Used Nissan 350Z Door Lock Mechanism

The 350Z ran from 2003 to 2009, with a facelift arriving for the 2007 model year, and while the basic two-door coupe body remained throughout, there were detail changes to the doors at the facelift that may affect whether the lock mechanism interchanges directly. You should name the boundary — pre-facelift (2003–2006) versus facelift (2007–2009) — when asking your breaker, and confirm against your specific registration before purchasing. Never assume a pre-facelift unit will drop straight in without verification.

Yes, door lock mechanisms are side-specific — the nearside (NS, passenger/left) and offside (OS, driver/right) units are handed and will not swap across. Always specify clearly which side you need when requesting a quote from a breaker, using NS or OS to avoid any confusion. Fitting the wrong side is not possible without significant modification.

No — the 350Z door lock mechanism is determined by the door itself, not the engine, so whether your car has the 3.5-litre VQ35DE in any of its states of tune makes no difference to fitment. Focus on the model year and the side (NS or OS) when sourcing the part from a breaker.

Trim level does not affect door lock mechanism fitment on the 350Z — the door shell and lock assembly are common across trims regardless of whether the car is a base, GT, Touring or GT4 specification. You may find trim-level cars have different interior door furniture or finishes, but the mechanical lock mechanism itself fits on the basis of model year and side, not trim. Confirm year and NS/OS with your breaker and you can disregard trim when matching this part.

The 350Z was sold in the UK as a two-door coupe and also as a two-door roadster (convertible), and while both body styles share the same basic door count, the roadster's door structure differs from the coupe's. It is therefore important to tell your breaker whether your car is the coupe or roadster body style, as well as confirming model year and NS/OS side, before agreeing on a part. Do not assume a coupe mechanism will be identical to a roadster unit.

The 350Z (2003–2009) and 370Z (2009 onwards) are different generations with distinct door structures, so the lock mechanisms are very unlikely to be interchangeable. Always source a part matched to your specific model and generation, and ask your breaker to confirm compatibility against your registration rather than assuming cross-model fitment.
