1. Introduction
This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of your Veise KS02C Fingerprint Keyless Entry Door Lock. Please read this manual thoroughly before installation and use to ensure proper function and safety.
The Veise KS02C is a smart front handle set featuring a fingerprint keypad deadbolt combined with two knobs, offering multiple unlocking methods for enhanced security and convenience.
2. Safety Information
- Battery Safety: Use only 4 AA alkaline batteries. Do not mix old and new batteries, or different types of batteries. Replace all batteries at the same time. Remove batteries if the lock will not be used for an extended period.
- Environmental Conditions: The lock is rated IP54 waterproof, suitable for outdoor use. However, extreme weather conditions may affect performance. Ensure the fingerprint sensor is clean and dry for optimal recognition.
- Physical Security: While the lock is designed with an ANSI Grade 3 sturdy lock cylinder and alloy, it is important to ensure your door and frame are also secure.
- Code Security: Avoid sharing your master code. When entering codes, utilize the anti-peeping feature by entering random digits before or after your actual code.
- Fingerprint Management: Be cautious when adding or deleting fingerprints. Deleting a fingerprint requires the registered finger to be scanned. If a user is no longer available, a factory reset may be necessary to remove their fingerprint access.

7. Troubleshooting
- Lock Not Responding: Check battery levels. Replace batteries if low. Ensure the cable connection between the exterior and interior assemblies is secure.
- Fingerprint Not Recognized: Ensure your finger is clean and dry. Try re-registering your fingerprint. If the issue persists, try a different finger or use a code/key.
- Keypad Not Responding: Check for low battery. If the keypad is backlit but not responding to input, try a factory reset (refer to programming guide).
- Cannot Delete Fingerprint: To delete a specific fingerprint, the registered finger must be scanned during the deletion process. If the person is unavailable, a factory reset of the lock may be required to clear all stored fingerprints and codes, after which you can reprogram new ones.
- Wrong Entry Limit: If incorrect codes are entered 10 times, the lock will temporarily disable for 3 minutes as a security measure. Wait for the lockout period to expire before attempting entry again.
