Purpose and function in the vehicle

The presented lock is designed for installation in the rear area, on the right side of the vehicle body, where it is responsible for mechanical locking and integration with the keyless entry system. The design is adapted to the architecture of the Mercedes W221 door, which allows for maintaining the factory geometry of guides, linkages, and mounts.

Thanks to the integration with the actuator, this component enables smooth control from the central locking system, and the use of the Keyless solution allows for convenient opening and closing of the door without the need to use a traditional key.

Construction and compatibility with the Keyless system

The Mercedes W221 Door Lock Rear Right O/S Actuator Catch Keyless combines a mechanical latch and the part responsible for cooperation with the keyless system in one housing. This solution:

• facilitates installation in factory mounting points in the door,
• ensures consistent operation with the vehicle's electrical installation,
• maintains proper cooperation with the external and internal door handle,
• allows for maintaining the functionality of the comfort access system.

The original origin from the Mercedes group promotes maintaining the appropriate operating characteristics of the lock, including closing force, response to signals from the remote control, and correct cooperation with body modules.

Condition, origin, and advantages of using a used part

The offered item is a used part, sourced from the dismantling of a Mercedes vehicle. Such components are often chosen for repairs of premium class vehicles because they allow for maintaining the original construction and operating parameters while optimizing service costs.

Using an original lock with an actuator and Keyless function in the rear right part of the body:

• reduces the risk of problems with fitting to the door and bodywork,
• promotes trouble-free cooperation with comfort electronics,
• allows for maintaining the consistency of operation of all locks in the vehicle.

Selecting the lock for a specific Mercedes W221 unit

When selecting a rear right door lock for a Mercedes W221, it is crucial to verify compatibility with the vehicle's equipment, especially with the keyless system. It is worth comparing the mechanism construction and the type of electrical connector with the component factory-installed in the car to ensure full functionality after installation.

In case of doubt, it is also helpful to refer to the manufacturer's markings and information assigned to the Brand parameter, as well as data regarding the placement on vehicle, which facilitates unambiguous confirmation that this is a lock intended for the rear right side of the body.
