Frequently Asked Questions
Q: Does the Asia-Teco LD03 Tuya fingerprint lock work without a Wi-Fi connection?
A: Yes. The LD03 connects via Bluetooth, so you can unlock it directly from the Tuya Smart Life app on your phone without a Wi-Fi connection. For remote access (when you're away from home), a Tuya-compatible gateway is required to connect the lock to your Wi-Fi network.
Q: What door thickness is this smart lock compatible with?
A: The Asia-Teco LD03 is designed for doors between 30 mm and 55 mm thick and fits most standard wooden and sliding doors. It is compatible with single latch 60/70 and a wide range of European mortise sizes, covering approximately 99% of standard residential doors.
Q: What happens if the batteries die — will I be locked out?
A: No. The lock features a backup USB external power port on the front panel. Simply connect a USB power bank to temporarily power the lock and gain entry. You can then replace the internal dry cell batteries from inside without any lockout risk.
Q: How many fingerprints and passcodes can the lock store?
A: The LD03 supports multiple user fingerprints and passcodes for the whole household. Exact capacity is detailed in the included manual. The Tuya Smart Life app also allows you to manage, add, or delete access credentials remotely at any time.
Q: Is this lock suitable for outdoor or exterior doors?
A: The LD03 features a waterproof rubber design that provides a degree of weather resistance, making it suitable for exterior-facing wooden doors. However, please note the product specifications list it as not fully waterproof (IP-rated), so it is best used in covered or sheltered doorways rather than in direct heavy rain exposure.
