Vehicle Application and Function

The presented lock is designed for the left front door area, responsible for the mechanical locking of the door leaf and its integration with the central locking system. The built-in electric actuator allows for control via remote, an interior button, and the key, maintaining the full comfort system functionality as intended by the manufacturer.

The original design dedicated to the Mercedes C-Class W204/S204 ensures the correct positioning of rods, latches, and connectors, which translates to stable operation of the exterior and interior door handles, proper closing, and repeatable locking without the need for modifications.

Mechanism Construction and OEM Advantages

The mechanism combines a mechanical part responsible for latching the door with an electrical module that controls the lock bolt position within a single housing. Using an original Mercedes solution ensures:

• compatibility with the factory electrical system and door wiring harness,
• correct mounting points to the door panel and frame,
• proper cooperation with factory door handles and rods.

This allows for installation according to service standards, without the need for adaptations, custom brackets, or wiring modifications. This is important for both workshops and users expecting a predictable repair outcome.

Condition, Fitment, and Service Application

This part is from the used OEM parts group, which practically means retaining original geometry, mounting points, and compatibility with factory safety and comfort systems. For Mercedes W204/S204 vehicles, this solution is particularly beneficial for:

• repairing collision damage to the left front door area,
• resolving central locking faults in a specific door,
• restoring proper locking after wear of the original lock.

Using an original lock with an actuator helps reduce the risk of issues with door closing, incorrect locking, or comfort system errors, which often occur with aftermarket replacements of uncertain origin.

Benefits of Installation in Mercedes W204 / S204

Choosing this left front door lock primarily means maintaining the factory standard of operation for the locking system. The mechanism is structurally adapted to the door's geometry, which facilitates adjustment and reduces installation time. For workshops, this means more efficient service, and for the user, a predictable repair result and correct central locking operation in daily use.
