Used Mercedes-Benz EQS Ignition Switch

No — the EQS is a fully electric vehicle and has never been fitted with a traditional ignition switch on any variant. Instead of a keyed ignition, the EQS uses a keyless push-button start system, so there is no ignition barrel or switch assembly of the conventional type. If your EQS has a starting or key recognition fault, the part you are most likely looking for is the push-button start unit, the steering column electronics module, or possibly the key fob itself.

Almost certainly not — because the EQS is fully electric, it was never built with an ignition switch in the traditional sense, so a direct like-for-like replacement does not exist. A no-start fault on an EQS is more likely related to the push-button start switch, the Electronic Ignition Switch (EIS) control unit on the steering column, the 12V auxiliary battery, or the high-voltage battery system. We'd recommend having the fault codes read by a Mercedes-trained technician first, so you can identify the correct part before approaching a breaker.

Breakers who dismantle EQS vehicles will not have a conventional ignition barrel or key switch to sell, because that component was never fitted to the EQS at any point in its production. What a breaker may be able to supply is the push-button start assembly, the steering column stalk module, or related electronic control units. Confirm the exact part and its part number with the breaker against your vehicle's registration to make sure you get the correct component.

The traditional ignition switch does not exist on any EQS trim, including AMG Line, Business Class, and Executive variants, as all are fully electric with push-button start. If you are sourcing the push-button start switch or a related steering column unit, trim level is unlikely to affect the core electronic fitment, though cosmetic finishes on interior switchgear can vary between trim levels. Confirm the part number against your registration with the breaker to be sure the unit from a donor vehicle matches yours.

No — aside from the fact that the EQS has no ignition switch to replace, the conventional ignition barrel assemblies from combustion-engined Mercedes models like the C-Class or E-Class are entirely different systems that would have no application on the EQS. The EQS uses a fundamentally different starting architecture built around the electric powertrain. If you need a starting or key-recognition component for your EQS, speak to a breaker specifically about EQS donor parts and provide your registration for them to identify the correct unit.
