Frequently Asked Questions
Q: Does the YRHAND K01 Bluetooth smart lock require professional installation?
A: No — the K01 is designed as a direct drop-in replacement for standard cylindrical (round knob) door locks. No drilling or special tools are required. It fits doors 35–55 mm thick and works on both left- and right-hand doors, making DIY installation quick and straightforward.
Q: What happens if the batteries run out?
A: The lock features a built-in USB Type-C emergency power port (5 V / 2 A). Simply connect a power bank or USB charger to the port to temporarily power the lock and use your app or mechanical key to gain entry. The low-battery alarm will alert you well in advance so you can replace the 4 × AAA batteries before they are fully depleted.
Q: Can I use this smart lock without a smartphone?
A: Yes. The K01 supports both biometric fingerprint unlocking (up to 20 stored fingerprints) and traditional mechanical keys, so you can always access your door even without a phone. The Tuya / Smart Life app adds remote and app-based control as a convenient extra option.
Q: Is the YRHAND K01 suitable for outdoor doors?
A: The lock carries an IP66 protection rating, meaning it is fully dust-tight and withstood powerful water jets in testing. It also operates across a wide temperature range of -20°C to +50°C, making it well-suited for exterior residential doors in a variety of climates.
