4. Setup and Installation
The AceMining lock cylinder is designed for quick and easy installation. Follow these steps carefully.
4.1. Measuring Your Existing Cylinder
Before installation, it is crucial to measure your existing lock cylinder to ensure you have the correct replacement size. The cylinder length is measured from the center of the fixing screw hole to each end of the cylinder (A and B). The total length (C) is the sum of A and B.

Image: Guide on how to measure a door lock cylinder. Measure from the center of the screw hole (D) to the outer edge of each side (A and B). The total length is C. Alternatively, measure the old lock cylinder directly.

4.2. Installation Steps
- Remove Old Screws: Locate and remove the fixing screw on the side of the door that holds the old cylinder in place.
- Remove Old Cylinder: Insert a key into the old cylinder and turn it slightly (approximately 15-20 degrees) to align the cam with the cylinder body. This allows the cylinder to slide out of the door.
- Insert New Cylinder: Insert a key into the new AceMining cylinder. Turn the key slightly to align the cam. Slide the new cylinder into the door, ensuring it is flush with the door edge.
- Secure New Cylinder: Re-insert the M5x65mm fixing screw and tighten it securely. Do not overtighten.
- Test Operation: Rotate the key from both sides of the door to verify smooth operation and proper locking/unlocking.
- Installation Complete: Your new lock cylinder is now installed.

5. Operating Instructions
Operating the AceMining lock cylinder is straightforward:
- Insert one of the provided keys into the keyway.
- Turn the key clockwise to lock the door and counter-clockwise to unlock it.
- This cylinder supports locking from both sides, meaning a key can be used from either the interior or exterior to operate the lock.
6. Maintenance
The AceMining lock cylinder is designed for long-lasting performance with minimal maintenance.
- Cleaning: Periodically wipe the visible parts of the cylinder with a soft, dry cloth to remove dust and grime. Avoid abrasive cleaners or solvents.
- Lubrication: If the key turning feels stiff over time, apply a small amount of graphite-based lubricant or a specialized lock lubricant into the keyway. Avoid oil-based lubricants as they can attract dust.
- Key Care: Keep your keys clean and avoid using them for purposes other than operating the lock. Damaged keys can harm the cylinder mechanism.
7. Troubleshooting
If you encounter issues with your lock cylinder, consider the following:
- Key is Stiff or Hard to Turn:
- Ensure the key is fully inserted into the keyway.
- Check if the key is bent or damaged. Try another key.
- Apply a small amount of lock lubricant as described in the Maintenance section.
- Cylinder Does Not Lock/Unlock:
- Verify that the door is properly closed and aligned with the frame.
- Check for any obstructions in the door frame or strike plate.
- Ensure the fixing screw is not overtightened, which can cause binding. Loosen slightly and re-test.
- Cylinder Feels Loose:
- Tighten the M5x65mm fixing screw.
If problems persist after attempting these solutions, please contact AceMining customer support.
