Purpose and function of the door lock latch

The presented door lock latch is dedicated for installation in the rear right part of the vehicle, in the side body area. It is responsible for transferring the movement of the driver's or passenger's hand to the locking mechanism, which translates into smooth opening and closing of the door and proper latching of the door panel against the bodywork.

The placement on the vehicle in the rear right door area makes this component significant both for passenger entry comfort and for safety – proper lock operation reduces the risk of accidental opening while driving.

Construction and body fitment

As a part from the Doors and door panels group, the lock latch works with the door skin structure, the internal locking mechanism, and the guides. The geometry of the mounts and the kinematics of the lever are adapted to the specific construction of the doors in the W901 series models, which facilitates installation and allows for maintaining factory-standard fitment of the components.

Properly selected mounting points and routing of cables or rods (depending on the specific door configuration) ensure stable operation of the mechanism during repeated opening and closing, without excessive play or jamming.

Benefits of using an original Mercedes component

Using a door lock latch dedicated to Mercedes vehicles allows for maintaining the structural integrity of the body and avoiding problems typical of replacements with imprecise fitment. The original geometry translates into:

• correct positioning of the handle relative to the door skin,
• proper cooperation with the lock and latching mechanism,
• stable door closing without the need for excessive adjustment.

Thanks to this, the user receives a component that allows restoring the original functionality of the door after a collision, operational wear, or a previous improper repair.

Condition and service application

The component is offered in used condition, which makes it an attractive service solution for repairs of vehicles used intensively or with higher mileage. This type of part will work particularly well in situations where the priority is to restore full door functionality while maintaining reasonable repair costs.

The rear right door lock latch can be used both when replacing a damaged mechanism after a road incident and during gradual restoration of the side body area when problems with opening, jamming, or incomplete closing of the door occur.

Support for selection and expansion of the door area
