Fitment questions
Does a door lock mechanism from a W220 S-Class fit a W221 S-Class?
No — the W220 (1998–2005) and W221 (2005–2013) are entirely separate generations with different door structures, so the lock mechanisms are not interchangeable. You must match the part to the correct generation. Confirm the exact year of your car with the breaker using your registration to be certain which generation you have.
Will a door lock mechanism from a 2008 S-Class fit my 2012 S-Class?
Both years fall within the W221 generation (2005–2013), so there is a reasonable chance of compatibility, but the W221 received a facelift in 2009 which may have introduced changes to door hardware. Name your exact year and side (NS or OS) to the breaker and ask them to check the part number against your registration before buying.
Does the side (left or right) of the door lock mechanism matter on the S-Class?
Yes, absolutely — door lock mechanisms are side-specific, so a nearside (NS, passenger/left) unit will not fit an offside (OS, driver/right) door and vice versa. Always specify NS or OS when requesting a quote from a breaker, and double-check this matches the door you are replacing.
Does the trim level — for example S350, S500, or AMG — affect which door lock mechanism I need?
No, trim and engine variant do not affect door lock mechanism fitment on the S-Class — the mechanism is determined by the generation and the door side, not by whether the car is an S350, S500, S63 AMG, or any other variant. You may find cosmetic differences in door furniture between specs, but the lock mechanism itself fits the same aperture. Confirm the generation and NS or OS side with your breaker and you should be fine.
Does it matter whether my S-Class is a long-wheelbase (LWB) model when buying a door lock mechanism?
For the front doors, the standard and long-wheelbase S-Class share the same front door, so the lock mechanism should be the same. The rear door on the LWB is a different, longer door, so if you need a rear lock mechanism, you must tell the breaker whether your car is standard or long-wheelbase. Always confirm against your registration to be sure.
Can I use a door lock mechanism from a W222 S-Class on my W223 S-Class?
No — the W222 (2013–2020) and W223 (2020–present) are different generations with distinct door designs, and the lock mechanisms are not a straight swap. Stick to the correct generation when sourcing a used part. Give the breaker your full registration so they can confirm the right unit for your specific car.
