Mercedes-Benz Sprinter Door Lock Mechanism Replacement Parts

These are two distinct generations — the W906 ran from 2006 to 2018 and the W907 from 2018 onwards — and the door architecture changed between them, so mechanisms from one generation will not cross over to the other. Always source a lock mechanism from the same generation as your van. Confirm the exact generation with the breaker against your registration to be sure.

Yes, generation matters significantly — the first-generation NCV2 (W906, 2006–2018) and the current NCV3 (W907, 2018–present) use different door structures, so mechanisms are not interchangeable between them. Within the same generation there may also have been running changes, so always give the breaker your full registration so they can check the correct part for your build date.

Yes, NS (nearside, passenger side) and OS (offside, driver side) lock mechanisms are handed and are not interchangeable, so you must specify which side you need when asking for quotes. On Sprinters you also need to state whether the door is a hinged front door or a sliding side door, as these use different mechanisms entirely. For sliding rear side doors, also confirm the wheelbase with the breaker, as long-wheelbase and standard-wheelbase vans can differ.

Trim level does not affect which door lock mechanism fits your Sprinter — fitment is determined by generation, wheelbase, and which specific door (NS front, OS front, sliding side, or rear) the mechanism came from. Pure, Progressive, and Premium trims share the same door structures within a generation, so a mechanism from any trim will fit provided everything else matches. Cosmetic differences such as paint colour are irrelevant to fitment, as the mechanism itself sits inside the door frame.

The W906 Sprinter received a facelift in 2013, but both pre- and post-facelift vehicles sit within the same generation (2006–2018) and share broadly similar door architecture. That said, running changes can occur around facelift years, so while fitment is plausible within the generation, you should confirm compatibility with the breaker by providing both vehicles' registrations before buying.

The twin rear-wheel (high payload) configuration affects the axle and rear suspension, not the door architecture, so it does not change the door lock mechanism you need. What matters is the generation (W906 or W907), the specific door position (NS, OS, sliding side, or rear hinged), and for sliding doors the wheelbase. Give the breaker your registration and confirm the door position to ensure you get the right part.
