Lock Purpose and Function

The presented lock is dedicated to the rear right door wing in Mercedes compact class models. It is responsible for the mechanical locking and unlocking of the door, cooperation with the central locking system, and proper closing of the door wing against the body. Thanks to its factory design, the correct geometry of rods, latches, and the locking mechanism is maintained, which translates to secure closing without play or jamming.

Construction and Technical Compatibility

As a component from the Locks and Latches group, the rear right door lock has been designed for specific mounting points in the door and for factory installation sockets. This means:

• appropriate placement of mounting holes relative to the door panel,
• adaptation for standard rods and interior/exterior handles,
• proper cooperation with the vehicle's factory locking system.

This ensures an organized installation process, without the need for modifications to the door structure or the use of additional adapters.

Benefits of Using an Original Lock

Using an original rear right lock in a Mercedes W177 / W247 allows for maintaining the consistency of the entire locking system. In practice, this means:

• stable mechanism operation during repeated opening and closing of the door,
• maintenance of factory safety parameters related to door closure,
• no issues with alignment to the body edges and seals.

A used OEM part is also a reasonable compromise between cost and quality – you receive a part designed specifically for the given model, maintaining its original construction and operating characteristics.

Installation and Service Application

The rear right door lock is suitable for both typical repairs due to wear and tear, as well as for damage resulting from collisions or interference with the door structure. Thanks to its factory fit, it is possible to:

• restore proper door closing after body repairs,
• eliminate problems with incomplete closure or spontaneous opening of the door wing,
• maintain correct cooperation with the vehicle's existing installation.

Choosing an original lock is particularly important in vehicles where maintaining the original functionality of the locking system and compatibility with other body elements is crucial.
