1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your LOCINOX Surface Mounted Gate Lock, model LAKQ3030 U2. Please read these instructions carefully before proceeding with installation or use to ensure proper function and longevity of the product.
The LOCINOX LAKQ3030 U2 is a robust, surface-mounted gate lock designed for durability and ease of use. Constructed from stainless steel with an ISO 9227 KTL / E-coated lock box, it offers excellent resistance to corrosion. Key features include a reversible daybolt for versatile application and 20mm continuous adjustability for precise fitting.
2. Setup and Installation
Safety First: Always wear appropriate personal protective equipment (PPE) such as safety glasses and gloves during installation. Ensure the gate is stable and secured before beginning work.
2.1 Tools Required
- Drill
- Drill bits (appropriate for gate material)
- Measuring tape
- Pencil or marker
- Screwdriver set
- Wrench set
2.2 Installation Steps
- Positioning: Determine the desired height and position for the lock on your gate frame. The lock is designed for gate profiles between 30mm and 50mm.
- Marking: Place the lock body against the gate frame and mark the four fixing points for drilling. Also, mark the position for the key cylinder and the daybolt.
- Drilling: Carefully drill pilot holes at the marked fixing points. Drill the necessary holes for the key cylinder and daybolt to pass through the gate frame.
- Mounting the Lock Body: Secure the lock body to the gate frame using the provided screws and the four-hole fixing system. Ensure the lock is level and securely fastened.
- Installing the Strike Plate: Close the gate and mark the position for the strike plate on the gate post, ensuring proper alignment with the daybolt and nightbolt. Install the strike plate securely.
- Adjusting the Daybolt: The daybolt offers 20mm of continuous adjustability. Adjust its projection to ensure smooth operation and secure engagement with the strike plate. The daybolt is reversible to suit both left and right-handed gate applications. To reverse, pull the daybolt out, rotate 180 degrees, and reinsert.
- Testing: Operate the lock with the key several times to ensure smooth locking and unlocking. Check that the daybolt and nightbolt engage correctly with the strike plate.

3. Operating Instructions
The LOCINOX LAKQ3030 U2 gate lock is designed for straightforward operation.
- Locking: Insert the key into the cylinder and turn it to extend the nightbolt, securing the gate. Remove the key.
- Unlocking: Insert the key into the cylinder and turn it to retract the nightbolt. The gate can then be opened.
- Daybolt Function: The daybolt automatically retracts when the gate handle is operated, allowing the gate to open. When the gate closes, the daybolt springs back into the strike plate, holding the gate shut without requiring the key.
- Reversible Daybolt: The daybolt can be easily reversed to accommodate both left-opening and right-opening gates. Refer to Section 2.2, Step 6 for instructions.
4. Maintenance
Regular maintenance ensures the optimal performance and extends the lifespan of your LOCINOX gate lock.
- Cleaning: Periodically clean the lock body and internal mechanisms to remove dirt, dust, and debris. Use a soft cloth and a mild, non-abrasive cleaner. Avoid harsh chemicals that could damage the finish.
- Lubrication: Apply a small amount of graphite-based lubricant or a silicone spray to the key cylinder and moving parts of the daybolt and nightbolt annually, or as needed, to ensure smooth operation.
- Inspection: Regularly inspect all screws and fixings to ensure they remain tight. Check for any signs of wear or damage to the lock components, strike plate, or gate hinges. Address any issues promptly.
- Corrosion Resistance: The stainless steel construction with KTL / E-coated lock box provides excellent corrosion resistance, withstanding 1000 hours of salt spray testing. However, regular cleaning and inspection are still recommended, especially in harsh environments.
5. Troubleshooting
If you encounter issues with your gate lock, refer to the following common problems and solutions:
- Key is stiff or difficult to turn:
- Apply a graphite-based lubricant to the key cylinder.
- Check if the key is bent or damaged. Use only original or properly cut duplicate keys.
- Daybolt or nightbolt does not engage or retract smoothly:
- Inspect for obstructions in the strike plate or around the bolt mechanisms.
