Installation Process
Begin by verifying door compatibility, then meticulously install the lock body, adjusting the latch and backset for a secure fit. Finally, attach the interior and exterior assemblies.
Step 1: Checking Door Compatibility
Before initiating the installation of your Kucacci Smart Door Lock, ensuring your door’s compatibility is paramount for a seamless and secure setup. Begin by accurately measuring your door’s backset – the distance from the door’s edge to the center of the borehole. This measurement dictates the corresponding latch length required for proper functionality.
Kucacci smart locks generally accommodate standard backsets, but verifying this dimension prevents potential installation issues. Next, confirm the door’s thickness falls within the lock’s specified range, typically between 1 3/8 inches and 2 1/4 inches. Doors outside this range may necessitate additional components or may not be compatible.
Inspect the door frame for sufficient structural integrity to support the lock’s installation. A weakened or damaged frame could compromise security. Finally, ensure the existing deadbolt hole is appropriately sized and aligned for the Kucacci lock mechanism. Careful pre-installation assessment guarantees a trouble-free and robust security solution.

Step 2: Installing the Lock Body
With door compatibility confirmed, proceed to install the Kucacci Smart Lock body. Begin by removing your existing deadbolt lockset, carefully disconnecting all linkages and screws; Insert the Kucacci lock body into the door borehole, ensuring the latch bolt extends and retracts smoothly.
Align the lock body with the pre-drilled holes and secure it using the provided mounting screws. Tighten these screws firmly, but avoid over-tightening, which could damage the door or lock mechanism. Pay close attention to the orientation of the lock body, ensuring it aligns correctly with the exterior and interior assemblies.
Double-check that the latch bolt operates freely and engages properly with the strike plate on the door frame. If necessary, adjust the latch position to ensure a secure and reliable lock. A properly installed lock body forms the foundation for the entire smart lock system, guaranteeing optimal performance and security.
Step 3: Adjusting the Latch and Backset
Precise latch and backset adjustment is crucial for seamless Kucacci Smart Lock operation. Measure your door backset, then adjust to the corresponding latch length. The backset refers to the distance from the door edge to the center of the bore hole. Kucacci locks typically accommodate standard backsets, but adjustments may be needed.
Locate the adjustment mechanism on the latch bolt. Use a screwdriver to modify the latch’s position, ensuring it aligns perfectly with the strike plate on the door frame. Proper alignment prevents binding and ensures smooth locking and unlocking. Test the latch repeatedly to confirm its functionality.
Tighten the screw after adjusting the handle direction and complete this step. Incorrect backset or latch alignment can lead to operational issues and reduced security. Take your time and verify each adjustment for optimal performance and a secure fit.
Step 4: Installing the Interior and Exterior Assemblies
With the latch and backset correctly adjusted, proceed to install the interior and exterior lock assemblies. Carefully align the exterior assembly with the mortise and ensure the connecting cable passes through the designated opening. Secure the exterior assembly using the provided screws, tightening them firmly but avoiding over-tightening, which could damage the components.
Next, install the interior assembly, connecting it to the exterior assembly according to the instructions. Ensure all cables are securely connected to prevent malfunctions. Once connected, test the lock’s basic functionality – manually lock and unlock it using the interior thumbturn.
Verify that the handle operates smoothly and that the lock engages and disengages correctly. Long press KUCACCI for 2 seconds to manually lock from outside to test this function. A secure and proper installation of both assemblies is vital for the lock’s overall performance and security.

