Cheap Mercedes-Benz EQE Ignition Switch

No — the EQE is a fully electric vehicle and has never been fitted with a traditional ignition switch on any variant. Instead of a key-operated ignition switch, the EQE uses a push-button start system combined with a keyless entry card or key fob, so there is no mechanical ignition switch barrel or cylinder in the conventional sense. If you think you need an ignition switch, you may actually be looking for the start/stop button, the steering column lock module, or the EIS (Electronic Ignition Switch) control unit — confirm exactly what has failed with a breaker or auto-electrician before requesting quotes.

It is unlikely to be a traditional ignition switch, as the EQE has no combustion engine and was never built with one. What is sometimes loosely called an ignition switch on modern Mercedes-Benz vehicles is the EIS (Electronic Ignition Switch) unit on the steering column, but even this functions differently on fully electric models — the push-button start assembly or keycard reader module is more likely what you need. Describe the fault clearly to the breaker and give them your full registration so they can identify the correct component.

Yes, that is very likely — on the EQE the functions associated with a traditional ignition switch are handled by the push-button start system, the keyless go module, or the steering column electronics. If you are experiencing issues with starting, power modes, or the steering lock, the faulty part is almost certainly one of these electronic assemblies rather than a mechanical ignition switch. Let the breaker know your exact symptom and registration, as the correct part number is what will matter for these electronic modules.

The EQE was launched in the UK from 2022 and, as of 2024, remains within its first generation, so parts from the same generation are more likely to be compatible — but electronic control modules on modern Mercedes-Benz vehicles are often software-coded to the specific car. Even if the physical part fits, it may require coding or adaptation by a Mercedes-Benz technician or specialist, so always confirm compatibility with the breaker against your exact registration before purchasing.

The power variant (300, 350, 500 or AMG Line specification) is unlikely to change the fundamental start button or EIS module on its own, but higher-output variants and AMG models can have different steering column or keyless entry configurations. Because these are electronic components that are coded to the vehicle, the registration plate is more important than the trim name when sourcing the right part. Always give the breaker your full registration rather than relying on trim level alone.
