Purpose and function of the lock

The presented lock is dedicated for installation in the rear left part of the body, ensuring a proper fit for the door structure in the E-Class estate S202 and S210 models. The component is responsible for the mechanical locking of the door leaf, interaction with the door handle, and transferring movement from the opening and closing system to the lock latch.

By maintaining the original geometry and mounting points, the lock allows for stable seating in the door panel without the need for modifying the sheet metal or additional adjustment of mounting holes.

Construction and mounting compatibility

The lock has been designed by the vehicle manufacturer for precise cooperation with the factory handle mechanism, rods, and other door components. The construction provides proper guidance for moving parts, which reduces operating play and promotes consistent performance during repeated opening and closing.

The original origin from the Mercedes group means maintaining proper dimensional tolerances, which facilitates installation in place of the previous lock and allows for the use of existing mounting points and factory screws.

Benefits of using an original lock

Using a lock dedicated to a specific position on the vehicle brings a number of practical benefits:

• maintaining proper closing and locking of the rear left door,
• consistent cooperation with the factory handle and rod mechanism,
• reducing the risk of the door not closing properly or jamming,
• easier adjustment after installation thanks to the adjustment points provided by the manufacturer.

For the user, this means stable mechanism operation, improved comfort of using the door, and maintaining the structural integrity of the body.

Characteristics of the used component

The offered lock comes from a used vehicle, which allows for an attractive cost-to-functionality ratio. The component is intended for further service in the door system, representing a viable alternative to new components, especially in the case of maintenance repairs or restoring the functionality of older vehicles.

For many users, choosing a used part is a way to keep the vehicle in full working order on a reasonable budget, while maintaining the original design of the lock.
