Purpose and technical function

The presented lock cylinder is dedicated to the front right door of the Mercedes S-Class W220 generation. The component works with the factory exterior door handle, responsible for the mechanical part of the door locking and unlocking process and the correct transmission of the key movement to the locking mechanism.

Thanks to the preservation of the original geometry and fitment to the door structure, installation is predictable, without the need for modifications or adjustments to the mounts. This solution is particularly beneficial for repairs following mechanical damage or break-in attempts, where it is necessary to replace the cylinder itself while retaining the other door components.

Color and visual fitment

The component is finished in Chalcedony Blue Metallic, which allows for an aesthetic match to bodywork in the same color. In practice, this means reducing the need for additional paint work in the door handle area, thereby shortening repair time and reducing costs.

Selecting a lock in the correct color is particularly important for precision repairs, where maintaining a uniform paint surface and minimizing shade differences between individual body panels is essential.

Benefits of using an original lock

Using an original lock cylinder in a Mercedes W220 offers a number of practical advantages:

• secure fitment to the factory door handle and locking mechanism,
• maintenance of compatibility with the passenger side door structure,
• stable mechanical operation during daily vehicle use,
• reduced risk of installation problems typical of aftermarket replacements.

For workshops and private users, this means a more predictable service process and a lower risk of needing to revisit the door mechanism.

Condition and service application

The offered lock comes from dismantling and is sold as a used original component. Such components are a popular choice for repairs of vehicles that are several or more years old, where a combination of reasonable costs and maintaining the factory design is important. It is suitable for both post-accident repairs and the replacement of worn or damaged door mechanisms.

In the case of more extensive work on the vehicle's locking system, it is worth considering a simultaneous inspection of other door mechanism components to avoid returning to the same service area in the near future.
