4.3 Compatibility

Easy Fit is compatible with many Scandinavian and European thumbturn locks.

Before installation:

• Verify that the thumbturn operates smoothly.
• Ensure the lock can be locked and unlocked without excessive force.
• Confirm sufficient space around the thumbturn.
• Check that the door lock is suitable for indoor residential use.

Do not install the product on doors where lock operation requires excessive force.

The lock is intended for indoor residential use only.

Keep batteries away from children.

Do not expose the device to water, excessive humidity, or extreme temperatures.

Do not mix battery brands or battery types.

6.1 Before Installation

1. Install the Heimgard Door App.
2. Enable Bluetooth on your smartphone.
3. Ensure the door is unlocked and open.
4. Verify lock compatibility.

6.2 Select the correct mounting components

This section explains how to select the correct mounting components for your installation. While every installation requires a mounting plate and a thumbturn clamp, some installations may also require optional components to ensure a secure fit and reliable operation.

Additional components may be required if:

• The existing door lock plate or escutcheon creates a gap between the mounting plate and the door.
• The thumbturn or key protrudes too far from the door and additional clearance is required.
• The thumbturn stem requires additional grip for a secure fit.

If the Smart Lock sits securely, the thumbturn or key is firmly engaged, and the lock operates smoothly, you can proceed with the installation without using any optional spacers.

Before installing the Easy Fit Smart Lock, take a moment to identify the mounting components that best fit your existing door lock. Selecting the correct combination of mounting plate, clamp, spacer and rubber insert ensures smooth operation and reliable performance.

Mounting Plate

The mounting plate is secured to your door and provides the base for attaching the Smart Lock.

Ensure the mounting plate is centred correctly before securing it in place. Incorrect alignment may affect the lock's operation and calibration.

Selecting the Correct Clamp

The Easy Fit Smart Lock includes two thumbturn clamps to accommodate different thumbturn designs and stem lengths.

• Clamp A (24 mm) is pre-installed in the Smart Lock and is suitable for most installations.
• Clamp B (32 mm) is included in the box and should be used when the existing thumbturn stem requires a longer clamp.

If Clamp A does not fully engage the thumbturn or cannot securely hold it, replace it with Clamp B.

After selecting the appropriate clamp, verify that:

• The thumbturn is held firmly.
• The clamp fully engages the thumbturn stem.
• The thumbturn rotates freely without binding.
• There is minimal side-to-side movement.

If the thumbturn stem is too narrow to fit securely in either clamp, install the rubber insert before mounting the lock.

Using the Rubber Insert

The rubber insert is designed for thumbturn stems that are narrower than the clamp opening.

Install the rubber insert inside the selected clamp before mounting the Smart Lock.

The insert should be used whenever additional grip is needed to eliminate movement between the thumbturn and the clamp.

When the Smart Lock is installed over a key cylinder, Heimgard also recommends using the rubber insert whenever possible. This provides a more secure grip on the key head and helps ensure reliable operation.

Do not force the rubber insert into the clamp if the thumbturn or key already fits securely without it.

Selecting the Correct Mounting Spacer

The Easy Fit Smart Lock includes two 3 mm and one 10 mm spacers that are installed behind the mounting plate.

Use a spacer whenever there is a gap between the mounting plate and the door surface or escutcheon. The spacer fills this gap, allowing the mounting plate to sit firmly and level before the Smart Lock is installed.

Select the combination of spacers that provides the best fit. The supplied spacers can be stacked using the included adhesive pads to achieve additional thickness. For example:

• 3 mm spacer
• 10 mm spacer
• Two 3 mm spacers + one 10 mm spacer (approximately 17 mm total thickness, including the adhesive pads)

Choose the thinnest spacer combination that allows the mounting plate to:

• Sit flush against the door lock plate or escutcheon.
• Be securely fastened without rocking or bending.
• Remain level and properly aligned.

Once the mounting plate is securely installed, attach the Smart Lock and verify that the thumbturn rotates freely without resistance.

Using the Lock Body Spacer (Riser)

The Lock Body Spacer is used when the existing thumbturn or a key left in the cylinder protrudes too far from the door, preventing the Smart Lock body from sitting flush against the mounting plate.

Installed between the mounting plate and the Smart Lock body, the spacer acts as a riser, increasing the distance between them and providing additional clearance for taller thumbturns or keys.

Use the Lock Body Spacer if:

• The Smart Lock body cannot sit flush against the mounting plate because the thumbturn or key is too tall.
• The selected clamp cannot fully engage the thumbturn or key.
• Additional height is required for the Smart Lock to operate correctly.

Installing the Lock Body Spacer

1. Position one Lock Body Spacer on each side of the mounting plate, aligning the spacer holes with the mounting plate screw holes.
2. Using the longer screws supplied in the accessory bag, secure both spacers to the mounting plate. Tighten the screws until the spacers are firmly attached.
3. Position the Smart Lock body over the two installed spacers, aligning the screw holes on the lock body with the threaded holes in the spacers.
4. Secure the Smart Lock body to the spacers using the appropriate screws and tighten both sides evenly.

