3. Install Outside Lever Assembly: Insert the outside lever assembly through the door, ensuring the spindle engages with the latch mechanism.
4. Install Inside Lever Assembly: Place the inside lever assembly over the spindle and secure it to the outside assembly using the through-bolts. Tighten screws evenly to prevent binding.

6. Test Operation: Before closing the door, test the latching mechanism and key operation from both sides. Ensure the lever operates smoothly and the key locks/unlocks the mechanism correctly.

• To Open from Outside (Unlocked): Depress the lever handle.
• To Open from Outside (Locked): Insert the correct key into the cylinder, turn to unlock, then depress the lever handle.

6. Maintenance

Regular maintenance ensures the longevity and smooth operation of your 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-based lubricant or a silicone-free lock lubricant into the keyway. Do not use oil-based lubricants, as they can attract dust and debris.
• Check Fasteners: Periodically check all mounting screws and bolts for tightness. Loose fasteners can lead to excessive wear or malfunction.
• Inspect for Wear: Examine the latch bolt, levers, and strike plate for signs of wear or damage. Replace worn components as necessary.

7. Troubleshooting

If you encounter issues with your lock, try these common troubleshooting steps:

• Lever is Stiff or Binding:
  • Check if mounting screws are overtightened. Loosen slightly and re-test.
  • Ensure the latch bolt is properly aligned with the strike plate.
  • Apply lubricant to the latch mechanism and keyway.
• Key Does Not Turn or Is Difficult to Insert:
  • Ensure you are using the correct key.
  • Check for debris in the keyway. Use compressed air to clear if necessary.
  • Apply graphite lubricant to the keyway.
  • If using an SFIC, ensure it is fully seated and correctly installed.
• Door Does Not Latch Securely:
  • Verify the strike plate is correctly aligned with the latch bolt. Adjust if needed.
  • Check for any obstructions in the door frame or strike plate opening.
• Lever is Loose:
  • Tighten the mounting screws that secure the lever assemblies. Do not overtighten.

If these steps do not resolve the issue, contact Sargent customer support or a professional locksmith.
