Install the Laser Smart Internal Door Lock with Fingerprint only after checking that the door is compatible: 35mm to 55mm thick, 60mm or 70mm backset, 54mm cross-bore and a single-cylinder lock configuration.

1. Charge the lock first. Use a USB-C cable and 5V USB power source. A full charge from empty takes up to 3.5 hours. The charging cable and power source are not included.

2. Remove the existing lock and its components.

3. Fit the supplied latch. For a 60mm backset use the latch as supplied. For a 70mm backset pull the rear of the latch to extend it. Insert and secure the latch with mounting screws.

4. Fit the strike box and strike plate. You may retain the existing strike plate if the bolt moves smoothly. Adjust its position if the door must be pushed or pulled for smooth operation.

5. Place the exterior fingerprint knob against the outside of the door, passing its spindle through the latch assembly.

6. Remove the interior knob from its mounting plate using the supplied unlocking pin. Point the mounting plate's UP arrow upwards, align it with the exterior connectors and secure it using the supplied mounting bolts.

7. Tighten the mounting bolts by hand only. Do not use a power drill.

8. Align the interior knob's thumb latch with the spindle, then push the knob onto the mounting plate.

9. Connect the lock to the Connect SmartHome app and register authorised fingerprints straight after installation.

IMPORTANT: Before the initial app setup and fingerprint registration, the lock accepts any fingerprint. Complete setup immediately; once configured it will reject unregistered fingerprints.

Refer to the illustrated installation pages in the user manual when positioning the components. Consider professional installation if you are unsure of the door or lock configuration.
