How can we help?
Open a question below to find practical guidance for your smart lock.
What warranty and technical support does YRHAND provide?
For eligible product quality issues that are not caused by misuse, accidental damage, or other human factors, we can provide replacement parts for self-installation when appropriate. Join the YRHAND Community to receive an additional 1-year warranty extension, giving you up to 2 years of warranty coverage in total. We also provide lifetime technical support.
Where will my order ship from?
YRHAND operates overseas warehouses in Saudi Arabia, the United States, France, Brazil, Russia, and Spain. Orders are dispatched from the nearest available warehouse based on current stock availability. If a product is unavailable locally, it may be shipped from another warehouse or from China.
Which YRHAND smart lock is right for my door?
Check your door type, thickness, opening direction, and mortise dimensions before ordering. If you are unsure, send photos and measurements to our support team and we will help confirm compatibility.
Can I install the smart lock myself?
Yes. Most customers can complete installation with basic tools by following the included manual and our video guides. Professional installation is recommended if the door requires drilling or mortise modification.
Does the lock work with Tuya or TTLock?
App compatibility depends on the version purchased. Please check the product title and specifications for Tuya or TTLock before ordering, as the two app versions are not interchangeable.
Does remote unlocking require a gateway?
Some Bluetooth versions require a compatible gateway for remote control outside Bluetooth range. Wi-Fi-enabled versions may connect directly. Refer to your product specifications for the exact connection method.
How do I add fingerprints, passwords, or cards?
Complete the initial administrator setup first, then add users and access methods through the lock menu or its compatible app. The exact steps are shown in the manual and video guide for your model.
What happens if the batteries run out?
The lock provides a low-battery warning in advance. If the batteries are fully depleted, use the emergency power port with a power bank, then unlock normally and replace the batteries.
Can I still use a mechanical key?
Yes. YRHAND smart locks include a mechanical key for emergency access. Keep at least one key in a secure location outside the locked property.
Are YRHAND smart locks suitable for outdoor doors?
Outdoor suitability varies by model. Choose a weather-resistant model and avoid continuous direct exposure to heavy rain or extreme conditions unless the product specifications explicitly support it.
What should I do if the fingerprint is not recognized?
Clean and dry the sensor and your finger, then try again with the finger placed flat. Register the same finger more than once from slightly different angles to improve recognition.
How can I get technical or after-sales support?
Contact YRHAND with your order number, product model, and a clear description or video of the issue. Our support team will help with setup, troubleshooting, replacement parts, and warranty questions.
