Mercedes-Benz EQB Central Locking Motor Replacement Parts

The EQB is a fully electric vehicle built on Mercedes-Benz's modular electric architecture, and like most modern Mercedes models it uses an electronic central locking system integrated into the door latch assemblies rather than separate, standalone central locking motors as older vehicles had. There is no discrete central locking motor unit fitted to any variant of the EQB. What you are most likely looking for is the door latch actuator assembly, which contains the locking mechanism built in — search for 'EQB door latch actuator' or 'EQB door lock actuator' when requesting quotes from breakers.

On the EQB, the locking and unlocking function is handled by an electrically operated latch actuator built into each door latch unit, so the part you need is the door latch actuator for the affected door, specifying whether it is the NS (nearside/passenger) or OS (offside/driver) and front or rear. There is no separate central locking motor to replace. When contacting a breaker, quote your registration so they can confirm the correct latch unit for your exact build.

The Mercedes-Benz EQB was introduced in the UK in 2022 as an X243-platform model and, as of 2024, has not received a significant generational change or full facelift that is widely documented as altering door hardware. Because the EQB is a relatively new and single-generation model at this point, compatibility across the production run is plausible, but you should confirm the part number against your registration with the breaker before purchasing, as mid-cycle running changes can affect latch assemblies without a formal facelift announcement.

Trim level does not affect the door latch actuator fitment on the EQB — the locking mechanism is the same across trim lines including standard, AMG Line, and AMG Line Premium variants. The differences between trims are cosmetic, such as alloy wheel design, interior finish, and exterior styling, none of which influence the latch assembly. Confirm your door position (NS/OS, front/rear) and your registration with the breaker, and trim level need not factor into your search.

The EQA and EQB share the same X243 platform and many components, so cross-compatibility of door latch actuators is a real possibility, but this is not something that should be assumed without verification. Body dimensions and door sizes differ between the two models, which can mean different latch unit specifications. Ask the breaker to cross-reference the part numbers from both vehicles against your EQB's registration before agreeing to purchase.

Used EQB parts are available through UK vehicle dismantlers (breakers) who specialise in modern or electric vehicles, and Findapart lets you request quotes from multiple breakers at once to compare prices. Because the EQB is a relatively recent model, used stock may be limited but is growing as earlier cars enter the salvage market. Always give the breaker your full registration and specify which door position you need — NS or OS, front or rear — to make sure you receive the correct actuator.
