4. Maintenance
4.1 Battery Replacement
The Lockly Secure Plus operates on 4 AA alkaline batteries (included). Battery life typically lasts for several months. The Lockly App will notify you when battery levels are low. To replace batteries, follow the instructions in your installation guide to access the battery compartment on the interior assembly.
4.2 Rekeying
The lock is rekey-ready, meaning you can replace the key cylinder without needing to change the entire lock assembly. This can be done with a standard rekey kit by a qualified locksmith or by following specific instructions from Lockly support.
4.3 Cleaning
To clean the lock's exterior, use a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the satin nickel finish or the digital keypad. Ensure the keypad and fingerprint sensor are free of dirt or smudges for optimal performance.
5. Troubleshooting
- Lock Not Responding:
Check the battery level. Replace batteries if low. Ensure the lock is properly installed and all cables are securely connected.
- Fingerprint Sensor Not Working:
Ensure your finger is clean and dry. Try re-registering your fingerprint through the Lockly App. Clean the sensor surface with a soft cloth.
- Keypad Issues:
Ensure the keypad surface is clean. If numbers are not appearing or responding, check battery levels. If you are locked out, use the physical backup key or the override code provided on the card that came with your lock.
- App Connectivity Problems:
Ensure Bluetooth is enabled on your smartphone. If using the Wi-Fi hub, ensure it is powered on and connected to your home network. Restart the app or your phone if issues persist.
- Lockout Situation:
Always keep your physical backup keys in a safe, accessible location outside the property. The override code card is crucial for resetting the system if you are locked out and cannot use other methods.
