• Ensure you have a PH1 standard Phillips screwdriver available for installation.
• For optimal installation results, we recommend following along with our installation video.

Installation Methods

EU Mortise Lock

If Your Door Has an Interior Key

Ensure the key thickness is ≤5mm and the key handle length is ≤39mm when inserted into the lock. Confirm that you can still unlock the door from the outside with the key when the interior key is inserted. If the existing lock cylinder doesn't meet these requirements, it may cause serious issues. Please replace it with a compatible one before installation.

[Diagram: Illustrates a door lock cylinder with a key inserted from the inside and the exterior handle. Dimensions indicate a maximum interior key thickness of 5mm and a maximum exterior handle length of 39mm.]

If Your Door Has an Interior Dial

Remove the dial or handle screws and select the appropriate adapter based on the shape of the lock cylinder tailpiece. If the dial cannot be removed from the existing lock cylinder, replace the lock cylinder before installation.

[Diagram: Shows a set of five lock cylinder adapters, each with different shapes on its ends, designed to fit various lock cylinder tailpieces.]

Measure the thickness of the interior door lock cover and the height of the lock cylinder protruding from the cover.

You may choose to use the included EVA pad to enhance stability. Adjust the thickness by stacking the EVA pads as needed. The difference between the thickness of the stacked EVA pad and lock's exterior cylinder should be guaranteed to be within ±1mm.

[Diagram: Shows a cross-section of a door with the lock installed. It illustrates measuring the interior door cover thickness (A) and the protruding lock cylinder height (B), with the requirement A-B < ±1mm. It also shows stacking EVA pads to adjust thickness.]

Screw Installation

If the lock cylinder protrudes ≥3mm, you can secure the fixed plate using screws. Use the provided hex key to tighten the three screws clockwise to secure the lock to the cylinder. Over-tightening may affect the lock cylinder's performance, causing issues with locking and unlocking.

Note: After removing the fixed plate, pre-tighten the screws by turning them 10 times clockwise to speed up the installation process.

3M Adhesive Installation

If the lock cylinder protrudes ≤3mm, you can use the 3M adhesive method to secure the fixed plate, or replace the lock cylinder before installation. The difference between the thickness of the stacked EVA pad and lock's external cylinder should be within ±1mm.

Clean the area around the fixed plate and cylinder to remove dust. Peel off the yellow backing of the 3M adhesive and apply it to the fixed plate. Then peel off the red backing and attach it to the lock cylinder. Press and hold the fixed plate for 60 seconds to enhance adhesive's strength. To remove the fixed plate, use a hairdryer to heat the adhesive, making it easier to detach.

Installing the Key or Adapter

Note: Adapters are consumable parts and may need replacement after about 2 years. You can purchase new adapters or download 3D files from the Aqara website to print your own. Aqara cannot guarantee the strength and durability of self-printed adapters.

Open the battery cover and secure the lock to the fixed plate with screws. Rotate the knob to ensure smooth locking and unlocking. Adjust the screw tightness if necessary to avoid operational issues.

Lock Calibration

After installation, users can calibrate the door lock using the Aqara Home app or directly on the lock. Here's how to calibrate on the lock:

1. Close the door and unlock it from the inside. Press and hold the Set button on the lock for 3 seconds to start calibration.
2. The lock will beep twice, then rotate to the unlock and lock positions. It will play a tune when the calibration is complete.

Note: Two beeps during calibration indicate failure. The lock won't function properly if calibration is incomplete. If calibration fails or there is a calibration issue, check if the mounting screws are too loose or tight and adjust them before retrying.

Notion: If calibration issues persist, use the manual/automatic calibration feature in the Aqara Home app.
