Second Hand Nissan Interstar Door Lock Mechanism

The Nissan Interstar is a van derived from the Renault Master / Opel Movano platform, produced roughly from 2002 to 2010, and door lock mechanisms are genuine fitment items on this model across all variants. The key details you need are: which side the door is on (NS is nearside, the passenger/left side; OS is offside, the driver/right side), and whether the door is a front hinged door or a rear/side sliding door. For sliding doors, wheelbase also matters because long-wheelbase vans have a larger sliding door than short-wheelbase versions, so always confirm wheelbase with the breaker when quoting for a sliding door lock mechanism.

The Interstar received a facelift in the mid-2000s, broadly around 2006–2007, and while the underlying platform remained shared with the Renault Master generation of that era, there can be detail differences in door furniture and latch assemblies across that boundary. You should not assume a pre-facelift mechanism will drop straight into a post-facelift door without checking, even if the door looks similar. Give the breaker your full registration so they can verify the exact part number against their vehicle before you commit.

The Interstar was offered in trim levels including base/entry fleet spec and higher comfort or crew-van configurations, but trim level does not affect the door lock mechanism itself — fitment is determined by the door position (NS or OS), door type (hinged or sliding), and wheelbase, not by how the van is equipped inside. You may find that higher-spec vans have central locking actuators integrated with the mechanism, so confirm with the breaker whether the unit they have includes an actuator or is a manual latch only, to make sure it matches your van's locking system.

Yes — for the sliding side door specifically, wheelbase is an important factor because the door dimensions differ between short-wheelbase (SWB) and long-wheelbase (LWB) Interstars, and the latch and mechanism can differ accordingly. Front hinged door mechanisms (NS or OS) are not affected by wheelbase, so if you are replacing a front door lock mechanism you only need to confirm the side. Always tell the breaker your wheelbase as well as your registration when enquiring about a sliding door part.

The Nissan Interstar shares its platform with the Renault Master and Vauxhall Movano of the same generation (broadly 2002–2010), and parts including door lock mechanisms are frequently interchangeable across these three badges. However, there were running production changes across model years on all three, so a direct swap is not guaranteed without cross-referencing part numbers. Ask the breaker to check the part number from their donor vehicle against your registration before purchasing, as this is a well-known platform-share and a good breaker will be able to confirm compatibility quickly.

Vans with central locking typically have an electric actuator built into or clipped onto the door lock mechanism, whereas manually-locked doors use a simpler latch assembly, so the two are not directly interchangeable. Whether a specific year or specification of Interstar had central locking as standard or as an option can vary, and this is one detail you should confirm with the breaker against your registration rather than assume. Make sure you tell the breaker whether your van currently has central locking so they can supply a mechanism with the correct actuator arrangement.
