Fitment questions
Does the Mercedes-Benz B-Class have a traditional ignition switch, or does it use a keyless start system?
It depends on the generation. The first-generation B-Class (W245, 2005–2011) used a conventional barrel-style ignition switch, while the second-generation (W246, 2011–2018, facelifted 2014) was available with either a traditional key ignition or the optional keyless-go push-button start depending on specification. Before buying a used ignition switch, confirm with the breaker which system your exact car has, as the parts are not interchangeable.
Will a W245 B-Class ignition switch fit a W246 B-Class?
No — the W245 (2005–2011) and W246 (2011–2018) are entirely different generations with different steering column and ignition barrel assemblies, so the switches are not a direct swap. Always source a switch from the same generation as your car and confirm the part against your registration with the breaker.
Does the ignition switch differ between a pre-facelift and post-facelift W246 B-Class?
The W246 was facelifted in 2014, and while many mechanical components carried over, electrical and steering column parts can differ between the pre-facelift (2011–2014) and post-facelift (2014–2018) cars. Whether a switch crosses that boundary is something you should confirm with the breaker against your registration, as subtle changes to the column or wiring loom can affect compatibility.
Does the ignition switch vary between B-Class trim levels — for example, SE, Sport, AMG Line, or Urban?
The trim level itself does not affect which ignition switch is fitted — the same switch assembly is used across SE, Sport, Urban, and AMG Line variants within the same generation. The main variable is whether your car has the keyless-go option rather than a traditional key barrel, which is a factory option rather than a trim-specific feature, so always confirm with the breaker which type your car has.
Does the engine variant affect which ignition switch I need for my B-Class?
No — the ignition switch is not engine-specific on the B-Class, so it does not matter whether your car has a petrol or diesel engine when sourcing this part. What matters is the generation (W245 or W246) and whether your car has a conventional key barrel or push-button keyless start, so quote your registration to the breaker to be sure.
Where can I find a used ignition switch for my Mercedes-Benz B-Class in the UK?
UK vehicle dismantlers (breakers) regularly strip B-Class cars of both generations and will have used ignition switches available. When requesting a quote through Findapart, give your full registration so the breaker can confirm the correct part — especially important given the differences between generations and keyless versus conventional ignition systems.
