Nissan 350Z Ignition Switch Replacement Parts

The Nissan 350Z (2003–2009) uses a conventional keyed ignition switch rather than a push-button start system, so yes, an ignition switch is a genuine part on this car. The switch is located on the steering column and is a real, replaceable component you can source from a breaker. All standard UK-market 350Z variants used this keyed setup throughout the model's production run.

The 350Z received a notable facelift around 2006, which brought revised interior trim and some electrical updates, and it is genuinely uncertain whether the ignition switch is identical across that boundary. You should confirm with the breaker by quoting your exact registration, as they can check the specific part numbers against the donor car before you commit. Do not assume pre-facelift and post-facelift switches are a straight swap without that check.

Trim level does not affect ignition switch fitment on the 350Z — the switch itself is the same unit regardless of whether the car is a base, GT, Touring, or Track specification. You may find cosmetic differences in the surrounding surround or fascia if you are sourcing those parts separately, but the switch mechanism and electrical connector are shared across trims. Any 350Z ignition switch from the correct generation should be considered on its mechanical merits, not its donor car's trim level.

All UK-market Nissan 350Z models used the same naturally aspirated 3.5-litre VQ35DE engine, so there is no engine-variant split to worry about when sourcing an ignition switch. The switch is not engine-specific and you do not need to filter by engine code when searching. Focus instead on the model year and whether the car is pre- or post-facelift, and confirm the part number with the breaker against your registration.

The 370Z succeeded the 350Z from 2009 onward and uses a different platform and steering column design, so its ignition switch is unlikely to be a direct fit. Cross-model compatibility with other Nissan vehicles such as the Skyline or Infiniti G35, which shared some componentry with the 350Z, is possible in principle but cannot be stated as guaranteed here. Always quote your exact registration to the breaker and ask them to match part numbers before purchasing a switch from a different Nissan or Infiniti donor car.

Give the breaker your exact registration number, your model year, and whether your car is a pre-facelift (2003–2005) or post-facelift (2006–2009) example, as these details help them confirm the correct part from their stock. It is also worth asking them to note the part number on the donor switch so you can cross-reference it against your existing unit if possible. A good breaker will check this for you before dispatch, but the more information you provide upfront, the quicker the process.
