5. Operation
The Sargent KP10G77 lock offers straightforward operation for secure access.
Accessing the Door:
- Keypad Entry: To unlock the door from the exterior, enter a valid user code on the keypad. The outside lever will then become active, allowing you to retract the latch bolt and open the door.
- Key Override: In case of power failure or if preferred, the lock can be opened from the exterior using the physical key provided. Insert the key into the keyhole on the lever and turn to retract the latch bolt.
- Interior Access: From the interior, the lever handle always retracts the latch bolt, allowing for immediate egress.
Passage Mode:
If configured, the lock may have a passage mode where the outside lever remains active without requiring a code. Consult your programming instructions for details on enabling or disabling this feature.
Horn Activation:
The lock includes a feature where a horn can be activated when keypad buttons are pushed. This can be a useful audible indicator. Refer to your programming instructions for how to enable or disable this feature.
6. Maintenance
Regular maintenance helps ensure the longevity and smooth operation of your Sargent KP10G77 lock.
- Cleaning: Clean the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically, a small amount of graphite lubricant can be applied to the key cylinder to maintain smooth key operation. Do not use oil-based lubricants as they can attract dirt.
- Fastener Check: Periodically check all mounting screws and fasteners to ensure they are tight. Loose fasteners can affect the lock's security and operation.
7. Troubleshooting
If you encounter issues with your Sargent KP10G77 lock, consider the following common troubleshooting steps:
- Keypad Not Responding: Ensure the keypad is clean and free from debris. If the lock is battery-powered (though this model is not explicitly stated as such, some keypad locks are), check battery levels.
- Code Not Working: Verify that the correct code is being entered. Ensure no buttons are stuck. Re-enter the code slowly and deliberately. If issues persist, try reprogramming the code according to the programming instructions.
- Lever Not Retracting Latch: Check for any obstructions in the door frame or latch bolt. Ensure the lock is properly installed and aligned. If the outside lever is rigid, confirm a valid code was entered or the key was used correctly.
- Key Not Working: Ensure the correct key is being used and that the key cylinder is free of debris. Apply graphite lubricant if the key feels stiff.
For persistent issues, it is recommended to consult a qualified locksmith or contact Sargent customer support.
