4. Setup and Installation
This section provides general guidance for installing the LOCINOX Vinci gate lock. Refer to the detailed installation template and specific instructions provided with your product for precise measurements and steps. Professional installation is recommended.
4.1. Pre-Installation Checks:
- Ensure the gate frame is suitable for surface mounting the lock.
- Confirm you have all necessary tools (drill, measuring tape, screwdriver, etc.).

4.2. Reversing the Latch Bolt (if necessary):
The lock is designed to be reversible. If the latch bolt is not oriented correctly for your gate's opening direction, follow the manufacturer's instructions to reverse it. This typically involves removing a retaining screw, rotating the bolt, and re-securing it.
4.3. Mounting the Lock:
- Position the lock body on the gate frame at the desired height.
- Mark the drilling points for the mounting screws and the spindle hole.
- Drill pilot holes as indicated by the template.
- Secure the lock body to the gate frame using the provided mounting hardware.
- Install the strike plate on the gate post, ensuring proper alignment with the latch bolt.
- Test the gate's operation to ensure smooth locking and unlocking.

5. Operating Instructions
5.1. Setting/Changing the Code:
The LOCINOX Vinci lock features a fully mechanical code panel. To set or change the access code, refer to the specific instructions provided by Locinox for your model. This process typically involves accessing the internal mechanism (often by removing the cover) and repositioning the code pins or tumblers according to your desired code sequence. Ensure the cover is securely re-attached after changing the code.
- Important: Always test the new code with the gate open before closing it to avoid accidental lockout.
- Keep a record of your code in a secure location, separate from the lock.
5.2. Unlocking with the Code:
- Enter your pre-set access code on the keypad.
- Once the correct code is entered, the handle will engage.
- Turn the handle to retract the latch bolt and open the gate.
- Release the handle to allow the latch bolt to extend and secure the gate when closed.
5.3. Key Override Function:
The lock includes a key cylinder for manual override. Insert the provided key into the cylinder and turn it to unlock the mechanism, allowing the handle to operate without entering the code. This is useful for temporary access or in situations where the code is forgotten.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your LOCINOX Vinci gate lock.
- Cleaning: Periodically clean the exterior of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or internal components.
- Lubrication: Apply a small amount of silicone-based lubricant to the moving parts of the latch bolt and key cylinder annually, or as needed, to ensure smooth operation. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly check all mounting screws and bolts for tightness. Inspect the code panel buttons, handle, and key cylinder for any signs of wear or damage. Ensure the polyamide rain and dust cover is intact and properly seated.
- Drainage: Ensure the lock's drainage holes (if present) are clear of debris to prevent water accumulation.