The Lock Body Spacer increases the distance between the mounting plate and the Smart Lock body, allowing the selected clamp to fully engage taller thumbturns or keys while ensuring the Smart Lock sits securely and operates correctly.

After installation, verify that:

• The Smart Lock body is firmly secured.
• The selected clamp fully engages the thumbturn or key.
• The thumbturn or key rotates freely without binding.
• The Smart Lock sits level and does not rock or move during operation.

Final Fit Check

Before tightening the mounting screws, confirm that:

• The lock body is correctly aligned.
• The thumbturn turns smoothly by hand.
• The lock fully locks and unlocks the door.
• There is no excessive resistance or rubbing.
• The original key can still be used normally, if applicable.

Only tighten the mounting screws once the Smart Lock operates smoothly during manual testing.

6.3 Installing the Smart Lock

Once you have selected the appropriate mounting components described in Section 6.2, you are ready to install the Smart Lock.

For illustrated installation guidance, follow the guided installation in the Heimgard Door App.

Installation Procedure

1. Ensure the door is open and unlocked throughout the installation.
2. Clean the mounting surface around the thumbturn or key cylinder using the supplied adhesive promoter wipe. Allow the surface to dry completely.
3. Attach the adhesive pad to the mounting plate and use the alignment guide to centre the mounting plate over the thumbturn or key. Firmly press the mounting plate into position before removing the alignment guide.
4. Open the battery cover by moving the battery cover switch to the O position and sliding the cover off.
5. Insert four AA batteries, observing the polarity markings. The Smart Lock will power on automatically.
6. If applicable, install the optional thumbturn cover plate.
7. Remove the Smart Lock knob and verify that the correct clamp has been selected. If required, install the rubber insert, mounting spacer, or Lock Body Spacer as described in Section 6.2.
8. Position the Smart Lock body onto the mounting plate, ensuring the thumbturn or key is fully engaged by the clamp.
9. Before tightening the mounting screws, confirm that:

• The Smart Lock body sits level and securely.
• The thumbturn or key rotates freely by hand.
• The internal mechanism operates smoothly without binding.

• Keep your smartphone within Bluetooth range of the Smart Lock and keypad.
• Ensure both devices remain powered on.
• Do not close the app until the pairing process has completed.

Once pairing is complete, the app will automatically continue to the calibration process.

7.3 Calibrate Your Smart Lock

After pairing your devices, the Heimgard Door App will guide you through the calibration process.

During calibration, the Smart Lock automatically determines the required thumbturn travel to operate your door lock and verifies that the deadbolt can move freely without excessive resistance.

When prompted by the app:

1. Close the door completely.
2. Ensure the Smart Lock is not obstructed.
3. Select Start Calibration.

The Smart Lock will automatically rotate the thumbturn several times while determining the required travel for locking and unlocking.

The calibration process typically takes 30-60 seconds.

7.4 Calibration Check

Once calibration is complete, the app will ask you to confirm how the lock performed during the calibration process.

Did the lock turn smoothly and fully lock the door?

• Select Yes, it turned smoothly if the lock completed its full movement without difficulty.
• Select No, it struggled to turn if the lock stopped before reaching the end position, required noticeable force, or did not complete its movement.

If you select No, it struggled to turn, the app will automatically enable Force Mode and repeat the calibration to optimize the Smart Lock for higher-resistance door locks.

After the calibration has been completed successfully, continue to verify the lock direction.

7.5 Verify Lock Direction

After the calibration check, the app will ask you to verify the lock direction.

Follow the on-screen instructions and test the door handle to determine whether the door is currently locked or unlocked.

Select the option that matches the actual state of your door. Based on your selection, the app will configure the correct lock direction for your Smart Lock.

Once the lock direction has been confirmed, the app will continue with the remaining setup steps.

7.6 Configure Spring Latch Mode

The final step of the setup process is to configure Spring Latch Mode.

Spring Latch Mode is designed for doors where the thumbturn must be held in the unlock position while opening the door. When the thumbturn is released, it automatically returns to its original position by spring action, allowing the door lock to relock automatically once the door is closed.

When prompted by the app, manually unlock the door and attempt to open it.

• Select Yes, it springs back if the thumbturn automatically returns to its original position when released. The app will enable Spring Latch Mode.
• Select No, it stays unlocked if the thumbturn remains in the unlocked position after being turned. The app will configure the Smart Lock for standard lock operation.

If you are unsure which option to choose, test the door manually before making your selection.

Spring Latch Mode can be enabled or disabled at any time from the Lock Settings in the Heimgard Door App.

7.7 Create Your First User

If a Heimgard Keypad has been paired with your Smart Lock, the app will prompt you to create your first user.

Enter a unique user name and create a 4-10 digit PIN code. This PIN can be used immediately to unlock your door using the keypad.

Additional users, PIN codes, Key Tags and fingerprints can be added or managed later from the Door Settings. Key Tags and fingerprint access are available on supported keypad models only.

Once your first user has been created, the initial setup is complete.
