Nissan 370Z Ignition Barrel Replacement Parts

The Nissan 370Z (produced from 2009 onwards) was offered with both a traditional keyed ignition barrel and, on later variants, a push-button start system depending on specification and model year. If your car has a push-button start, there is no conventional ignition barrel fitted and you will need to look for the start button assembly and associated components instead. Check your dashboard to confirm which system your car has before requesting quotes from a breaker.

The Nissan 370Z ran in a single generation throughout its UK production life, with a facelift arriving around 2013 that brought various updates but did not fundamentally change the ignition system architecture on barrel-equipped cars. That said, whether a pre-facelift barrel swaps directly into a post-facelift car is something you should confirm with the breaker against your registration, as electronic pairing with the ECU and immobiliser can make ignition barrels vehicle-specific even within the same generation. Always give the breaker your full registration number so they can cross-reference the exact part.

Trim level — whether your 370Z is a base car, GT, GT Edition, or another UK variant — does not determine which ignition barrel is fitted; what matters is whether your specific car has a keyed ignition or push-button start, and how the immobiliser and key system is coded. A barrel from a GT-trimmed donor car is not inherently better or worse than one from a lower-spec car for fitment purposes, though you may receive a barrel with a different key blade style. Confirm the ignition type and immobiliser compatibility with the breaker against your registration before purchasing.

Ignition barrels on the 370Z are linked to the vehicle's immobiliser and ECU, meaning a used barrel from a breaker will typically need to be paired or coded to your car rather than simply slotted in and used immediately. This is not a straightforward plug-and-play swap in most cases, and you should budget for a Nissan dealer or auto-locksmith to carry out the pairing procedure after fitting. Your breaker can advise whether they supply the barrel with keys and any coding documentation, which can make the process easier.

Yes, if your 370Z has a push-button start system, breakers can often supply the start button assembly, the surrounding ignition switch unit, or related components such as the key reader ring. Be specific when requesting a quote — describe it as a push-button start switch or smart entry start button rather than an ignition barrel, so the breaker supplies the correct part. As with any electronically paired component, confirm with the breaker whether the part will need coding to your vehicle.

The 350Z and 370Z are related but distinct models with different body structures and interior fittings, and an ignition barrel from a 350Z is very unlikely to be a direct swap for a 370Z. Cross-model compatibility of ignition barrels is also complicated by immobiliser coding, making it especially important not to assume interchangeability across different Nissan models. Stick to sourcing a 370Z-specific barrel and confirm the exact part reference with the breaker against your registration.
