Purpose and function of the component

The described lock cylinder cover is part of the Door handles group and operates in the immediate vicinity of the front right door lock mechanism. Its purpose is to:

• protect the lock cylinder from dirt and moisture,
• provide a stable closure for the technological opening in the handle,
• maintain the factory styling line of the door,
• ensure proper access to the cylinder during mechanical operation.

Due to its correct profile, the cover works in harmony with the handle and the door panel, limiting the risk of dirt entering the mechanism, which translates into more reliable lock operation in daily use.

Color and body fitment

The component is finished in Calcite White - 650, used as a factory standard in many Mercedes M-Class W164 generation vehicles. The use of the original shade allows for:

• maintaining a uniform color scheme across the entire side of the body,
• avoiding tone differences typical of unpainted aftermarket replacements,
• shortening repair time – no need for additional preparation or painting.

The precise fitment for the front right door ensures that after installation, the cover creates a flush surface with the handle, without unwanted gaps or tension.

Technical characteristics and installation

The lock cylinder cover has been designed specifically for the Mercedes W164 body, taking into account the geometry of the front passenger-side door. This means that:

• the mounting profile corresponds to the factory attachment points in the handle,
• the edge shape harmonizes with the door contours,
• the dimensions are adapted to the standard lock cylinder used in this model.

The used component allows for an economical repair of the door area without interfering with the lock structure or replacing the entire handle. In practice, this translates into lower costs for restoring full functionality and aesthetics to the door.

Application in service practice

The Mercedes W164 Lock Cylinder Cover Front Right O/S Handle Calcite White is suitable for both post-accident repairs and the replacement of worn or damaged body components. It is particularly useful when:

• mechanical damage has occurred to the passenger-side handle,
• the original cover was lost during previous service work,
• it is necessary to restore a consistent look to the door after local painting.

Thanks to the preservation of the factory color and shape, the component allows for the quick restoration of the vehicle's original appearance, which is significant for both aesthetic and practical reasons.
