Troubleshooting Guide
- Reset the smart lock.
- Unlock the door directly using the emergency mechanical key.
- Connect an external 5V power source via the Type-C USB port to power on the lock.
- Unlock the door using the physical backup mechanical key.
- Access the system menu bar to adjust system settings and alert volume as needed.
- Ensure standard high-quality alkaline batteries are installed.
- Check that the lock is aligned and installed properly. Verify if the bolt moves smoothly via the manual toggle switch; if friction exists, disassemble and reinstall the lock.
- Inspect internal components for any moisture or water ingress, as liquid exposure accelerates power drainage.

Frequently Asked Questions (FAQ)
Q1 How can I unlock the door if the batteries completely run out?
In case of power failure, you can plug a standard 5V power bank into the external Type-C emergency port to power the lock instantly, or unlock the door directly using the physical backup Grade C mechanical key.
Q2 How many users and credentials can this smart lock store?
The lock supports up to 100 fingerprint users, 100 numeric passcode sets, and 100 IC card sets, making it suitable for both private residences and rental properties.
Q3 What door thickness is supported for installation?
This smart door lock is compatible with doors with a thickness between 35mm and 50mm, fitting standard deadbolt configurations.
Q4 Can I monitor access records and control the lock remotely?
Yes, via the Tuya App integration. You can review 24/7 unlock history, receive instant security notifications, issue temporary access codes, and perform remote unlocking when paired with an IoT gateway.
Q5 How long does the battery last, and is there an alert before it dies?
With 4 standard AA batteries, the lock provides approximately 8 to 10 months of standard operation (around 5,000 door openings). A low-voltage warning alarm will trigger whenever the battery power drops to ≤4.8V.
Q6 How does the anti-peep sequential code feature work?
The anti-peep feature allows users to enter random numbers before and after their actual passcode. As long as the real password sequence is entered continuously without interruption, the lock will open, preventing bystanders from guessing your code.
