 mm.
- Latch or mortice. The NX1 comes as a tubular latch version or a European mortice version. We look at what your door has now and tell you which one fits with the least work.
- The old holes. The outside body is 234 by 76 mm. We measure your old lock and tell you what will be covered and what won’t.
- Weather. The outside is rated IP65, which is fine under a porch or verandah. A door that takes full sun and rain needs a talk first.
- The door itself. A dropped door or a rubbing latch flattens batteries faster, so we check it shuts cleanly.
Living with the NX1
- Batteries. 4 AA batteries. The lock beeps and the app warns you when they get low.
- Flat batteries. Use the USB C port with a power bank, or the backup key.
- Passage mode. Leaves it unlocked until you turn it off, handy for a party or a delivery day.
- Codes. Add extra numbers around your code so it can’t be read over your shoulder. Five wrong tries locks the keypad out.
- Reset button. You can switch it off in the app.
- Handing. We can set it for a left or right hand door on site.
NX1 or NX5?
They open the same ways and run on the same batteries. The NX1 takes doors from 35 mm and has a wider body, 234 by 76 mm. The McGrath NX5 starts at 38 mm doors and has a longer, narrower body, 255 by 65 mm. Which one hides your old holes better depends on the lock you have now, so we measure and tell you. For a door thicker than 54 mm, look at the McGrath NX6.

Common questions
Will the McGrath NX1 cover the holes from my old lock?

No. It connects to your phone by Bluetooth when you are near it. For remote access you need a McGrath gateway.

What if the NX1 batteries go flat?
