Vehicle Application and Placement

The presented lock is dedicated for installation in the front right door area, meaning it works with the factory opening and closing mechanism on the passenger side. Its placement on the vehicle is precisely defined as front – right, allowing the part to be unambiguously matched to its specific mounting position without the risk of error.

Such specialized application ensures the correct geometry of operation for rods, strikers, and control elements, which translates to secure door locking and proper cooperation with the central locking system and vehicle safety systems.

Technical and Functional Characteristics

The lock belongs to the Locks and Latches group, which are components responsible for the mechanical and often electrical operation of door locking. The design of this type of component is engineered for:

• stable locking of the door leaf to the body pillar,
• cooperation with the external and internal door handles,
• withstanding the loads resulting from frequent opening and closing,
• integration with the central locking system and any position sensors.

Its original origin from the Mercedes group promotes adherence to proper dimensional tolerances, which facilitates installation and reduces the need for additional adjustments after fitting into the door.

Condition of the Part and Benefits of Using a Used Component

The offered lock is in used condition, which in practice means it comes from a dismantled vehicle and has been verified for further service. Choosing such a solution allows for reduced repair costs while maintaining original construction and compatibility with the vehicle's factory systems.

Using used components for door locks is a popular and rational service approach, especially for models where conformity with factory equipment and predictable mechanism behavior over the long term are important.

Why Choose an Original Mercedes Door Lock

Using an original lock in the front right door ensures the consistency of the entire locking system in the vehicle. Key advantages of this solution include:

• factory fit to the door and body pillar structure,
• predictable cooperation with the central locking system and electrical installation,
• preservation of the original operating characteristics of handles and latches,
• reduced risk of issues with door closing or locking.

This allows the lock to be used both as a repair part after a failure and as part of a preventative replacement for vehicles with intensive use.
