Mercedes-Benz X-Class Door Lock Mechanism Replacement Parts

The Mercedes-Benz X-Class is a pickup truck produced from 2017 to 2020, and it does have door lock mechanisms fitted as standard across all variants. Because it is a pickup, you need to specify which door you need the mechanism for: the front doors are conventional hinged doors, and you must tell the breaker whether you need the nearside (NS, passenger left) or offside (OS, driver right) unit, as they are side-specific and not interchangeable. The X-Class was only produced in one generation with no facelift introducing significant structural door changes, so the year range is relatively straightforward, but always confirm against your registration with the breaker.

The X-Class ran as a single generation from 2017 to 2020 with no significant facelift that is known to have altered the door lock mechanism, so a 2017 unit is likely compatible with a 2019 vehicle provided the side matches (NS or OS). However, because this is a used part and minor mid-production running changes can occur, you should confirm the part number against your registration with the breaker before purchasing. Never assume fitment without that check.

The X-Class was sold in the UK in trim levels including Progressive, Power, and Stylish Edition, but trim level does not affect the fitment of the door lock mechanism itself — the door structure and locking hardware are the same across trims. You may find cosmetic differences in door furniture between trims, but the mechanism within the door is what you are replacing and that is not trim-dependent. Just confirm the correct side (NS or OS) and your registration with the breaker.

No — door lock mechanisms are side-specific on the X-Class, as they are on virtually all vehicles, because the internal geometry and linkage orientation differ between the driver's side (OS, offside, right) and passenger's side (NS, nearside, left). Fitting the wrong side will mean the mechanism does not operate correctly, so always specify clearly to the breaker which side you need. Double-check by looking at your vehicle's door and confirming the side before ordering.

No — the door lock mechanism is not affected by whether your X-Class has the 2.3-litre diesel engine or the different power outputs available, nor by whether it is in two-wheel-drive or four-wheel-drive configuration. The mechanism is determined by the door position and side (NS or OS), not by what is under the bonnet or which wheels are driven. Confirm the correct side and your registration with the breaker and engine choice can be disregarded for this part.

No — front and rear door lock mechanisms are not interchangeable on the X-Class, as the front doors are conventionally hinged full-size doors while the rear doors on the double-cab body (the only body style sold in the UK) are also hinged but sized and configured differently, meaning the mechanisms differ in geometry and linkage. You must source the correct mechanism for the specific door position — front or rear — as well as the correct side (NS or OS). Always confirm the exact door position and your registration with the breaker before purchasing.
