To update the master code on your TurboLock YL-6996-SS Keyless Lock, enhancing your security, follow these steps: First, input the existing master code (either the default '0123' or your current one). Then, press the '#' button. Wait until the beeping ceases, but the blue backlight remains illuminated. Next, enter your new master code, ensuring it begins with '0'. Finally, press the '*' key. The lock will confirm the successful update with two beeps. Remember, should you misplace or forget your master code, a hard reset is available to restore factory settings. For detailed instructions on performing a hard reset, consult Section 7 of the TurboLock YL-6996-SS Keyless Smart Lock User Manual. The manual provides comprehensive guidance and helpful illustrations to assist you.
