Used Ford Fusion Door Lock Mechanism

You need to confirm the year of your vehicle, whether the door is nearside (NS, passenger/left) or offside (OS, driver/right), and whether your Fusion is a 3-door or 5-door, as front door mechanisms differ between those body styles. The Ford Fusion was produced from 2002 to 2012 in the UK, so giving your registration will help the breaker identify the exact build. Engine choice does not affect which lock mechanism you need.

The Ford Fusion ran as a single generation throughout its UK production life from 2002 to 2012, but there were mid-life updates, and internal mechanism designs can change across production years, so a 2004 unit is not guaranteed to be a direct swap for a 2008 car. You should confirm with the breaker whether the specific mechanism from their donor vehicle matches yours, quoting both registration numbers. Side (NS or OS) and door count (3-door or 5-door) must also match.

Yes, this matters — the front door on a 3-door Fusion is a longer door than on a 5-door, and the lock mechanism geometry and rod positions differ accordingly, meaning they are not interchangeable. Always confirm 3-door or 5-door with the breaker alongside the correct side (NS or OS). Rear door mechanisms from a 5-door are a separate part again and should be specified individually.

Trim level does not affect door lock mechanism fitment on the Ford Fusion — the mechanism is determined by generation, body style (3-door or 5-door), and side (NS or OS), not by whether the car is an Ambiente, Zetec, or Ghia. You may find cosmetic differences such as interior door handle colour or finish between trims, but the underlying lock mechanism itself is the same. Confirm the year, body style, and side with the breaker and you should be fine.

No — nearside and offside door lock mechanisms are handed (mirror images of each other) and are not interchangeable, so you must specify the correct side when contacting a breaker. In UK convention, nearside (NS) is the passenger/left side and offside (OS) is the driver/right side. Getting this wrong is one of the most common ordering mistakes, so double-check before you buy.

The Fusion shared its platform and many components across its production run from 2002 to 2012, but detail changes to locking mechanisms did occur over the years and fitment is not guaranteed across the entire range. Your safest approach is to provide your full registration to the breaker so they can cross-reference the exact part from their donor vehicle. Side (NS or OS) and body style (3-door or 5-door) must always match regardless of year.
