- A45 B45: Recommended for door thickness from 70mm to 85mm.
- A50 B50: Recommended for door thickness from 70mm to 85mm (Circular type).
Important Note: The distance from the lock cylinder to the edge of the door is 21mm. Please confirm this measurement in your installation environment before purchasing.
4.2. Installation Steps
- Remove your existing lock cylinder using a hex screwdriver.
- Insert the new Zemismart Smart DoorLock cylinder into the mortise.
- Secure the lock cylinder in place.
- Test the mechanical key function to ensure proper operation.
5. Setup
5.1. Tuya App Setup
- Download the Tuya Smart or Smart Life App from your mobile app store.
- Register or log in to your account.
- Ensure your phone's Bluetooth is enabled.
- Open the app and follow the on-screen instructions to add a new device. The app should detect the lock via Bluetooth.
- Follow the prompts to pair the lock with your app.
Note: For remote control and access to unlock records from anywhere, a Tuya Bluetooth Gateway (hub) is required. Without the gateway, app control is limited to Bluetooth range.
5.2. Fingerprint Registration
The lock supports up to 100 fingerprints. Follow the instructions within the Tuya App to register new fingerprints. Typically, this involves placing your finger on the sensor multiple times from different angles until successfully registered.
5.3. IC Card Registration
The lock supports IC cards for unlocking. Use the Tuya App to add new IC cards. This usually involves scanning the card near the lock's card sensing area after initiating the registration process in the app.
6. Operation
The Zemismart Smart DoorLock offers four convenient ways to unlock your door:
- Fingerprint Unlock: Place your registered finger on the fingerprint sensor. The lock will recognize your fingerprint and unlock.
- IC Card Unlock: Tap your registered IC card on the card sensing area of the lock.
- Tuya App Unlock: Open the Tuya App on your smartphone and tap the unlock icon. If a BLE hub is connected, you can unlock remotely.
- Key Unlock: In case of emergency or preference, use the provided mechanical key to unlock the door. The keyhole is typically hidden under a cover on the lock.
6.1. Smart Housekeeper Features
When connected to the Tuya App and a BLE gateway, the lock provides smart notifications and alerts:
- User Member: Manage access for different users.
- Back Home Notifications: Receive alerts when family members arrive home.
- Alarm Alert: Get notifications for unusual activity or attempted breaches.
- Hijack Alarm: Activate a silent alarm or alert system if forced entry is detected or a specific 'hijack' fingerprint/password is used.
6.2. Remote Unlocking
With a Tuya BLE Gateway, you can remotely unlock your door from anywhere using the Tuya App. This allows you to grant access to visitors even when you are not home.
7. Maintenance
7.1. Battery Replacement
The lock is powered by one CR123A (Alkaline) battery. The device features a low battery alarm to notify you when the battery needs replacement. To replace the battery, locate the battery compartment (usually on the interior side of the lock) and insert a new CR123A battery, ensuring correct polarity.
7.2. Emergency Power
If the battery completely drains, you can use the 1x Micro Type-C charging port for emergency power. Connect a power bank or a Micro Type-C charger to temporarily power the lock and gain access.
7.3. Cleaning
Wipe the lock's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
8. Troubleshooting
- Fingerprint not working after several uses: Try re-registering your fingerprint in the Tuya App. Ensure your finger is clean and dry when using the sensor. If the issue persists, check the battery level.
- Battery charge not increasing above 10% after recharging: Verify that the Micro Type-C charging cable and power source are functioning correctly. The battery itself might be faulty and require replacement.
- Lock not found during app pairing: Ensure Bluetooth is enabled on your smartphone and the lock is within range. Try resetting the lock (refer to the app for specific reset procedures) and attempting pairing again. If using a BLE hub, ensure it is powered on and connected to your network.
- Remote unlocking not working: Confirm that you have a Tuya Bluetooth Gateway (hub) connected and configured correctly in the Tuya App. Ensure both the hub and your smartphone have internet access.
- Lock does not respond: Check the battery level. If the battery is dead, use the emergency Micro Type-C charging port or the mechanical key.
9. User Tips
- Multiple Fingerprints: The lock supports a large capacity of up to 100 fingerprints, allowing multiple users to have access.
- Remote Access: To unlock the door from outside your home, you will need to purchase and set up a Tuya Bluetooth Gateway (hub) in addition to the lock.
- Battery Life: While specific battery life varies with usage, the lock uses a standard CR123A alkaline battery and provides a low battery warning. It's advisable to keep a spare battery or a power bank with a Micro Type-C cable handy.
- Door Thickness Measurement: Before purchasing, carefully measure your door's thickness and the 'A' and 'B' dimensions of your existing lock cylinder to ensure you select the correct mortise lock size.
