Purpose and Function of the Door Lock

The rear right door lock in the C117 body is responsible for securely closing the door leaf and proper locking while driving and stationary. This component works with the handle, rods, and the central locking control system, so its correct operation directly impacts the comfort of vehicle use and the safety of passengers.

Thanks to a design tailored to its specific mounting position in the body, the lock ensures proper latch guidance, stable holding of the door in the closed position, and repeatable mechanism operation with each opening and closing cycle.

Construction and Fit for Mercedes C117

Mercedes C117 Rear Right Door Lock has been designed as a dedicated part for the rear right side of the body, which translates to proper positioning of mounting points and compatibility with factory mounting holes. The appropriate geometry of the housing and guides allows for correct interaction with the window, seals, and door panel, without the need for modifications to the door structure.

Original origin from the Mercedes group promotes consistency with other components of the locking system – both mechanically and electrically. This allows the lock to work with the factory central control, comfort systems, and vehicle security features.

Benefits of Using an Original Lock

Using an original door lock for the rear right side of the body helps reduce the risk of problems with closing, play in the door leaf, or improper locking. A well-chosen part from the Locks and Latches category also facilitates subsequent service – the mechanic has access to a known design, and diagnosing potential faults is simpler.

The main advantages of this solution include:

• maintaining the factory operating characteristics of the locking mechanism,
• consistency with the existing control and security system,
• stable door locking during daily use,
• minimizing the need for installation modifications.

Item Condition and Service Application

The presented lock comes from disassembly, making it a cost-effective solution while maintaining the original manufacturer's design. This type of component is particularly useful for accident repairs, replacing a damaged mechanism after wear and tear, or for problems with rear right door locking.

Choosing a used, original lock allows for combining savings with maintaining Mercedes-specific mechanism operating parameters, which is especially important in vehicles equipped with advanced comfort and security systems.
