Purpose and body fitment

The presented lock is dedicated to the front right door of the Mercedes A-Class W168 generation. Its placement in the passenger door area ensures proper latch guidance, compatibility with both external and internal door handles, and correct positioning relative to the door pillar. Thanks to a design consistent with factory specifications, proper alignment with the door panel and sealing elements is maintained.

Mechanism construction and actuator function

The mechanism combines the mechanical part of the lock and the actuator responsible for central locking operation in a single housing. The locking assembly transfers movement from the handle and lock cylinder to the locking pawls, while the actuator is responsible for:

• remote locking and unlocking of the door via remote control or the interior button,
• proper integration with the vehicle's electrical system,
• maintaining a stable closed position while driving.

This configuration helps maintain consistent central locking performance and minimizes the risk of play or doors failing to close properly on the passenger side.

Benefits of using an original door lock

Using a factory-spec lock with an actuator in the Mercedes A-Class W168 provides a range of practical advantages in daily operation:

• preservation of original mounting geometry within the door,
• proper compatibility with the factory central locking system and electrical wiring,
• appropriate rigidity of the connection to the door panel,
• reduction of risks related to door closing issues or latch rebound.

As a result, replacing a damaged component with one matching the vehicle's design allows for quick restoration of full door functionality without the need for modifications or adjustments to the mounts.

Condition and service application

The offered front right door lock is a component from the Doors and door panels category, intended primarily for service and repair applications. It is ideal for replacing a damaged mechanism following a collision, wear and tear, or central locking actuator failure. Installation in place of the factory lock allows for the retention of original cable routing and wiring harnesses, which facilitates workshop tasks and reduces repair time.
