Purpose and function of the component

The presented lock cover is an integral part of the external door handle, responsible for the aesthetic and technical finishing of the lock cylinder area. It is mounted on the front right door, in the location factory-specified by the manufacturer, which ensures proper guidance and protection of the cylinder mechanism as well as a consistent appearance of the entire handle.

The element works with the factory door handle and lock mechanism, forming a complete assembly responsible for opening and closing the passenger-side door. This makes it possible to maintain the original ergonomics of operation and proper fitment with other door panel components.

Estoril Blau Metallic B45 color and visual fitment

The cover is finished in Estoril Blau Metallic – B45, characteristic of the sporty configurations of the BMW F30/F31 series. This shade allows for maintaining a uniform stylistic line of the body without the need for additional painting, provided that the other elements are in the same paint code.

The factory surface finish ensures consistency with the remaining body panels, and the appropriately shaped geometry of the cover allows for precise fitment to the handle and adjacent door elements. This solution reduces the risk of gaps, unevenness, or unwanted stress in the handle area.

Benefits of using an original lock cover

Using an original lock cover in Estoril Blau Metallic brings a number of practical and visual benefits:

• maintaining the factory exterior appearance of the door without differences in paint shade,
• proper fitment with the handle and door panel, in accordance with the manufacturer's design,
• protection of the lock cylinder insert against external factors,
• no need for mounting adaptations or interference with the door structure.

Thanks to this, the element serves as a functional complement to the existing handle, allowing for the restoration of full efficiency and aesthetics after damage or wear of the previous cover.

Mounting characteristics and application

The cover is designed for installation in the front, right part of the body, in the passenger door area. The construction corresponds to factory solutions used in the F30/F31 series, which allows for installation in place of the original element without the need to modify mounts or guides.

As a part from the Door handles category, it contributes to the complete assembly responsible for door operation, and its correct attachment affects the comfort of vehicle use and the visual consistency of the side of the body.

Condition and origin

The element comes from the original BMW production line and is offered as a used part, which allows for economical repair while maintaining compliance with factory specifications. This type of component is particularly useful for accident repairs, spot body corrections, or replacing individual fragments of the handle without the need to purchase the entire set.
