Fitment questions
Will a central locking motor from a 2009 B-Class fit my 2013 B-Class?
These are different generations — the first-generation B-Class (W245) ran from 2005 to 2011, while the second-generation (W246) ran from 2011 onwards, and the two are not interchangeable for door components like central locking motors. You need to source a motor from the correct W245 or W246 generation to match your car. Confirm the exact part against your registration with the breaker before buying.
Does the year of my Mercedes B-Class matter when buying a used central locking motor?
Yes, generation matters here — the W245 (2005–2011) and W246 (2011–2018, with a facelift around 2015) use different door assemblies and locking mechanisms. Within the same generation, motors from the same body position (driver's side NS/OS, front/rear) are generally more likely to interchange, but you should still confirm against your registration with the breaker.
Does the trim level affect which central locking motor I need for a Mercedes B-Class?
No, trim level does not affect the central locking motor — whether your car is a B180 SE, Sport, or AMG Line, the locking mechanism in the door is the same within a given generation. You may find cosmetic differences in the door cards or handles when removing the old motor, but the motor itself is trim-neutral. Focus on matching the generation (W245 or W246) and door position rather than trim.
Can I use a central locking motor from a W246 B-Class facelift (2015 onwards) in a pre-facelift W246?
The W246 was facelifted around 2015, and while many mechanical components carried over, whether the central locking motor is identical across that boundary is not something that can be confirmed here with certainty. Name the facelift year to your breaker and ask them to check the part number against your specific registration before purchasing.
Does the engine or gearbox type affect which central locking motor I need for a B-Class?
No — engine variant and gearbox type have no bearing on the central locking motor, so it does not matter whether your car is a diesel, petrol, or hybrid. Match the generation and door position (front/rear, NS/OS) and you have the information the breaker needs.
Where do I find the right central locking motor for my Mercedes B-Class — front or rear, driver's or passenger's side?
Central locking motors are door-specific, so you need to identify whether you need a front or rear motor and whether it is the nearside (NS, passenger side) or offside (OS, driver's side), as these are not interchangeable with each other. Have your registration to hand when contacting a breaker so they can cross-reference the correct part for your generation and door position.
