4.1 Unlocking the Door
- Passcode Entry: Enter your 4-10 digit user passcode on the keypad, then press the 'Lock' button (or checkmark/enter button, depending on model). The lock will retract, allowing you to open the door. The lock supports up to 20 user passcodes.

4.3 Advanced Security Features
- Anti-Peeping Password: To prevent others from guessing your passcode, you can enter random digits before or after your correct passcode. The lock will still recognize the correct sequence within the longer string.
- Wrong Code Entry Limit: The lock will temporarily disable the keypad after multiple incorrect passcode attempts, preventing unauthorized access.
- Low Battery Alert: The lock will provide an audible or visual alert when the batteries are running low, prompting you to replace them before the lock loses power.
- Mute Mode: For quiet operation, the keypad sounds can be silenced.
- Vacation Mode: A special mode that disables all user codes for enhanced security when you are away for an extended period.

5. Maintenance
Proper maintenance ensures the longevity and reliable operation of your YOSIMIKA Keyless Entry Door Lock.
- Battery Replacement: When the low battery alert activates, replace all four AA batteries promptly. Use high-quality alkaline batteries for best performance.
- Cleaning: Clean the keypad and lock body with a soft, dry cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and electronic components.
- Environmental Protection: While the lock has an IP54 waterproof rating, protecting it from prolonged direct exposure to extreme weather conditions (heavy rain, snow, direct sunlight) can extend its lifespan.
6. Troubleshooting
If you encounter issues with your YOSIMIKA Keyless Entry Door Lock, please refer to the following common solutions:
- Lock not responding to keypad: Check if the batteries are dead or low. Replace them if necessary. Ensure the keypad is clean and free of debris.
- Lock not locking/unlocking: Verify that the deadbolt is not obstructed by the door frame. Check if the door is properly aligned. Re-enter the passcode carefully.
- Passcode not working: Double-check the passcode. Ensure you are not in vacation mode. Try resetting the lock to factory settings and reprogramming the passcodes (refer to the specific instructions in your quick start guide for reset procedures).
- Low battery alert persists after battery change: Ensure new batteries are inserted correctly with the correct polarity.
- Keypad backlight not working: Check battery level. If the issue persists, contact customer support.
