Hyundai Tucson Ignition Barrel Replacement Parts

It depends on the generation. The first-generation Tucson (Mk1, 2004–2010) and second-generation (Mk2, 2010–2015) used a traditional keyed ignition barrel as standard across most variants. The third-generation (Mk3, 2015–2021) and fourth-generation (Mk4, 2021 onwards) increasingly featured push-button start, particularly on higher trims, so your vehicle may not have a conventional ignition barrel at all — check your dashboard before ordering.

The Mk1 (2004–2010) and Mk2 (2010–2015) are distinct generations with different steering column and lock housing designs, so the barrels are very unlikely to be a direct swap. Confirm the part number against your registration with the breaker before purchasing, as fitting the wrong barrel can affect immobiliser pairing. Never assume cross-generation compatibility on a security-critical component like this.

The ignition barrel itself sits in the steering column and is not directly dependent on the drivetrain layout, so 2WD and 4WD variants of the same generation typically share the same barrel. However, the immobiliser system and key coding can vary, so always confirm the exact part reference with the breaker using your registration number. A barrel that physically fits may still need professional coding to your vehicle.

Trim level does not affect the ignition barrel itself — the barrel is determined by generation and steering column, not whether your Tucson is in S, SE, Premium, or Ultimate specification. You may receive a barrel with a slightly different key blade finish or surround depending on what the breaker's donor vehicle had, but the functional fitment is the same within a generation. Confirm the generation and year match rather than worrying about trim.

2015 is right at the boundary between the Mk2 (ending 2015) and the Mk3 (from 2015 onwards), so the exact cutoff for your specific vehicle matters. A 2016 or 2017 barrel would be Mk3, and whether that crosses a compatibility boundary with your particular 2015 car is something you must confirm with the breaker against your registration. This is especially important because the Mk3 generation also saw the introduction of push-button start on some variants, which changes the picture entirely.

A used ignition barrel from a breaker will almost always need to be coded or programmed to your vehicle's immobiliser system — simply swapping the physical barrel rarely allows the engine to start on modern Tucsons. You will typically need a main dealer or auto locksmith with the appropriate diagnostic equipment to complete the job. Factor this cost into your budget when sourcing the part, and make sure the breaker can confirm the barrel's generation and condition before you buy.
