Used Mercedes-Benz EQS Door Lock Mechanism

You'll need to confirm the side — NS (nearside, passenger/left) or OS (offside, driver/right) — and which door position (front or rear) the mechanism is for. The EQS is a 5-door saloon, so also confirm whether it's a front or rear door, as the mechanisms differ. Have your registration plate ready so the breaker can verify the exact specification against their parts.

The Mercedes-Benz EQS (V297) launched in 2021 and has run through to the current model, with a mid-cycle refresh introduced for the 2024 model year — so there is a potential boundary to be aware of. Within the pre-facelift range (2021–2023), mechanisms for the same door position and side are generally expected to be compatible, but whether a pre-facelift part crosses into the 2024 facelift version is something you should confirm with the breaker against both registrations before buying.

Trim and powertrain level do not affect the door lock mechanism — the 450+, 580 4MATIC, and AMG EQS variants all share the same 5-door saloon body structure, so the mechanisms are determined by door position and side, not by which drivetrain is fitted. You may find cosmetic differences on surrounding trim pieces, but the lock mechanism itself is not trim-specific. Confirm the door position (front/rear) and side (NS/OS) and you should be good to discuss compatibility with a breaker.

Yes, door lock mechanisms absolutely exist on the EQS — all cars, whether petrol, diesel, or fully electric like the EQS, have door lock mechanisms as part of the door latch assembly. Being a battery-electric vehicle has no bearing on whether this part is present; every door on the EQS requires a lock mechanism to secure it. You're looking for the right part, so proceed with confirming the door side and position with your breaker.

Yes, this matters significantly — the EQS saloon (V297) and the EQS SUV (X296) are entirely different vehicles on different platforms, and their door lock mechanisms will not be interchangeable. Always make clear to the breaker which model you have, and provide your registration so they can confirm the correct vehicle. Parts listed simply as 'EQS' could relate to either, so specifying saloon or SUV is essential.

No — door lock mechanisms are side-specific and cannot be swapped between the NS (nearside/left) and OS (offside/right) sides; the internal geometry and latch direction are mirrored and not interchangeable. Always specify clearly whether you need NS or OS when contacting a breaker, along with whether it's a front or rear door. Ordering the wrong side is a common and easily avoided mistake.
