Purpose and function of the lock

The presented lock is dedicated to the rear right door panel in W163 series models, which guarantees compatibility with the factory body structure. The component is responsible for secure door locking, proper operation with both the exterior and interior handles, and stable retention of the door in the closed position while driving.

By maintaining the original geometry of the mechanism, the lock allows for the maintenance of the correct door alignment relative to the body, which is important for both acoustic comfort and the tightness of the seals.

Benefits of using an original Mercedes lock

Choosing an original door lock for a Mercedes translates into a number of practical advantages:

• factory fit to the door structure and body pillar,
• proper cooperation with existing linkages and handles,
• preservation of the door closing characteristics intended by the manufacturer,
• reduction of the risk of play, rattling, and leaks in the rear right area of the vehicle.

For the user, this means more predictable mechanism operation, stable locking, and comfortable door handling without the need for additional modifications.

Installation characteristics

The lock has been designed as a component intended for a specific location on the vehicle – rear, right side. Thanks to this, installation is carried out based on existing mounting points in the door, without the need to interfere with the sheet metal structure or modify mounting holes.

With a correctly selected body model, it is possible to use the existing wiring harness and door equipment, which shortens service time and facilitates the restoration of full functionality of the rear right door.

Condition of the component and service application

The offered lock is a used component, which allows for an economical repair of the door zone while maintaining the original manufacturer's specifications. This type of solution is particularly beneficial for post-accident repairs, replacement after wear and tear, or when dealing with issues related to closing and locking the rear right side.

In practice, the lock can be used both as a direct replacement for a damaged component and as a part used during comprehensive door renovation, which also includes hinge adjustment, seal replacement, or correcting the door alignment relative to the body.
