The Simplex Kaba LL1011-26D-41 lock operates using a mechanical push-button keypad and a lever handle.
4.1 Unlocking the Door:
- Enter the correct access code by pressing the corresponding buttons on the keypad in sequence.
- After entering the code, turn the lever handle to retract the latch and open the door.
- The lock will automatically re-lock once the lever is released and the door is closed.

The lock automatically engages when the door is closed. No manual action is required to lock the door from the exterior once the code has been entered and the door opened and closed.
4.3 Changing the Access Code:
The access code can be changed directly on the keypad without removing the lock from the door. This process typically involves a specific sequence of button presses and a programming key or tool. Refer to the separate programming instructions for your specific model for detailed steps on how to change the code.
It is recommended to change the access code periodically for enhanced security.
5. Maintenance
Proper maintenance ensures the longevity and reliable operation of your Simplex Kaba lock.
- Cleaning: Clean the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents, which can damage the finish.
- Lubrication: Periodically apply a small amount of graphite lubricant or a silicone-based spray to the latch bolt and internal mechanisms to ensure smooth operation. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly inspect the lock for any signs of wear, loose screws, or damage. Tighten any loose screws immediately.
- Keypad Buttons: Ensure all keypad buttons depress and release smoothly. If a button feels sticky or unresponsive, light lubrication may be applied.
