Operating Instructions
Setting/Changing the Password
The process for setting or changing the password involves internal pins on the lock mechanism. Refer to the specific instructions in your included manual for detailed steps on how to configure your 1-11 digit non-repeating code.
Unlocking the Door
- Enter your programmed password by pressing the corresponding buttons on the keypad. The order of pressing the digits does not matter (e.g., if the code is '123Y', '123Y', '1Y23', 'Y321' will all work).
- Turn the knob to retract the deadbolt.
- Open the door.
Reset Function
If an incorrect password is entered, or if you wish to clear a partial entry, press the 'C' key. This will reset the keypad, allowing you to re-enter the correct password.

Maintenance
To ensure the longevity and optimal performance of your Ejoyous Mechanical Combination Lock, follow these maintenance guidelines:
- Cleaning: Wipe the lock's exterior with a soft, damp cloth. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the chrome-plated and electroplated finish.
- Lubrication: Periodically apply a small amount of graphite lubricant to the internal moving parts of the latch mechanism to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and grime.
- Screw Tightness: Periodically check all mounting screws and tighten them if necessary to prevent loosening over time.
- Environmental Protection: While the lock is designed to be durable, extreme weather conditions can affect its performance. Consider additional protection for outdoor installations in harsh environments.
