Used Mercedes-Benz EQE Ignition Barrel

No — the EQE is a fully electric vehicle and has never been fitted with an ignition barrel on any variant. Instead of a traditional key-and-barrel system, the EQE uses a push-button start combined with a keyless entry card or smart key fob, so there is no physical barrel to source from a breaker. If you're having trouble starting your EQE or issues with your key system, the part you're likely looking for is the start/stop button assembly, the keyless entry module, or the Electronic Ignition Switch (EIS) unit — confirm which with a breaker or an auto electrician against your registration.

Not quite — on a conventional petrol or diesel car these two parts work together, but the EQE has neither a traditional ignition barrel nor a mechanical key switch. What the EQE does have is an Electronic Ignition Switch (EIS) or steering column switch module that handles the start authorisation electronically, and that is likely what a breaker means when they mention an ignition switch for this vehicle. Always quote your full registration to the breaker so they can identify the correct electronic unit rather than a mechanical barrel, which simply does not exist on this model.

No — this would not be compatible, and it isn't a case of fitment tolerances; the EQE's architecture has no provision for a mechanical ignition barrel at all, so there is nothing to bolt one into. The petrol E-Class uses a physical key and barrel arrangement that is entirely absent from the EQE's steering column and electrical system. If you have a starting or key-recognition fault on your EQE, speak to a breaker about EQE-specific electronic start or keyless entry components instead.

Depending on your fault, the parts most likely to be relevant are the EQE smart key fob, the keyless entry antenna or receiver, the push-button start switch, or the Electronic Ignition Switch (EIS) module. Because these are vehicle-specific electronic components, you should give the breaker your full registration and describe the exact symptom — for example whether the car won't recognise the key, won't wake from sleep, or won't allow the drive selector to engage. A breaker with EQE stock will be able to cross-reference the correct part number against your build.
