Purpose and function in the vehicle

The described driver's door lock cylinder lock is a component of the locking system that works with the handle mechanism and the central locking system. Its task is to transfer the movement of the key to the latch mechanism, which enables mechanical opening and closing of the driver's door, even in emergency situations when the electrical system is inactive.

The placement on the vehicle specified as rear indicates that the part is associated with the rear body area, which is important when assembling a complete set of locks and cylinders in the car. This allows for consistent operation of the entire locking system, covering both doors and rear body elements.

Compatibility and identification parameters

The product belongs to the technical category Trunk lids and rears, which makes it easier to find in body part catalogs. The manufacturer's designation and interchangeable numbers allow for precise identification of the element in service documentation and parts selection systems, as well as verification of compatibility with a specific body version.

Additionally, in the store system, the part has an assigned identifier SKU, and the technical documentation includes the OEM part number and available interchangeable numbers. This allows a mechanic or service advisor to quickly confirm the fit of the part to a specific vehicle instance.

Brand, origin, and condition

The offered lock is a Mercedes brand component, which means compliance with the factory manufacturing and design standards used by this manufacturer. The solutions used in the mechanism are designed to work with original handles, rods, and the central locking system, which reduces the risk of installation problems.

The part is offered as used, which in practice means it comes from disassembly and has been verified for its suitability for further operation. This type of component is a good choice for maintenance repairs when preserving the original design while optimizing service costs is a priority.

Benefits of using an original lock
