Manual & installation
The manual covers door measurements, included parts, installation, initial setup and app operation. Use the download button in the viewer to save a copy.
- Check that the model on your lock or packaging is HK01W before using these instructions.
- Follow the door-measurement diagrams and installation sequence in the manual. If you are unsure about your door, contact us before modifying it.
- Keep the door open while checking the lock and your chosen unlocking methods. Keep the physical key accessible outside the locked property.
App setup & Apple Home
LNDU app
Use the LNDU app QR code in the HK01W manual to find the correct app. The manual identifies the LNDU app for the lock's full function settings.
To enter app pairing mode, briefly press the interior SET button and wait for the pairing voice prompt, then add the lock in the LNDU app. Do not hold SET unless you intend to restore factory settings.
Apple Home & Home Key
Follow the Apple Home section of the manual: use the interior HomeKit button and setup code to add the lock in Apple Home, then complete Home Key setup. Keep the setup code private.
Apple Home remote control and automations require a compatible Apple home hub. This is separate from using Home Key at the door or the LNDU app's connection.
Battery & backup access
- The manual illustrates an 8-AA battery installation. Use batteries of the same age and condition; do not mix old and new batteries.
- Replace the batteries promptly when the low-battery warning appears.
- A physical key provides an alternative way to unlock. Store it somewhere accessible when you are outside.
- The external emergency power port supplies temporary power only; it does not recharge the batteries. Follow the manual before using it.
Before resetting or requesting help
For an app issue, tell us whether you are using LNDU or Apple Home and share the exact error message. For a lock that sticks or does not respond, tell us whether it happens with the door open, closed, or both.
A factory reset removes settings. Do not reset as a first troubleshooting step if you need to preserve access settings; contact support for guidance.
