Frequently asked questions
How do I unlock the door?
How do I unlock the door?
Three ways — press your finger on the fingerprint sensor and the door opens in 0.2 seconds, unlock via the Bluetooth app on your phone, or use the physical key backup. All three work independently so you're never locked out.
Will it fit my existing door?
Will it fit my existing door?
Yes, if your door has a standard US ball knob. The Smart Knob fits backset sizes of 2-3/8" or 2-3/4" (60mm or 70mm) and works on both left and right-handed doors with no modifications needed.
Is it difficult to install?
Is it difficult to install?
No. It replaces your existing knob using the same screw holes — no drilling required. All you need is a standard screwdriver. Most customers are done in under 10 minutes.
Can multiple people have access?
Can multiple people have access?
Yes. You can register up to 50 fingerprints directly on the knob — enough for your whole household and regular visitors. Each fingerprint is stored and recognised independently.
Does the fingerprint work with wet or cold hands?
Does the fingerprint work with wet or cold hands?
The semiconductor sensor works reliably in most conditions. If your hands are heavily wet, a quick dry is recommended. Registering multiple fingers in different conditions improves first-touch accuracy.
Can I give a cleaner or guest access without sharing my fingerprint?
Can I give a cleaner or guest access without sharing my fingerprint?
Yes. Via the Bluetooth app you can create temporary access codes to share with guests, cleaners, or tradespeople. You'll need to be within Bluetooth range of the knob to set this up.
Can I lock or unlock it remotely from another location?
Can I lock or unlock it remotely from another location?
No. The Smart Knob uses Bluetooth, which means app control requires your phone to be within Bluetooth range of the knob. It does not support remote WiFi access.
Does it work with Alexa or Google Home?
Does it work with Alexa or Google Home?
No. The Smart Knob uses Bluetooth only and does not connect to smart home hubs or voice assistants.
Which app do I download?
Which app do I download?
Download the SmartLock app, available free on iOS and Android. The app lets you manage fingerprints, create temporary codes, and control the knob via Bluetooth.
How secure is it compared to a traditional knob?
How secure is it compared to a traditional knob?
More secure. There are no keys to copy or lose, and the fingerprint sensor has a false recognition rate of less than 0.001% — meaning it will not open for the wrong fingerprint.
How long does the battery last?
How long does the battery last?
Typically 6–12 months depending on usage. The app shows your battery level so you always know before it runs low. Physical key access works regardless of battery status.
