Construction and Function of the Lock Actuator

The door lock actuator is responsible for mechanical locking and transmitting motion from the handle and central locking actuator to the lock latch. The design anticipates cooperation with factory linkages, guides, and the door's wiring harness, facilitating installation at original mounting points.

Key functions include:

• Stable door locking during driving and while parked, reducing the risk of accidental opening.
• Cooperation with the central locking system, enabling synchronized opening and closing of all doors.
• Transmission of signals to comfort systems (e.g., door open status information), which is important for interior lighting and safety systems.

Condition, Origin, and Service Application

The offered actuator is from the Mercedes Group and is a used part, making it an attractive cost-effective alternative to a new lock while maintaining factory construction. This type of part is often chosen by workshops specializing in the Mercedes brand when maintaining the vehicle's original specifications is required.

The rear right door lock actuator is suitable for situations such as:

• Mechanical damage to the lock after a collision or attempted break-in.
• Malfunctioning locking of one door while others operate correctly.
• Problems with opening from the inside or outside, resulting from wear of the factory mechanism.

Benefits of Using an Original Lock Actuator

Using an original lock actuator in a Mercedes W221 maintains the door's structural integrity and the predictable operation of the comfort system. Key advantages include:

• Factory fit for the rear right door – no need for modifications to mounts or linkages.
• Compatibility with vehicle electronics – correct cooperation with control modules and sensors.
• Stable central locking operation – reduced issues with partial opening or no response to remote signals.
