Mercedes-Benz MB100 Central Locking Motor Replacement Parts

The MB100 is a light van and minibus built roughly from the late 1980s into the 1990s, and central locking was not a standard or widely fitted feature on this model — it was a very basic, commercially focused vehicle and the vast majority left the factory without any central locking system whatsoever. Because there was no central locking system fitted, there would be no central locking motor to source. If your MB100 does have central locking, it is almost certainly an aftermarket retrofit rather than a factory-fitted system, so you would need to source a compatible aftermarket actuator rather than a genuine Mercedes MB100 part.

It is very unlikely to be a genuine OEM fitment, as the MB100 was not factory-equipped with central locking in any of its standard variants. Any central locking motor on an MB100 would be from an aftermarket kit, and the actuator you need would depend entirely on which brand and type of kit was installed. We'd recommend checking with the seller or a breaker about the specific aftermarket system on your vehicle before purchasing anything.

Because the MB100 was not fitted with factory central locking, there is no OEM Mercedes donor vehicle whose motor would slot straight in as a like-for-like replacement. If your van has a retrofitted system, the motor required is matched to the aftermarket kit, not to the vehicle model, so a Mercedes part from a Sprinter or Vito would not necessarily be compatible. Your best route is to identify the brand of the retrofit kit already on the vehicle and source a replacement motor for that specific kit.

If your MB100 door lock is not operating correctly, the most likely culprits on this model are the mechanical door lock barrel, the door lock linkage rods, or the door handles themselves — all of which are purely mechanical on a vehicle without factory central locking. If a previous owner has added an aftermarket central locking or alarm kit, the actuator motor within that kit may have failed, but that is a generic aftermarket part rather than a Mercedes-specific one. A breaker familiar with commercial vehicles from this era may still be able to help you identify the right mechanical components for the door lock mechanism.
