5. Setup and Installation
This lock body is designed as a replacement part for doors that utilize a profile lock cylinder and 6068 mortise type. Follow these steps for installation:
- Preparation: Ensure the door mortise is compatible with the 6068 standard and the dimensions of this lock body (24x240mm faceplate, 60mm backset, 68mm center distance).
- Remove Old Lock Body: Carefully remove the existing lock body from the door. This typically involves unscrewing the faceplate and any securing screws within the mortise.
- Insert New Lock Body: Gently slide the QXCIVR 6068 lock body into the mortise cutout in the door. Ensure it sits flush and correctly aligns with the existing holes for the cylinder and handle spindle.
- Secure Lock Body: Fix the new lock body in place using the provided M5*60MM screws. Tighten them securely but do not overtighten.
- Install Cylinder and Handles: Install your compatible lock cylinder and door handles according to their respective instructions.
- Test Functionality: Before closing the door, test the operation of the latch, deadbolt, and hook (if applicable) with the door open. Ensure smooth movement and proper engagement.

6. Operating Instructions
The QXCIVR 6068 lock body is designed for secure operation in storm doors, patio sliding doors, and other applications requiring a profile lock cylinder. It features safe pins for enhanced security.
- Key Operation: Insert the key into the compatible lock cylinder and turn to engage or disengage the deadbolt and hook mechanism.
- Handle Operation: Use the door handle to retract the latch bolt for opening the door.
- Hook Mechanism: The integrated hook provides additional security, engaging with the strike plate when the deadbolt is thrown.
- New Keys: If using brass keys for a locksmith to make new keys, it is recommended to gently knock the cylinder before use. This helps prevent any potential copper scrapes from getting stuck inside and causing jamming.

7. Maintenance
Proper maintenance ensures the longevity and smooth operation of your lock body.
- Cleaning: Wipe the visible parts of the lock body and faceplate with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the stainless steel finish.
- Lubrication: Periodically apply a small amount of graphite-based lubricant or a silicone-based spray specifically designed for locks into the keyway of the cylinder and moving parts of the lock mechanism. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly inspect the lock body and its components for any signs of wear, damage, or loose screws. Tighten any loose screws as needed.
8. Troubleshooting
If you encounter issues with your lock body, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Key is difficult to turn or stuck. | Lack of lubrication, debris in keyway, bent key, or misaligned cylinder. | Apply lock lubricant to the keyway. Check the key for damage. Ensure the cylinder is properly installed and aligned. |
| Latch bolt or deadbolt does not retract/extend smoothly. | Friction, debris in the mechanism, or misaligned strike plate. | Lubricate the moving parts of the lock body. Clean any visible debris. Check and adjust the strike plate alignment on the door frame. |
| Door does not close properly after lock body installation. | Lock body or strike plate misalignment. | Re-check the installation of the lock body and ensure it is flush. Verify the strike plate on the door frame is correctly aligned with the latch and deadbolt. |
