Purpose and fitment for Mercedes W203

The presented cover is a component from the Door Handles group, designed specifically for the front right door in Mercedes C-Class W203 generation models. The design, intended for exterior mounting, ensures proper positioning relative to the lock cylinder and handle, which translates into stable mounting and correct operation of the opening mechanism.

The original mounting geometry allows for installation in place of the factory component without the need for modifications, which is particularly important for post-accident repairs or the replacement of damaged body details.

Tanzanite Blue Metallic color – visual consistency of the body

The cover is finished in the Tanzanite Blue Metallic – 359 shade, characteristic of the Mercedes paint palette. Thanks to this, the element allows for maintaining color consistency with the factory-painted door and handle, reducing the need for additional painting during repairs in the area of the front right side of the vehicle.

The metallic structure of the paint provides appropriate color depth and matches the character of the premium class body, which is important both for precise body and paint repairs and for the aesthetic restoration of exterior details.

Performance characteristics and installation

The Mercedes W203 Door Handle Lock Cylinder Cover Front Right O/S Tanzanite Blue is a used component, which in practice means it comes from disassembly and is intended for further use after proper installation. This type of component is particularly useful when:

• the factory cover has been damaged or lost due to a collision or vandalism,
• the complete passenger side door handle is being replaced,
• the side part of the body is being restored while maintaining original design solutions.

Due to its factory origin, the cover maintains proper dimensional tolerances, which facilitates installation and minimizes the risk of leaks or looseness around the handle and lock cylinder.

Benefits of using an original door handle cover

Using an original lock cylinder cover in a color matched to the body provides a number of practical benefits:

• Aesthetic finish of the handle area – no visible gaps, voids, or non-original plugs.
• Color consistency – maintaining a uniform Tanzanite Blue Metallic shade across the entire door surface.
• Compatibility with the factory mechanism – fitment to the design of the handle and lock cylinder in the Mercedes W203.
• OEM-compliant solution – no need to adapt universal replacements.
