Purpose and technical function

The presented lock cylinder is a component from the Door handles group, responsible for the mechanical interaction between the key and the locking mechanism. It is mounted in the front right door, within the exterior handle, which allows for manual opening and closing of the vehicle using a key, even in the event of power issues or central locking electronic failure.

Its placement in the front-right area of the body ensures direct service access while protecting the cylinder from excessive dirt and mechanical damage. The design is adapted to the geometry of the door and handle in Mercedes W205 models, which translates into proper key guidance and repeatable mechanism operation.

Original origin and compatibility

The lock cylinder comes from the Mercedes product range, which means it maintains factory manufacturing standards, dimensional tolerances, and material quality. The original component ensures:

• proper fitment with the front right door handle,
• correct operation with the factory mechanical key,
• compatibility with the lock and linkage design in W205 doors.

As a result, installation does not require any modifications or adjustments, and the mechanism retains factory-like parameters in terms of operation and durability after replacement.

Performance characteristics of the used component

The item is offered in used condition, which in practice means it has been removed from a vehicle and was previously in service. This type of part is a good choice when the priority is to maintain the original lock design while optimizing repair costs. A secondary market lock cylinder allows you to:

• restore the efficiency of the mechanical door opening on the right side,
• maintain the consistency of the locking system with other door components,
• preserve the original character of the vehicle without using aftermarket replacements of uncertain quality.

Before installation, a standard inspection of the mechanism and, if necessary, basic lubrication maintenance is recommended to ensure smooth operation in the long term.

Benefits of using an original lock cylinder

Using an original lock cylinder in the front right door of a Mercedes W205 provides a number of practical service and operational benefits:

• Stable mechanism operation – proper key guidance, repeatable locking and unlocking of the door.
• Factory fitment – no installation issues, correct positioning relative to the handle and lock.
• Operational safety – maintaining the emergency vehicle opening function in the absence of power.
• Economical repair – the ability to replace the cylinder itself instead of the complete door module.

This solution is particularly beneficial for localized damage to the lock mechanism on the right side, while other door components remain functional.

Selection support and additional information

To ensure the correct selection of the lock cylinder, it is worth using the manufacturer's markings, such as the OEM part number and available interchangeable numbers, as well as verifying the placement on the vehicle against your specific unit. Additionally, checking the SKU designation in our catalog may be helpful to ensure the selected component matches your specific body configuration.

If you are planning a comprehensive repair or upgrade of the door area in your Mercedes and need other components from the same group, such as exterior handles, lock cylinders, or handle mechanisms, check the available parts in the Mercedes Door handles category.
