Nissan Interstar Ignition Switch Replacement Parts

The Nissan Interstar (sold in the UK roughly 2002–2010) is a van that in most variants uses a conventional barrel-type ignition switch and lock assembly mounted on the steering column, so yes, this part genuinely exists on the vehicle. However, if your Interstar has been fitted with an aftermarket immobiliser or keyless conversion, the original switch arrangement may have been modified, so it is worth checking your setup before ordering. A breaker will be able to confirm the exact assembly from your registration.

The Interstar ran through its UK production life from around 2002 to 2010, and there were detail changes over that period including a mid-life refresh, which means the ignition switch and barrel assembly may differ between early and late vehicles. While some components carried over, you should not assume an early switch drops straight into a later van without checking. Confirm with the breaker by giving them your full registration so they can cross-reference the part number.

For an ignition switch, trim level does not affect fitment — the switch operates the same systems regardless of whether the van is a base S or a higher SE or SX specification. You may find cosmetic differences in the surrounding cowl or column shroud trim depending on specification, but the switch mechanism itself is not trim-dependent. Confirm the part number with the breaker against your registration to be sure.

The ignition switch on the Interstar is a steering-column component and is not determined by which diesel engine variant is fitted — the 2.5 dCi and other engine options do not change the switch itself. What matters more is the generation and any changes to the steering column or immobiliser integration over the production run. Give the breaker your registration so they can match the correct switch and barrel to your specific vehicle.

The Nissan Interstar is the same underlying vehicle as the second-generation Renault Master and Vauxhall Movano of the same era, all built on a shared Renault platform, so there is a reasonable chance of parts compatibility. In practice, ignition switches and lock barrels from these badge-engineered siblings often cross over, but immobiliser coding and key profiles can differ between marques. This is something to confirm directly with the breaker before purchasing, as fitting the wrong barrel could leave you unable to start the van.

On the Interstar, the ignition switch (the electrical contact assembly) and the lock barrel (the mechanical part the key turns) are often separate serviceable components, so you may only need one of them depending on your fault. If the electrical contacts are worn you need the switch unit; if the key no longer turns smoothly the barrel may be the faulty part; if the van has immobiliser issues both may need to be replaced and coded together. Describe your symptoms clearly to the breaker so they can supply the right piece or the complete assembly.
