Mercedes-Benz EQA Ignition Switch Replacement Parts

No — the EQA is a fully electric vehicle and has never had a traditional ignition switch on any variant. Instead of a keyed ignition, it uses a push-button start system combined with a keyless entry card or key fob, so there is no ignition barrel or switch in the conventional sense. If you are having starting or power-up issues, the part you may actually need is the push-button start unit, the steering column electronic module, or a component related to the key recognition system — a Mercedes specialist or breaker can help identify the correct part against your registration.

On the EQA, the push-button start replaces what would traditionally be called an ignition switch, so if you are searching for an ignition switch you are most likely after the start/stop button assembly or the associated steering column control module. These are electronic components rather than a mechanical barrel and switch, so the part number and fitment will depend on your exact build — confirm the correct part with a breaker using your registration number. A used-parts breaker dismantling an EQA will be able to advise on which unit matches your car.

Because the EQA does not have a conventional ignition switch at all, there is no like-for-like ignition switch to source from another Mercedes. If you are chasing a fault with the power-up system, the relevant electronic components — such as the start button or the ESL (electronic steering lock) module — are model-specific and should be matched to your EQA's build date and software level by the breaker. Do not purchase a traditional ignition barrel from a petrol or diesel Mercedes expecting it to fit, as the EQA's architecture is entirely different.

Quite possibly — on electric vehicles like the EQA, the electronic steering lock module performs some of the functions associated with the ignition switch on older cars, and a fault here can prevent the car from powering up or releasing the steering. Whether the EQA uses a traditional ESL unit or integrates that function into another module is something to confirm with a breaker against your specific registration and build date. A breaker familiar with EQA dismantling will be best placed to identify and supply the correct component.

Trim level alone — whether Style, AMG Line, or AMG Line Premium — does not change the fundamental power-up architecture of the EQA, so it is not the deciding factor when sourcing these components. What matters more is your car's build date and any factory-fitted options such as the advanced keyless entry system, which can influence the exact specification of the start button or associated modules. Always confirm the part against your registration with the breaker rather than going on trim name alone.
