- Auto-Lock Function: The lock can be programmed to automatically re-lock after a set period (e.g., 30 seconds) after being unlocked. This feature enhances security.
- Passage Mode: This mode allows the door to remain unlocked for continuous access. To activate/deactivate, refer to the programming instructions in your detailed guide.
- Emergency Egress: The interior lever handle is always free for exit, regardless of the lock's status. This is a safety feature allowing quick escape in emergencies.

5. Maintenance

- Cleaning: Clean the lock surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish.
- Exterior Unit Design: The exterior unit of the SmartCode 10 is sealed and includes a drip hole at the bottom to allow moisture to escape. Do not obstruct this hole.
- Lubrication: Periodically lubricate the key cylinder with a graphite-based lubricant if key operation becomes stiff. Do not use oil-based lubricants.
6. Troubleshooting
If you encounter issues with your Weiser locks, refer to the following common troubleshooting tips:
- Lock Not Responding (SmartCode 10): Check the 9V battery. If the battery is low or depleted, replace it.
- Exterior Handle Moves But Does Not Unlock (SmartCode 10): This is normal behavior when the lock is engaged. The handle is designed to move freely without engaging the bolt when locked. Ensure a valid user code is entered or the key is used to unlock.
- Auto-Lock Delay Adjustment: The SmartCode 10 auto-lock delay can be set up to a maximum of 99 seconds. If you are unable to achieve this setting, ensure you are following the programming instructions precisely. The auto-lock feature cannot be completely disabled.
- Key Cannot Be Removed (SmartCode 10/Fairfax Knob): For keyed entry, the key must be returned to the fully locked or unlocked position before it can be removed from the cylinder.
- Interior Handle Not Engaging Bolt: The interior handle of the SmartCode 10 is designed to always engage the bolt for emergency egress, regardless of the lock's status. This is a safety feature.
- Loose Handle/Lever: Ensure all mounting screws are securely fastened. If a set screw is loose, tighten it carefully. If a specialized set screw is required, contact Weiser customer support for assistance.
- Difficulty Re-keying: Ensure you are using the correct SmartKey tool and following the re-keying instructions precisely.