Troubleshooting and Maintenance
Address issues like low battery alerts, connectivity problems, and keypad malfunctions. The Kucacci app displays remaining power, aiding in timely battery replacement and optimal lock performance.
Low Battery Alerts and Replacement
Your Kucacci smart lock is designed to provide ample warning when the batteries are running low. Expect to receive notifications both within the Kucacci app, indicated by a power alert logo on the main screen, and potentially audible alerts from the lock itself. These alerts are crucial for preventing unexpected lock failures.
When the low battery warning appears, it’s time to replace the batteries promptly. The lock typically requires batteries (specific type to be detailed in the ‘Parts List’ section of this manual). Ensure you use high-quality batteries for optimal performance and longevity. To replace them, locate the battery compartment (refer to the ‘Installation Process’ section for its location).
Carefully remove the old batteries and insert the new ones, paying close attention to the polarity (+ and -) markings. Once the new batteries are installed, the lock should automatically power on and reconnect to the app. Verify the connection within the app to confirm successful battery replacement. It’s recommended to keep a spare set of batteries readily available to avoid any inconvenience.
Resolving Connectivity Issues
If your Kucacci smart lock experiences connectivity problems, several troubleshooting steps can be taken. First, ensure your smartphone or tablet has a stable internet connection – either Wi-Fi or cellular data. Verify the lock is within range of your home’s Wi-Fi network. If the signal is weak, consider relocating your Wi-Fi router or using a Wi-Fi extender.
Next, check the Kucacci app to confirm it’s running the latest version. Outdated app versions can sometimes cause compatibility issues. Within the app, attempt to re-pair the lock with your smartphone. If this fails, try restarting both the lock (by briefly removing and reinserting the batteries) and the Kucacci app.
If problems persist, consult the app’s ‘Help’ section or the Kucacci website for further assistance. There you may find specific troubleshooting guides or FAQs addressing common connectivity issues. As a last resort, consider resetting the lock to its factory settings (refer to the ‘Advanced Settings’ section for instructions), but be aware this will erase all saved user data and require re-setup.
Addressing Keypad Malfunctions
If the Kucacci smart lock’s keypad becomes unresponsive or exhibits erratic behavior, begin with a simple battery check. Low battery power can often lead to keypad malfunctions. Replace the batteries with fresh ones, ensuring correct polarity. If the issue persists after a battery replacement, try cleaning the keypad surface with a soft, dry cloth to remove any dirt or debris that might be interfering with the touch sensors.
Next, attempt a soft reset of the lock by briefly removing and reinserting the batteries. This can sometimes resolve minor software glitches. If the keypad remains faulty, consult the Kucacci app for diagnostic information. The app may display error codes or provide troubleshooting suggestions.
As a more drastic measure, consider resetting the lock to its factory settings. However, be aware that this will erase all saved user codes and require you to re-enter them. Refer to the ‘Advanced Settings’ section for detailed instructions on performing a factory reset. If none of these steps resolve the problem, contact Kucacci customer support for further assistance.
Checking Remaining Power in the App

The Kucacci app provides a convenient way to monitor the remaining battery life of your smart lock. Upon opening the app and navigating to the lock’s device page, you’ll find a dedicated section displaying the current battery percentage. This feature allows for proactive battery replacement, preventing unexpected lockouts due to depleted power.
The app will also show a corresponding remaining power alert logo when the battery level drops below a critical threshold.

Regularly checking the battery status within the app is recommended, especially during periods of frequent lock usage.
Pay attention to any low battery warnings received through the app’s notification system. These alerts are designed to provide ample warning before the lock ceases to function. Ensure that you have spare batteries readily available to avoid inconvenience. Consistent monitoring via the app ensures your Kucacci smart lock remains reliably operational.

Adjusting Handle Direction
Ensuring proper handle orientation is crucial for seamless Kucacci smart lock operation. If the handle doesn’t align with your door’s existing setup, adjustment is necessary. Begin by locating the adjustment screw, typically found on the interior assembly near the handle base.
Using a suitable screwdriver, carefully loosen the screw – do not fully remove it. Gently rotate the handle to the desired direction. Once aligned correctly, firmly tighten the adjustment screw to secure the new position. Remember to measure your door backset and adjust to the corresponding latch length before finalizing this step.
After adjusting the handle direction, double-check its stability and smooth operation. Ensure the handle moves freely without resistance and that it securely engages the latch mechanism.
