Purpose and function of the mechanism

The presented door lock is dedicated for installation in the rear right part of the Mercedes CLA C117 vehicle. It is responsible for working with the handle, rods, and control system, enabling smooth locking and unlocking of the door panel from both the inside and the outside. Thanks to its factory design, the mechanism maintains the correct operating geometry, which reduces the risk of the door jamming, improper closing, or play in the lock. This is particularly important in daily use, where the door is one of the most frequently used body components.

Construction and fitment to the body

The lock mechanism has been designed for the specific architecture of the rear right door in the Mercedes CLA C117, which ensures precise fitment with the door skin, frame, and internal components. The appropriate placement of mounting points facilitates installation in factory holes without the need for modifications. The system works with factory rods and levers, ensuring that after correct installation, the original operating characteristics of the handle, lock, and internal control buttons are maintained. Such a solution allows for maintaining the consistency of the entire vehicle locking system.

Benefits of using an original lock

• Compatibility with the rear right door construction in the Mercedes CLA C117.
• Replication of factory door locking and unlocking performance.
• Possibility of integration with the existing control system and door hardware.
• Stable mounting in original body points. As a component from the Locks and latches group, the mechanism influences the comfort of using the vehicle, reducing problems with closing and improving the overall sense of solidity of the door during daily operation.

Condition, origin, and environmental aspect

The offered door lock comes from disassembly and is a used component, which allows for combining rational repair costs with maintaining the manufacturer's original specifications. Choosing such a solution is also a support for the secondary parts market and a reduction in the amount of waste generated during vehicle servicing. If you want to better understand how using parts from disassembly affects the environment and service budget, it is worth reading the material describing the practical benefits of the circular economy: circular economy in your garage.
