Mazda CX-3 Door Replacement Parts

The Mazda CX-3 ran as a single generation from 2015 onwards, with a facelift arriving in 2018 that brought styling and trim updates. Doors from pre-facelift cars (2015–2018) and post-facelift cars (2018 onwards) may differ in panel lines, glass aperture, or mirror mounting, so crossing that 2018 boundary is not a straightforward swap. Always confirm with the breaker whether the door you're buying matches your exact pre- or post-facelift build using your registration.

Your 2016 car is pre-facelift and your 2019 is post-facelift, meaning they sit on either side of the 2018 styling update. The CX-3 is a five-door model throughout, so door count is not a variable here, but panel and aperture details can differ across a facelift. Give the breaker your registration and ask them to confirm the door is from the same facelift phase before buying.

Yes, NS (nearside, passenger side, left) and OS (offside, driver side, right) doors are not interchangeable — each is shaped and hinged for its specific side of the car. When contacting a breaker, always state clearly which side you need to avoid receiving the wrong door. In UK convention, the driver sits on the OS (right), so double-check which side is damaged on your vehicle before placing a quote request.

Trim level does not affect door fitment on the CX-3 — the door shell and frame are the same across SE, SE-L, Sport Nav, GT Sport, and other trim grades. The main cosmetic difference you may notice is mirror finish or door-handle colour, but those are cosmetic details and do not stop the door fitting correctly. Bear in mind that electric window regulators and mirror wiring can vary, so confirm any electrical features with the breaker against your registration.

Colour does not affect fitment at all — any door in the correct generation, side, and facelift phase will fit regardless of what colour the donor car was painted. You will need a respray or colour-match after fitting unless you happen to find a door in your exact colour, which is a bonus but not a fitment requirement. Focus your search on getting the correct side and build phase, then sort the colour with a bodyshop.

The door shell itself fits based on generation, side, and facelift phase, but features built into the door — such as heated, folding, or indicator-equipped mirrors, and electric versus manual window regulators — can vary across the CX-3 range. These variants are not always straightforward to identify by year alone, so you should not assume a door will have the same spec as yours just because the years match. Confirm these specifics with the breaker against your exact registration to make sure the wiring and mechanisms are compatible.
