1. Check door lock compatibility.

Your existing lock should be a single-cylinder deadbolt and meet the requirements of the following dimensions. You can use the provided template to measure your door.

2. Remove your existing door lock and bolt.

3. Install the new bolt.

1) Ensure the word TOP is facing up.

2) If the backset of your door is 2-3/8’’ (60 mm), install the bolt directly.

If the backset of your door is 2-3/4’’ (70 mm), rotate the bolt to extend it before installation.

3) Insert the bolt into the door hole and use two mounting screws to affix it. The bolt mounting screws are packaged together with the bolt.

4. Install the exterior assembly.

1) Place the exterior assembly sticker on the door’s exterior side by aligning its door edge line with the door’s edge. Ensure you use the correct door edge line based on your backset distance.

2) Route the cable under the bolt.

3) Insert the tailpiece and two prongs into the corresponding holes on the bolt and align the exterior assembly with the sticker.

5. Install the mounting plate.

1) Place the interior assembly sticker on the door’s interior side by aligning its door edge line with the door’s edge. Ensure you use the correct door edge line based on your backset distance.

2) Route the cable through the mounting plate’s rectangular hole and insert the tailpiece into the center round hole. Align the mounting plate with the sticker, ensuring the two prongs of the exterior assembly match the two holes next to the center round hole. Secure it with the screws.

6. Install the interior assembly.

1) Remove the battery cover.

2) Connect the cable tightly. Ensure the color side faces up.

3) Align the tailpiece with the key cylinder. Attach the interior assembly to the mounting plate.

4) Rotate the thumb latch to ensure the latch retracts normally.

5) Use the three provided M4*7.5 screws to affix the interior assembly. The provided ST4×20 screw is optional. It is used to secure the interior assembly.

7. Install the batteries.

1) Insert the battery into the interior assembly. Replace the battery cover.

2) Insert the silicone cover into the bottom hole. Remove the stickers.

8. Install the strike plate.

Insert the dust box and strike plate into the strike hole on the door frame. Ensure the depth of the strike hole is at least 1’’ (25.4 mm).

Note: If the bolt operates smoothly without pushing or pulling the door, you can use your original strike plate.

If you need to push or pull the door for smooth operation, adjust the strike plate's position on the door frame.

9. Installation is complete.

Set up your door lock and enjoy it. You can also charge the battery while the device is in use.
