Nissan NP300 Ignition Barrel Replacement Parts

The Nissan NP300 Navara does use a conventional ignition barrel and lock cylinder, so it is a genuine part for this vehicle. This applies across the NP300 generation sold in the UK from around 2015 onwards, regardless of engine or trim level. If you are sourcing a used one from a breaker, make sure to quote your registration so they can confirm the correct unit for your exact build.

The D40 Navara and the NP300 Navara are distinct generations with different body structures and steering column designs, and the ignition barrel and lock assembly are unlikely to interchange between them. The NP300 replaced the D40 in the UK from around 2015, representing a significant redesign. Do not assume cross-generation compatibility — confirm with the breaker against your registration before purchasing.

Trim level does not affect ignition barrel fitment on the NP300 Navara — the lock barrel and cylinder are determined by the generation and steering column specification, not by whether the truck is a Visia, Acenta, or Tekna. You may find that higher trims have additional features such as remote locking or a different key type, so check the key and transponder setup matches your own. Confirm the exact part against your registration with the breaker to be sure.

Engine specification — whether your NP300 has the single-turbo or twin-turbo 2.3-litre diesel — does not determine which ignition barrel fits, as the lock assembly is part of the steering column rather than the engine bay. The relevant factors are the model generation and any differences in the key and immobiliser system. Confirm the part against your registration with the breaker to rule out any build-date variation.

Both a 2016 and a 2020 NP300 Navara fall within the same NP300 generation, so there is a reasonable chance the ignition barrel is compatible, but there may have been running changes to the steering column or key system over the production life. This is exactly the kind of question to put to the breaker directly, quoting both registration numbers, so they can compare the part numbers before you commit. Never assume fitment based on year alone.

Used ignition barrels are often sold as a complete lock set including the key barrel, lock cylinder, and sometimes the key itself, and buying the matched set from a breaker is usually the more practical option. Fitting a mismatched barrel without the corresponding transponder or key coding can cause immobiliser issues, so this is worth discussing with the breaker before purchasing. A good breaker should be able to advise on what is included and whether any coding will be required after fitting.
