Purpose and function in the vehicle

The front right door lock mechanism in the Ford C-Max Mk2 is a key component of the driver's cabin access system. It is responsible for:

• mechanical door latching when closing,
• integration with the central locking system and door handles,
• stable retention of the door in the closed position while driving,
• proper response to opening signals from both the interior and exterior. Thanks to its specific design, the mechanism ensures consistent operation and precise engagement with the striker on the door pillar, which translates into user comfort and the reduction of unwanted play or rattling within the door area.

Construction and fitment for Ford C-Max Mk2

The offered lock belongs to the Locks and Latches category and is specifically designed for installation in the front right door of the second-generation Ford C-Max. The mechanism's construction is prepared for integration with the factory wiring harness and original door handles, facilitating installation as a direct replacement for the original part. The vehicle placement is clearly defined as front – right side, which minimizes the risk of error when selecting the part. As a result, the lock is properly matched to the geometry of the driver's door in right-hand drive versions, maintaining the correct position of mounting points and linkage connection points.

Condition, origin, and benefits of use

The mechanism comes from Ford, which ensures adherence to factory design standards and compatibility with the C-Max Mk2 body. The part is used, making it a cost-effective solution while maintaining the proper fit and functionality intended by the vehicle manufacturer. Using an original front right door lock allows you to:

• reduce problems with doors failing to close or opening unexpectedly,
• maintain proper operation with the central locking system and electrical installation,
• preserve the structural integrity of the door and body pillar,
• reduce installation time thanks to the factory-standard mounting point layout.

Selection by part numbers and technical compatibility

To ensure full compatibility, it is recommended to verify the part using the OEM number and available interchangeable numbers, as well as to compare the vehicle placement with the removed component. This selection method helps avoid installation issues and guarantees that the mechanism will work with the existing striker, wiring harness, and central locking control. In case of doubt, it is worth comparing the data with service documentation or the manufacturer's catalog, paying special attention to the body generation, installation side, and door type (front, right side).
