Others | Cut the 86mm spindle to the desired length |
Step 2: Installing on an old door - Removing the Existing Euro Cylinder
If your door already has a Euro cylinder, remove it by unscrewing the side fixing screw. To assist with removing the cylinder, you might find it useful to insert a key and turn it slightly, while pushing/pulling the cylinder. This will provide a better grip, making it easier to remove the old cylinder out.

If your door has a pre-installed mortice for a Euro cylinder, skip the step above and proceed with inserting the provided cylinder into the slot. You may need to trim the cylinder tail to match your door’s thickness.
Warning:
Before trimming, ensure you leave 25-35mm of the tail protruding beyond the door level to ensure a proper fit in the motor slot. Remember, your door’s thickness will add to this measurement. Cutting it too short may disengage the manual knob turner, preventing manual operation.
Step 3: Attaching the Rubber Gasket to Back Plate
Place the rubber gasket over the plate to ensure a secure fit and prevent slipping. This also helps protect the door surface and improves stability.

Step 4: Securing the Back Plate
Place the cylinder spacer over the cylinder, then align the plate and secure it using the two screws. Ensure it is firmly attached for a stable fit.

Step 5: Mounting the Back Plate
Place the motor panel onto the plate, ensuring proper alignment, and secure it with the three screws. Tighten firmly for a stable installation.

Step 6: Inserting the Batteries
Ensure the batteries are fully charged before inserting them. Once in place, attach the battery cover to complete the installation.

Step 7: Testing mortice operation
Test the manual knob turner to ensure smooth rotation. Then, press the button underneath the lock to check if it locks and unlocks the door smoothly.

Step 8: Adding the door sensors
Adding the door sensors enables the lock to synchronise so that it waits to Auto-Lock (relock) until the door is closed again.

MF-Sensor on its own
Sensor positioning
On the edge of the inside of the door frame

MF-Sensor Position 1
Aligned so the bottom of the sensor is in line with the top of the Simpled logo on the lock

MF-Sensor Position 2
Just peel off the film from the adhesive pad and firmly stick to the edge of the inside of the door frame. When the door shut this will now trigger re-locking.
This sensor is preprogrammed into the lock and does not need to be added as a separated door sensor option in the app.
Congratulations! Your Simpled MF Lock is now installed and ready to use. You can now proceed with pairing it with your phone.
If supplied as part of a bundle you may also have the OA - Fingerprint/Keypad device

1. Open the Settings menu on the locks dashboard.
2. Tap on Wi-Fi.
3. Select Configure Network.
4. Choose a Wi-Fi network from the list.
5. Enter the network password and confirm.
Tip
Note: Only 2.4GHz networks are supported. 5GHz networks are not compatible.




2. Wi-Fi Sleep Mode (Power Saving Mode)
Wi-Fi Sleep Mode allows you to control how often the lock stays connected to Wi-Fi, helping to manage battery life based on your usage.
•When Sleep Mode is OFF
The Wi-Fi connection remains active at all times. This ensures you can access full remote features such as unlocking and real-time management.
However, this setting significantly increases battery consumption and is recommended only if constant remote access is essential.
•When Sleep Mode is ON
The lock will disconnect from Wi-Fi according to the schedule you’ve set, helping preserve battery life. This is ideal if you don’t need 24/7 remote access and prefer to wake or sync the lock only when required.
When Sleep mode toggled on for the first time, by default, it is set to be active all day, every day. This means the lock will stay disconnected from Wi-Fi at all times, unless you manually adjust this time frame.
Custom Wi-Fi Wake-Up Schedule
If you’d like your lock to stay connected during certain hours — for example, in the morning or evening — you can reduce the sleep period by editing the schedule. This allows you to create short windows when the lock wakes up, connects to Wi-Fi, and syncs with your app.
Tip
Use Cases:
•Enable Sleep Mode overnight to conserve battery.
•Schedule the lock to connect to the internet once or twice a day – for example, in the morning and evening – to ensure any new access codes or settings are properly synced.
Waking the Lock in Sleep Mode
When the lock is in Sleep Mode (offline), pressing any button on the keypad will wake it up. The lock will then attempt to connect to the configured Wi-Fi network to sync data or process any pending updates.
Note: Connection time may vary depending on your Wi-Fi signal strength.
App Status Display
Once the lock wakes and connects:
The app will show the lock as “Online”, and this status will remain visible for approximately 10 minutes.
In reality, the lock stays connected for only a few seconds to complete the sync, then returns to sleep mode (offline).
Tip
Please be aware that the “Online” status in the app may not immediately reflect the actual state of the lock. It can take up to 10 minutes for the status to update back to “Offline”.
Enabling Remote Unlock
To enable the remote unlocking feature:
1. Go to Settings.
2. Tap on Remote Unlock.
3. Toggle the switch to ON.

Add a remote controller:
This lock supports unlocking with a remote controller. Before using the remote, it needs to be added first. You need to perform the adding process while you are near the lock. The validity period of the remote can be set, it can be permanent or timed.

new timed/ permanent admin to
have the same level of access to
the lock.

even your guest will be able to add
new users and even register their
own fingerprint on the smart lock,
up to the time their users are valid.

FAQ:
1. Why can’t I open the door after the passage mode is enabled?
You need to unlock the door with any method for the passage mode to take effect.
What is the purpose of Auto Lock?
The auto-lock is a safety feature to relock the door a set number of second after you have unlocked it. The period is preset to five seconds but can be changed to any length you want in: Lock -> Settings -> Auto Lock.
Why do the batteries run down more rapidly than expected?
*It may be due to:*1. Standby power consumption keeping the bluetooth available over time
2. Occasionally heavy rain onto a fingerprint sensor can create lock activations which shorten the battery life
3. A short circuit (but this is much less likely)
